# TripoSR Demo |
|
[TripoSR](https://github.com/VAST-AI-Research/TripoSR) is a state-of-the-art open-source model for **fast** feedforward 3D reconstruction from a single image, collaboratively developed by [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. It's better to disable "Remove Background" for the provided examples (except fot the last one) 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. |
