| # Triplane Meets Gaussian Splatting: Fast and Generalizable Single-View 3D Reconstruction with Transformers | |

| </div> | |
| TGS enables fast reconstruction from single-view image in a few seconds based on a hybrid Triplane-Gaussian 3D representation. | |
| This model is trained on Objaverse-LVIS (**~45K** synthetic objects) only. And note that we normalize the input camera pose to a pre-set viewpoint during training stage following LRM, rather than directly using camera pose of input camera as implemented in our original paper. | |
| **Tips:** | |
| 1. If you find the result is unsatisfied, please try to change the camera distance. It perhaps improves the results. | |
| 2. Please wait until the completion of the reconstruction of the previous model before proceeding with the next one, otherwise, it may cause bug. We will fix it soon. | |
