Differential Gaussian Rasterization

This is a forked repository of the rasterization pipeline from the paper "3D Gaussian Splatting for Real-Time Rendering of Radiance Fields". I have made some extensions to it:

• main branch incorporates only the forward pass of depth, which is used for depth visualization.
• 4th-degree: add the 4th degree of SH
• depth: add both the forward and backward pass of depth, which is used for some tasks with depth supervision.
• latest: is the dev branch that contains acc and depth visualization, together with depth backward pass.
• depth-mean3D: add additional backward pass to the mean3D based on the depth branch

News

• 23/11/9. Thanks to slothfulxtx for adding depth backward pass to mean3D. I have put this optimization on the depth-mean3D branch.
