Hey, it only takes one hour to train the same data 30,000 times with the original 3DGS. 微信截图_20241019181529

Hi, maybe more gaussians are used. Could you try to remove this line https://github.com/autonomousvision/mip-splatting/blob/main/scene/gaussian_model.py#L504 and this line https://github.com/autonomousvision/mip-splatting/blob/main/scene/gaussian_model.py#L480

It works, meanwhile PSNR decreased about 0.2？

The new densification improves NVS quite a lot. The other option is to keep this new densification metric but use high threshold to remove more Gaussians. Use 0.05 instead of 0.005 here: https://github.com/autonomousvision/mip-splatting/blob/main/train.py#L163.
