Performance issue of the provided Gaussian model. #2

Hi, I've tested the provided pre-trained model on Rubble. It seems the performance is pretty weird. The PSNR is 14dB, which is quite low. image image

I think you installed diff-gaussian-rasterization from the original repo, not our repository. Gaussians near the target camera are not rendered in your rendered image, and this is because the original diff-gaussian-rasterization ignores such Gaussians. https://github.com/graphdeco-inria/diff-gaussian-rasterization/blob/59f5f77e3ddbac3ed9db93ec2cfe99ed6c5d121d/cuda_rasterizer/auxiliary.h#L154

We modify it in our repo. https://github.com/DensoITLab/Fed3DGS/blob/9d9ca8d5429ed3e86c284fb5406ed941642fe768/gaussian-splatting/submodules/diff-gaussian-rasterization/cuda_rasterizer/auxiliary.h#L154

Please reinstall diff-gaussian-rasterization from our repo.
