boredengineering/Robots_for_Omniverse/URDF_descriptions/UnitreeRobotics/unitree_h1/README.md | # Unitree H1 Description (MJCF)
Requires MuJoCo 2.2.2 or later.
## Overview
This package contains a simplified robot description (MJCF) of the [H1 Humanoid
Robot](https://www.unitree.com/h1/) developed by [Unitree
Robotics](https://www.unitree.com/). The original URDF and assets were provided
directly by [Unitree Robotics](https://www.unitree.com/) under a [BSD-3-Clause
License](LICENSE).
<p float="left">
<img src="h1.png" width="400">
</p>
## URDF → MJCF derivation steps
1. Added `<mujoco> <compiler discardvisual="false" strippath="false" fusestatic="false"/> </mujoco>` to the URDF's
`<robot>` clause in order to preserve visual geometries.
2. Loaded the URDF into MuJoCo and saved a corresponding MJCF.
3. Manually edited the MJCF to extract common properties into the `<default>` section.
4. Added actuators.
5. Added `scene.xml` which includes the robot, with a textured groundplane, skybox, and haze.
## License

XiaomingY/omni-ies-viewer/README.md | # IES Viewer Omniverse Extension
This extension displays IES profile web for selected light objects. It is particularly useful for visualizing architectural lighting designs. Orientation of measured light distribution profiles could be quickly tested with visual feedback. IES files are resampled to be light weight and consistant to render. [A video demo](https://drive.google.com/file/d/1DxvjVGT6ZlfukfuTvyBu3iXaHz8qvY5Q/view?usp=sharing)
This extension is developed based on the [omni.example.ui_scene.object_info](https://github.com/NVIDIA-Omniverse/kit-extension-sample-ui-scene/tree/main/exts/omni.example.ui_scene.object_info)
Supported light type: sphere light, rectangular light, disk light and cylinder light.
Only Type C IES file is supported currently, which is also the most commonly used type for architectural light.
## Adding This Extension
To add a this extension to your Omniverse app:
1. Go to Extension Manager and turn on Viewport Utility extension
2. Add `git://github.com/XiaomingY/omni-ies-viewer.git?branch=main&dir=exts` to extension search path
3. Turn on IES Viewer Extension

XiaomingY/omni-ies-viewer/exts/IESViewer/docs/README.md | # IES Viewer Omniverse Extension
This extension displays IES profile web for selected light objects. It is particularly useful for visualizing architectural lighting designs. Orientation of measured light distribution profiles could be quickly tested with visual feedback. IES files are resampled to be light weight to render.
This entension is developed based on the [omni.example.ui_scene.object_info](https://github.com/NVIDIA-Omniverse/kit-extension-sample-ui-scene/tree/main/exts/omni.example.ui_scene.object_info)
Supported light type: sphere light, rectangular light, disk light and cylinder light.
Only Type C IES file is supported currently, which is also the most commonly used for architectural light.
## Adding This Extension
To add a this extension to your Omniverse app:
1. Go to Extension Manager and turn on Viewport Utility extension
2. Turn on IESView Extension

