## Turn a 2D image into a 3D point map with [MoGe](https://wangrc.site/MoGePage/)
NOTE:
* The maximum size is set to 800px for efficiency purpose. Oversized images will be downsampled.
* The color in the 3D viewer may look dark due to rendering of 3D viewer. You may download the 3D model as .glb or .ply file to view it in other 3D viewers.
