Differential Gaussian Rasterization with Depth and Accuracy Map

Gaussian Splatting Rasterizer

Install

pip install <path of this repo> -e

At gaussian_renderer/__init__.py, change some lines

### from diff_gaussian_rasterization import GaussianRasterizationSettings, GaussianRasterizer
from diff_gaussian_rasterization_depth_acc import GaussianRasterizationSettings, GaussianRasterizer

### rendered_image, radii, depth = rasterizer(
rendered_image, depth, acc, radii = rasterizer(

### ... and return dictionary

Notice

• We update and confirm backward with pytorch by refering diff-gaussian-rasterization, although some difference at preprocessCUDA() in cuda_rasterizer/backward.cu
