**TripoSR** is a state-of-the-art open-source model for **fast** feedforward 3D reconstruction from a single image, developed in collaboration between [Tripo AI](https://www.tripo3d.ai/) and [Stability AI](https://stability.ai/). | |
**Tips:** | |
1. If you find the result is unsatisfied, please try to change the foreground ratio. It might improve the results. | |
2. You can disable "Remove Background" for the provided examples since they have been already preprocessed. | |
3. Otherwise, please disable "Remove Background" option only if your input image is RGBA with transparent background, image contents are centered and occupy more than 70% of image width or height. | |