Ekozmaster/NvidiaOmniverseRTXRemixTools/README.md | # RTX Remix Tools [ekozerski.rtxremixtools]
Focusing on improving RTX Remix modding workflows, this extension is designed to speed up iteration when producing assets and mods by providing useful UI operations inside Omniverse apps like USD Composer/Create or Code.
It provides some options for the "Right click" context menu to setup ideal replacement assets, as well as some converting operations to ensure assets will be compatible with the Remix runtime.
It is primarily designed to operate on Remix captured scenes, so users can have instant feedbacks on what their mods are gonna look like in the game scenes and iterate faster.
## Available Tools
### Fix Meshes Geometry
<i>(Operation is performed on every mesh of a USD/USDA source file and can\'t be undone)</i>
Interpolation Mode
- RTX Remix runtime only supports meshes with "vertex" interpolation mode, in which "points" "normals" and "uvs" arrays
must have the same length, but DCC tools usually export the mesh using "faceVarying" interpolation mode.
This operation reorganizes the geometry to be compatible with the runtime.
- See: "Interpolation of Geometric Primitive Variables" - https://openusd.org/dev/api/class_usd_geom_primvar.html
- This operation only applies for meshes inside the mods folder, not the captured ones.
UV Maps
- The runtime supports one single UV map per mesh, which should have one of a few known names, so this script finds many variations, picks one and renames to the standard "primvars:st", while also setting the appropriate type as "TextureCoordinate" (TexCoord2fArray / TexCoord2f[]). The other UVmaps are discarded.
Unused Primvars
- displayColor and displayOpacity are now removed from the mesh.
### Setup for Mesh Replacement
Exports the selected mesh in a selected path, already setting up the replacements and references to work in the runtime, so for every change the user only needs to:
- Open the exported mesh in it's DCC of choice, make the changes and export again (with the right settings, triangulating faces, no materials, etc.)
- Back in OV, refresh the reference to see the changes in the captured scene.
- Use the "Fix Meshes Geometry" again to make it Remix-compatible.
- Enjoy.
The original mesh is kept in case the user only wants to add more models. Make sure to delete it if the intention is to completely replace the original mesh.
### Add Model
If the user already has authored USD models, this option allows to select multiple models and add to the mesh_HASH prim.
### Add Material
This option allows to select a material .MDL file (AperturePBR_Opacity.mdl or AperturePBR_Translucent.mdl) to add a material prim to the mesh_HASH prim.
### Original Draw Call Preservation
Allows to set the "custom int preserveOriginalDrawCall" attribute to indicate whether the runtime should be forced to render the original mesh or not. Must be set to 1 when placing custom lights or else the original mesh disappears. PS: Remember to set this to 0 if you want to make a mesh replacement and remove the original mesh.
### Select Source Mesh
Quick way to select the originial source mesh_HASH prim in the scene when you have an instance prim selected.
<br>
## Things to Keep in mind
- In a capture scene, any changes made to the "inst_SOMEHASH_x" prims won't show up in the runtime, so every changes must be done in the "mesh_SOMEHASH" they're referencing. Whenever the user clicks a inst_ prim to perform an action like Fixing geometry or Add Model (Ex: Right clicking in the 3D viewport), this tool will try to find the referenced mesh_SOMEHASH and perform the operations in it instead.
- Having that in mind, always keep an eye in the "Layers" tab to check if you have done any changes to the "instances" path. Try to delete those changes as much as possible.
- The only material types that work in the runtime are described in the AperturePBR_Opacity.MDL and AperturePBR_Translucent.MDL, and every mesh must be triangulated. If you want to add a model you got from somewhere else like an asset store, make sure to convert the assets to work in the runtime.
- When placing lights in the scene, it is necesssary to set an int "preserveOriginalDrawCall" to "1" in order to keep rendering the original mesh. If another layer is setting this flag somewhere and you want to replace/remove the original mesh in your own layer, you will notice that the original mesh can't be removed without setting this flag back to "0". You can do that on your own layer, set it back to "0", but make sure your layer comes on top of the other one that sets it to true.

