Modifications

• use spherical harmonics match e3nn as used in MVSplat.
• add depth rendering implemented in depth-diff-gaussian-rasterization.
• add importance score for each 3D gaussian based on its contribution to rendering.
• add opacity rendering in forward pass.
• add n_touched to count the number of pixels each Gaussian contributes to

Differential Gaussian Rasterization

Used as the rasterization engine for the paper "3D Gaussian Splatting for Real-Time Rendering of Radiance Fields". If you can make use of it in your own research, please be so kind to cite us.
