Blender is a powerful and complex 3D modeling and rendering package.
However, before you can make anything, you need to understand several
concepts used in 3D modelling and related fields. Examples include:

-   Understanding the process of 3D modeling and rendering
-   Understanding how the axis and 3D coordinates work in Blender.
-   Understanding orthographic and perspective views.
-   Local coordinates, parent objects, and child objects.
-   Blender\'s user interface and how to navigate it.
-   Viewing a scene from different camera angles

Don\'t be scared by their long names; a lot of these are actually pretty
intuitive and easy to grasp. Of course, since you\'re not doing any
actual modelling in this unit, you might be tempted to skip ahead, and
that\'s completely fine! Just know that understanding these concepts
well will help you a lot in the long run, and proceeding through
tutorials in order will build a strong foundation for you to build on.
Prior knowledge also plays a huge part in this, so if you\'re coming
from other 3D software, you should already be familiar with these
concepts.

That said, the actual fun (making stuff in Blender) comes in the next
unit. However, keep in mind that Blender is not the kind of software you
can jump into and experiment with. It\'s notorious for having a steep
learning curve. It\'s less like exploring an unfamiliar city and more
like flying a spaceship; if you hop into the pilot\'s seat without
knowing the fundamentals, it\'s going to be near impossible to get off
the ground.

### Blender-specific terminology.

Like any subject, 3D graphics has its own words and terminology used to
describe specific ideas. In this book, important words are
 and defined on their
first use. If you\'ve missed or forgotten the meaning of a word, try
looking it up in the Glossary.

### Things you\'ll need.

In order to follow the tutorials, you need a computer with Blender
installed. You can download the latest Blender release
here.

Depending on your system, you may also need the appropriate Python
installation. Each version of Blender requires a specific version of
Python, but it\'s usually packaged with Blender.

The Blender team has the Blender Long Term Support program which
provides a stable Blender version with 2 years of support. During the 2
year support window, no new features, UI changes, API changes or other
enhancements will be done; only critical fixes will be applied. This
allows teams working on long-lasting blender projects to use a single
supported version over a 2 year period. Long term versions are indicated
below with the LTS suffix and a year indicating the last year of
support.

  Blender version   Python version
  ----------------- ----------------
  2.79              3.5
  2.83 LTS 2022     3.7
  2.90              3.7
  2.93 LTS 2023     3.9
  3.0               3.9
  3.1               3.10
  3.3 LTS 2024      3.10
  3.4               3.10

You can check Python version on Scripting workspace using:

``` python3
import sys
print(sys.version)
```

Since Blender is open-source software, you can download the source code
and build it yourself, but it\'s easier to download a pre-built binary.
As of Blender 3.4.1, compiled releases are provided for the following
operating systems:

-   Windows 8.1, 10, and 11
-   macOS 10.13 Intel · 11.0 Apple Silicon
-   Linux

Along with the website, many Linux distributions have Blender available
in their package repositories, though it may be a slightly older
version. You can use your system\'s package manager to download and
install the package. It\'s also available on steam.

Windows users can also choose between an executable installer (\"setup
wizard\") and a ZIP archive.

After the installation process is finished, Blender should appear in the
Graphics section of your desktop environment application menu.

You may also want to download a 2D image editor, such as GIMP,
Paint.NET, or Photoshop or a media player, such as VLC.

It\'s a good idea to have pencil and paper handy for sketching and
taking notes. There\'s a lot to absorb. Taking notes as you go will pay
dividends later.

### Where to Go for Help

If you get stuck, you can ask for help from other Blender
users in the
appendices.