Ekozmaster/NvidiaOmniverseRTXRemixTools/exts/ekozerski.rtxremixtools/docs/README.md | # RTX Remix Tools [ekozerski.rtxremixtools]
Focusing on improving RTX Remix modding workflows, this extension is designed to speed up iteration when producing assets and mods by providing useful UI operations inside Omniverse apps like USD Composer/Create or Code.
It provides some options for the "Right click" context menu to setup ideal replacement assets, as well as some converting operations to ensure assets will be compatible with the Remix runtime.
It is primarily designed to operate on Remix captured scenes, so users can have instant feedbacks on what their mods are gonna look like in the game scenes and iterate faster.
## Available Tools
### Fix Meshes Geometry
<i>(Operation is performed on every mesh of a USD/USDA source file and can\'t be undone)</i>
Interpolation Mode
- RTX Remix runtime only supports meshes with "vertex" interpolation mode, in which "points" "normals" and "uvs" arrays
must have the same length, but DCC tools usually export the mesh using "faceVarying" interpolation mode.
This operation reorganizes the geometry to be compatible with the runtime.
- See: "Interpolation of Geometric Primitive Variables" - https://openusd.org/dev/api/class_usd_geom_primvar.html
- This operation only applies for meshes inside the mods folder, not the captured ones.
UV Maps
- The runtime supports one single UV map per mesh, which should have one of a few known names, so this script finds many variations, picks one and renames to the standard "primvars:st", while also setting the appropriate type as "TextureCoordinate" (TexCoord2fArray / TexCoord2f[]). The other UVmaps are discarded.
Unused Primvars
- displayColor and displayOpacity are now removed from the mesh.
### Setup for Mesh Replacement
Exports the selected mesh in a selected path, already setting up the replacements and references to work in the runtime, so for every change the user only needs to:
- Open the exported mesh in it's DCC of choice, make the changes and export again (with the right settings, triangulating faces, no materials, etc.)
- Back in OV, refresh the reference to see the changes in the captured scene.
- Use the "Fix Meshes Geometry" again to make it Remix-compatible.
- Enjoy.
The original mesh is kept in case the user only wants to add more models. Make sure to delete it if the intention is to completely replace the original mesh.
### Add Model
If the user already has authored USD models, this option allows to select multiple models and add to the mesh_HASH prim.
### Add Material
This option allows to select a material .MDL file (AperturePBR_Opacity.mdl or AperturePBR_Translucent.mdl) to add a material prim to the mesh_HASH prim.
### Original Draw Call Preservation
Allows to set the "custom int preserveOriginalDrawCall" attribute to indicate whether the runtime should be forced to render the original mesh or not. Must be set to 1 when placing custom lights or else the original mesh disappears. PS: Remember to set this to 0 if you want to make a mesh replacement and remove the original mesh.
### Select Source Mesh
Quick way to select the originial source mesh_HASH prim in the scene when you have an instance prim selected.
<br>
## Things to Keep in mind
- In a capture scene, any changes made to the "inst_SOMEHASH_x" prims won't show up in the runtime, so every changes must be done in the "mesh_SOMEHASH" they're referencing. Whenever the user clicks a inst_ prim to perform an action like Fixing geometry or Add Model (Ex: Right clicking in the 3D viewport), this tool will try to find the referenced mesh_SOMEHASH and perform the operations in it instead.
- Having that in mind, always keep an eye in the "Layers" tab to check if you have done any changes to the "instances" path. Try to delete those changes as much as possible.
- The only material types that work in the runtime are described in the AperturePBR_Opacity.MDL and AperturePBR_Translucent.MDL, and every mesh must be triangulated. If you want to add a model you got from somewhere else like an asset store, make sure to convert the assets to work in the runtime.
- When placing lights in the scene, it is necesssary to set an int "preserveOriginalDrawCall" to "1" in order to keep rendering the original mesh. If another layer is setting this flag somewhere and you want to replace/remove the original mesh in your own layer, you will notice that the original mesh can't be removed without setting this flag back to "0". You can do that on your own layer, set it back to "0", but make sure your layer comes on top of the other one that sets it to true.

## Contribution Rules
#### Issue Tracking
* All enhancement, bugfix, or change requests must begin with the creation of a [TensorRT Issue Request](https://github.com/nvidia/TensorRT/issues).
* The issue request must be reviewed by TensorRT engineers and approved prior to code review.
#### Coding Guidelines
- All source code contributions must strictly adhere to the [TensorRT Coding Guidelines](CODING-GUIDELINES.md).
- In addition, please follow the existing conventions in the relevant file, submodule, module, and project when you add new code or when you extend/fix existing functionality.
- To maintain consistency in code formatting and style, you should also run `clang-format` on the modified sources with the provided configuration file. This applies TensorRT code formatting rules to:
- class, function/method, and variable/field naming
- comment style
- indentation
- line length
- Format git changes:
```bash
# Commit ID is optional - if unspecified, run format on staged changes.
git-clang-format --style file [commit ID/reference]
```
- Format individual source files:
```bash
# -style=file : Obtain the formatting rules from .clang-format
# -i : In-place modification of the processed file
clang-format -style=file -i -fallback-style=none <file(s) to process>
```
- Format entire codebase (for project maintainers only):
```bash
find samples plugin -iname *.h -o -iname *.c -o -iname *.cpp -o -iname *.hpp \
| xargs clang-format -style=file -i -fallback-style=none
```
- Avoid introducing unnecessary complexity into existing code so that maintainability and readability are preserved.
- Try to keep pull requests (PRs) as concise as possible:
- Avoid committing commented-out code.
- Wherever possible, each PR should address a single concern. If there are several otherwise-unrelated things that should be fixed to reach a desired endpoint, our recommendation is to open several PRs and indicate the dependencies in the description. The more complex the changes are in a single PR, the more time it will take to review those changes.
- Write commit titles using imperative mood and [these rules](https://chris.beams.io/posts/git-commit/), and reference the Issue number corresponding to the PR. Following is the recommended format for commit texts:
```
#<Issue Number> - <Commit Title>
<Commit Body>
```
- Ensure that the build log is clean, meaning no warnings or errors should be present.
- Ensure that all `sample_*` tests pass prior to submitting your code.
- All OSS components must contain accompanying documentation (READMEs) describing the functionality, dependencies, and known issues.
- See `README.md` for existing samples and plugins for reference.
- All OSS components must have an accompanying test.
- If introducing a new component, such as a plugin, provide a test sample to verify the functionality.
- To add or disable functionality:
- Add a CMake option with a default value that matches the existing behavior.
- Where entire files can be included/excluded based on the value of this option, selectively include/exclude the relevant files from compilation by modifying `CMakeLists.txt` rather than using `#if` guards around the entire body of each file.
- Where the functionality involves minor changes to existing files, use `#if` guards.
- Make sure that you can contribute your work to open source (no license and/or patent conflict is introduced by your code). You will need to [`sign`](#signing-your-work) your commit.
- Thanks in advance for your patience as we review your contributions; we do appreciate them!
#### Pull Requests
Developer workflow for code contributions is as follows:
1. Developers must first [fork](https://help.github.com/en/articles/fork-a-repo) the [upstream](https://github.com/nvidia/TensorRT) TensorRT OSS repository.
2. Git clone the forked repository and push changes to the personal fork.
```bash
git clone https://github.com/YOUR_USERNAME/YOUR_FORK.git TensorRT
# Checkout the targeted branch and commit changes
# Push the commits to a branch on the fork (remote).
git push -u origin <local-branch>:<remote-branch>
```
3. Once the code changes are staged on the fork and ready for review, a [Pull Request](https://help.github.com/en/articles/about-pull-requests) (PR) can be [requested](https://help.github.com/en/articles/creating-a-pull-request) to merge the changes from a branch of the fork into a selected branch of upstream.
* Exercise caution when selecting the source and target branches for the PR.
Note that versioned releases of TensorRT OSS are posted to `release/` branches of the upstream repo.
* Creation of a PR creation kicks off the code review process.
* Atleast one TensorRT engineer will be assigned for the review.
* While under review, mark your PRs as work-in-progress by prefixing the PR title with [WIP].
4. Since there is no CI/CD process in place yet, the PR will be accepted and the corresponding issue closed only after adequate testing has been completed, manually, by the developer and/or TensorRT engineer reviewing the code.
#### Signing Your Work
* We require that all contributors "sign-off" on their commits. This certifies that the contribution is your original work, or you have rights to submit it under the same license, or a compatible license.
* Any contribution which contains commits that are not Signed-Off will not be accepted.
* To sign off on a commit you simply use the `--signoff` (or `-s`) option when committing your changes:
```bash
$ git commit -s -m "Add cool feature."
```
This will append the following to your commit message:
```
Signed-off-by: Your Name <[email protected]>
```
* Full text of the DCO:

rcervellione-nv/omni.rhinocompute/README.md | # About
This is an extension designed to run in a Nvidia Omniverse application such as Create or Machinima. The extension creates a link to a Rhino.Compute Server [https://developer.rhino3d.com/guides/compute/] allowing you to run Rhino commands such as quad remesh or Grasshopper files.
This is designed to be a sample to extend. there are examples for using some basic rhino command like volume and quad remesh as well as running a Grasshopper script. Use this as a starting point to integrate your grasshopper scripts and functions directly into Omniverse and create the necessary UI elements.
# Using It
- "app" - It is a folder link to the location of your *Omniverse Kit* based app.
- "exts" - is the folder where you add to extension search path. (Extension Manager -> Gear Icon -> Extension Search Path).
Open this folder using Visual Studio Code. It will suggest you install a few extensions that will make python experience better.
Look for "cerver.util.rhinocompute" extension in extension manager inside Omniverse Create and enable it. Try applying changes to any python files, it will hot-reload and you can observe results immediately.
The first time you enable it will take some time to load. this is because all of the required packages from rhino and rhino compute will be installed into your Omniverse python library via a automatic pip install.

For the second option this script emulates the stream of chunks, generated by splitting an input WAV audio file.

mnaskret/omni-tetGen/README.md | # omni-tetGen
An omniverse extension to generate soft body meshes
## Description:
omni-tetGen uses the famous tetgen mesh generator developed by Hang Si to create tetrahedral and edge meshes for soft body simulation. The extension allows for a user-friendly drag-and-drop mechanism for input mesh data in standard .obj format. Then, it runs the python tetgen wrapper to create meshes which are converted to numpy arrays and described with additional infomration like edges rest lengths or tetrahedra volumes. Generated mesh is added to the stage with additional attributes:
- edge
- edgesRestLengths
- elem
- tetrahedronsRestVolumes
- inverseMasses
## PBD .ogn node
Additionally, an omniverse node with a simple Position Based Dynamics algorithm implementation with CUDA kernels is attached in order to test generated meshes.
## Usage
- [Install omniverse](https://www.nvidia.com/en-us/omniverse/) with e.g. create environment
- Go to: Window -> Extensions -> Gear icon -> Add extension search path: `git://github.com/mnaskret/omni-tetGen.git?branch=main`
- Find Tetrahedralizer in the list of extensions and turn it on (preferably with autoload)
- In the Tetrahedralizer window you can drop any .obj file from Omniverse Content browser, choose preferred options and generate a cool mesh
- Add a graph with PBDBasicGravity node or create your own node that utilizes mesh extra attributes to have fun with your mesh

These are some tools I've made that are intended for use with Nvidia's RTX Remix. Right now I have 3:
* **MagicUSDA** - Allows you to generate .usda files based on your gameReadyAssets folder
* **LightAdjuster** - A simple script that allows you to adjust light intensity and color temperature in a specified .usda file
* **RemixMeshConvert** - This script will convert meshes to be (more) compatible with Remix
These should hopefully help with setting up mods for Remix quickly and easily.

Kim2091/RTXRemixTools/LightAdjuster/README.md | # **Remix Light Adjuster**
*Written with the assistance of Bing*
This script adjusts the intensity and/or color temperature values in a file.
$\color{#f7d26a}{\textsf{Please back up your usda files before running!}}$
## Usage
To use this script, run the following command:
`python LightAdjuster.py file_path`
where `file_path` is the path to the .usda file to modify.
There are several additional options that can be used with this script:
* `-s` or `--start-line` - This option allows you to specify the line number to start modifying at. The default value is 1.
* `-l` or `--log` - This option enables logging of the changed lines. If this option is used, a log of the changed lines will be printed to the console and written to a file named `changes.log`.
* `-p` or `--percentage` - This option specifies the percentage to adjust the value by. This option is required.
* `-ai` or `--adjust-intensity` - This option enables adjustment of the intensity value using `-p`.
* `-act` or `--adjust-color-temperature` - This option enables adjustment of the color temperature value using `-p`.
For example, to adjust the intensity value in a file named `data.txt`, starting at line 5, and logging the changes, you would run the following command:
`python adjust_file.py data.txt -s 5 -l -ai -p 0.5`
This would adjust the intensity value in all lines containing `float intensity =`, starting at line 5, by multiplying it by 0.5. A log of the changed lines would be printed to the console and written to a file named `changes.log`.
## Description
This script reads the specified file and modifies lines that contain either `float intensity =` or `float colorTemperature =`, depending on which value is being adjusted. The value is multiplied by the specified percentage and the line is updated with the new value. If logging is enabled, a log of the changed lines is printed to the console and written to a file named `changes.log`.
After all lines have been processed, the script prints a message indicating how many lines were changed.

Kim2091/RTXRemixTools/MagicUSDA/README.md | # Remix USDA Generator
*Written with the assistance of Bing and ChatGPT*
$\color{#f7d26a}{\textsf{Please back up your usda files to a separate folder before running!}}$
This is a script to generate `.usda` files from your gameReadyAssets folder. It detects any of these map types in your folder:
- emissive
- normal
- metallic
- rough
## Usage
How to use this script:
`python MagicUSDA.py -d path\to\gameReadyAssets`
There are some additional functions:
* `-o` - Change the output usda file names.
* `-m` - Split the output USDA files into separate entries for each map type (e.g. mod_emissive.usda, mod_metallic.usda). Works with `-o` to change the base file name.
* `-a` - Add sublayers made with `-m` to the mod.usda file. Not compatible with custom files specified by `-o`, will only modify mod.usda. Works with `-m` and `-o`.
* `-g` - Toggle generating hashes for file names before the suffix. Useful for files with generic names like test.dds. Diffuse textures must be identical to Remix dumps.
* `-s` - Change between the AperturePBR_Opacity and AperturePBR_Translucent material shader types. Using this, you can generate separate .usda files for normal or translucent objects easily
* `-r` _**Currently broken**_ - Specify a separate folder to use as a reference for generating diffuse texture hashes. Searches for files in the reference directory based on file names from the base directory. If not provided, uses the main directory to generate hashes. Useful with folders like captures or game texture rips.
The `.usda` files generated by this script serve to replace textures in your Remix games, allowing you to swap out textures and utilize additional map types to enhance the game's visuals.
This script is intended to be used with original diffuse textures, which are required for it to function correctly. It generates a `mod.usda` file for use in your game through Remix. It was designed with [chaiNNer](https://chainner.app/) in mind, however you can use this with any textures you've created. Be aware that this script will overwrite any pre-existing `mod.usda` files in your directory!

<details>
<summary>Old description:</summary>
*Based on a script originally written by E-man*
$\color{#f7d26a}{\textsf{Please back up your USD and USDA files before running!}}$
**How to use this script:**
To convert a single file:
`python RemixMeshConvert.py [input.usda] [output.usda]`
To batch convert a folder:
`python RemixMeshConvert.py path\to\input\folder path\to\output\folder -f [usd or usda]`
**Arguments:**
`-f` `--output-format` - This controls the output format when using the script in **batch** mode
**Description:**
This script takes USD files as input, makes a copy named as the output, converts the interpolation of all meshes in the given USD file from face-varying to vertex, and finally saves the modified stages to the new USD files. It can process a single file or a folder of files, and also includes a dictionary of aliases for replacing specific primvar names with `float2[] primvars:st1`.
**For your final exports to use in-game, please save as USD! USDA files are very inefficient in comparison**
Please refer to `requirements.txt` for necessary Python libraries.

# The Unreasonable Effectiveness of Synthetic Data
Created By:
[George Igwegbe](https://www.linkedin.com/in/george-igwegbe/)
Public Project Link:
[GitHub](https://github.com/gigwegbe/synthetic_data_with_nvidia_replicator_and_edge_impulse) | [Edge Impulse](https://studio.edgeimpulse.com/public/187851/latest)
## Introduction
Building an object detection model can be tricky since it requires a large dataset. Sometimes, data can be few or not diverse enough to train a robust model. Synthetic data offers an alternative to generating well-represented datasets to build a quality model. By applying domain randomization, we developed photorealistic datasets, trained a neural network, and validated the model using real datasets. To create a diverse dataset, we created a variety of simulated environments with randomized properties: changing lighting conditions, camera position, and material textures. We also show that synthetic, randomized datasets can help generalize a model to adapt to the real-world environment.
## Story
We wanted to replicate the [object detection](https://www.youtube.com/watch?v=Vwv0PJPeC4s) work by Louis Moreau, but this time using synthetic data rather than real data. The project aims to demonstrate how to build and deploy the Edge Impulse object detection model using synthetic datasets generated by Nvidia Omniverse Replicator. The Replicator is an Nvidia Omniverse extension that provides means of generating physically accurate synthetic data.
## Why Synthetic Data?
Computer vision tasks such as classification, object detection, and segmentation require a large-scale dataset. Data collected from some real-world applications tend to be narrow and less diverse, often collected from a single environment, and sometimes is unchanged and stays the same for the most time. In addition, data collected from a single field tend to have fewer examples of tail-end scenarios and rare events, and we cannot easily replicate these situations in the real world.

 |
Consequently, models trained in a single domain are brittle and often fail when deployed in another environment; thus, it requires another training cycle to adapt to the new environment. It raises the question, how can we efficiently and cheaply collect generalized data across several domains? A simple unreasonable effective solution is Domain Randomization, which varies the texture and colour of the foreground object, the background image, the number of lights in the scene, the pose of the lights, and the camera position etc. Domain randomization can further improve the variability in the texture of synthetic data of rare events generated in the simulator.
> The purpose of domain randomization is to provide enough simulated variability at training time such that at test time the model is able to generalize to real-world data.” - Tobin et al, Domain Randomization for Transferring Deep Neural Networks from Simulation to the Real World, 2017

Nvidia Replicator enables us to perform Domain Randomization. The Replicator is one module within the Omniverse family, and it offers tools and workflow to generate data for various computer vision and non-visual tasks. The Replicator is a highly interoperable tool that integrates with over 40+ modelling/rendering applications across different verticals. The seamless integration is possible thanks to Pixar's Universal Scene Description(USD), which serves as a protocol for various applications such as Blender, 3DMax, Maya, Revit, C4D etc., to work with the Nvidia Replicator.
## Data-Centric Workflow
Traditional machine learning workflow is often model-centric, focusing more on the model's development by iteratively improving the algorithm design, etc. In this project, we chose the Data-centric approach, where we fixed the model and iteratively improved the quality of the generated dataset. This approach is more robust since we know our model is as good as the dataset. This method hence systematically changes the dataset performance on an AI task. At its core, it is thinking about ML in terms of data, not the model.

## Requirements
- Nvidia Omniverse Replicator
- Edge Impulse Studio
- Logitech Webcam HD Pro - C920
### Hardware and Driver Setup
Nvidia Omniverse Replicator is a computation-intensive application requiring a moderate-size GPU and decent RAM. My hardware setup consists of 32GB RAM, 1TB storage space and 8GB GPU with an Intel i9 processor.
Hardware Specification | Hardware Specification
--- | ---
 | 
The application can run on both Windows and Linux operating systems. For this experiment, we used Ubuntu 20.04 LTS distro, given Ubuntu 18.04 is no longer supported by Nvidia Omniverse as of November 2022. In addition, we selected the appropriate Nvidia driver, v510.108.03 and installed it on a Linux machine.
Software Specification | Software Specification
--- | ---
 | 
## Experiment Setup and Data Generation
The environment for the experiment consists of movable and immovable objects (dynamic and static positioning objects). The immovable object consists of Lights, a Table and two Cameras. At the same time, the movable objects are the cutlery which is a spoon, fork and knife. We will use domain randomization to alter the properties of some of the movable and immovable objects. Assets which include objects and scenes are represented in the Replicator as USD.
Experimental Setup |
--- |
 |
Every object in Omniverse Replicator is represented as USD. A 3D model file with varying extensions such as obj, fbx, and glif can be imported into the Replicator using Nvidia Omniverse's CAD Importer extension. The extension converts the 3D files into USD. We imported our assets (Table, knife, spoon and fork) into the simulator by specifying the path of the assets.
Rectangular Light | Dome Light
--- | --- |
 | 
Lightning plays a crucial role in data generation. There are different built-in lighting types in the Nvidia replicator. We choose two rectangular lights and a dome light since they give us better lighting options and capabilities for generating photorealistic images. The rectangular light emulates light generated from a panel, and the dome light lets you dynamically lighten the entire scene. We randomized some light parameters such as temperature and intensity, and both parameters were sampled from a <strong>normal distribution</strong>. In addition, the scale parameter was sampled from a <strong>uniform distribution</strong> while keeping the rotation and position of the lights fixed.
```python
# Lightning setup for Rectangular light and Dome light
def rect_lights(num=2):
lights = rep.create.light(
light_type="rect",
temperature=rep.distribution.normal(6500, 500),
intensity=rep.distribution.normal(0, 5000),
position=(-131,150,-134),
rotation=(-90,0,0),
scale=rep.distribution.uniform(50, 100),
count=num
)
return lights.node
def dome_lights(num=1):
lights = rep.create.light(
light_type="dome",
temperature=rep.distribution.normal(6500, 500),
intensity=rep.distribution.normal(0, 1000),
position=(0,0,0),
rotation=(270,0,0),
count=num
)
return lights.node
```
We fixed the position and rotation, selected the tabletop materials, chose an additional <strong>Mahogany</strong> material, and alternated the material in the data generation process.
```python
# Import and position the table object

To improve our dataset's quality further, we chose two cameras of different resolutions, which we strategically positioned in various locations within the scene. In addition, we varied the position of the cameras in a different version of the data generation process.
```python
# Multiple setup cameras and attach it to render products
camera = rep.create.camera(focus_distance=focus_distance, focal_length=focal_length, position=cam_position, rotation=cam_rotation, f_stop=f_stop)
camera2 = rep.create.camera(focus_distance=focus_distance2, focal_length=focal_length2, position=cam_position2, rotation=cam_rotation, f_stop=f_stop)
# Will render 1024x1024 images and 512x512 images
render_product = rep.create.render_product(camera1, (1024, 1024))
render_product2 = rep.create.render_product(camera2, (512, 512))
```
Finally, for the movable objects, which include a knife, spoon and fork, we ensure that these objects can only translate within the bound of the table. So we chose a bounding position where the objects were expected to translate and rotate with the table. We sampled position and rotation from a uniform distribution while maintaining the number of movable objects generated at each iteration to be five.
```python
# Define randomizer function for CULTERY assets.
def cutlery_props(size=5):
instances = rep.randomizer.instantiate(rep.utils.get_usd_files(current_cultery), size=size, mode='point_instance')
with instances:
rep.modify.pose(
position=rep.distribution.uniform((-212, 76.2, -187), (-62, 76.2, -94)),
rotation=rep.distribution.uniform((-90,-180, 0), (-90, 180, 0)),
)
return instances.node
```
At this juncture, we have instantiated all objects in our scene. We can now run the randomizer to generate 50 images at each synthetic generation cycle.
```python
# Register randomization
with rep.trigger.on_frame(num_frames=50):
rep.randomizer.table()
rep.randomizer.rect_lights(1)
rep.randomizer.dome_lights(1)
rep.randomizer.cutlery_props(5)
# Run the simulation graph
rep.orchestrator.run()
```
To ensure we generated photorealistic images, we switched to <strong>RTXinteractive(Path Tracing)</strong> mode, which gave high-fidelity renderings.

## Data Distribution and Model Building
Data Distribution of different items |
--- |
 |
Following the data-centric philosophy, We generated three versions of the dataset. The first version, <strong>V1</strong>, consists of generated images normal to the camera position, and <strong>V2</strong> represents images generated at an angle of 60 degrees to the camera position with a mahogany table top. <strong>V3</strong> comprises images normal to the camera position while the cutlery were suspended in space.
V1 - Normal to the object |
--- |
 |
<table>
<tr>
<td>V2 - Angled to the object</td>
<td>V3 - Normal to the object and object suspended in space</td>

We uploaded the generated images to Edge Impulse Studio, where we annotated the dataset into different classes. We carefully annotated each dataset version and trained using the <strong>Yolov5</strong> object detection model. We tried a couple of input sizes ranging from 320, 512 and 1024 pixels before settling with <strong>320</strong>. Edge Impulse provided an excellent version control system for models, which enabled us to track model performance across different dataset versions and hyperparameters.

### Testing of Object Detection Models with Real Objects
We used the Edge Impulse CLI tool to evaluate the model's accuracy by downloading, building and running the model locally. A Logitech C920 webcam streamed the live video of objects on a table from 50 cm to 80 cm from the camera. The position of the camera remains fixed during the experiment. The clips below show that the trained model does not generalize well to real-world objects. Thus we needed to improve the model by uploading, annotating and training the model with the V2 dataset.
V1 failure - model failed to identify objects |
--- |
 |
We observed improved model performance when trained with the V2 dataset. The model could identify various objects distinctly, although the model failed when we changed the objects' orientations. Thus, we trained the model with the remaining V3 dataset to mitigate these issues and increase other hyperparameters, such as epochs from 500 to 2000. We also tested the performance of our object detector on real objects with different background textures, and the model performed well in these conditions.
V2 success - model can identify objects |
--- |
 |
V2 failure - model failed to identify objects in different orientations |
--- |
 |
After several cycles of iterating over various hyperparameters, we got a model that generalizes well across different orientations.
V3 success - model can identify objects in different orientations |
--- |
 |
V3 success - model can identify different materials |
--- |
 |
The core idea behind the data-centric approach to solving ML problems is to create more data around the failure points of the model. We improved the model by iteratively improving the data generation, especially in areas where the model had previously failed.
## Conclusion
In this work, we learned how the domain randomization approach helps generate quality and well-generalized datasets for the object detection task. We also demonstrated the effectiveness of data-centric machine learning workflow in improving the model performance. Although this work is restricted to visual problems, we can extend domain randomization to other sensors such as lidar, accelerometer, and ultrasonic sensors.

mati-nvidia/window-menu-add/README.md | # Window Menu Add
An example extension showing how to create a window and add it to the `Window` menu so that it can be shown and hidden
using the menu item in the `Window` menu.
## App Link Setup
If `app` folder link doesn't exist or broken it can be created again. For better developer experience it is recommended to create a folder link named `app` to the *Omniverse Kit* app installed from *Omniverse Launcher*. Convenience script to use is included.
Run:
```
> link_app.bat
```
If successful you should see `app` folder link in the root of this repo.
If multiple Omniverse apps is installed script will select recommended one. Or you can explicitly pass an app:
```
> link_app.bat --app create
```
You can also just pass a path to create link to:
```
> link_app.bat --path "C:/Users/bob/AppData/Local/ov/pkg/create-2021.3.4"
```
## Sharing Your Extensions
This folder is ready to be pushed to any git repository. Once pushed direct link to a git repository can be added to *Omniverse Kit* extension search paths.
Link might look like this: `git://github.com/[user]/[your_repo].git?branch=main&dir=exts`
Notice `exts` is repo subfolder with extensions. More information can be found in "Git URL as Extension Search Paths" section of developers manual.
To add a link to your *Omniverse Kit* based app go into: Extension Manager -> Gear Icon -> Extension Search Path
