Things to note when reproducing the code

[zxy-bjtu]

1. It seems that submodules/diff-gaussian-rasterization is different from original code, so you'd better to recompile it using:

   cd submodules/diff-gaussian-rasterization
   python setup.py install && pip install .

2. The version of opencv-python cannot be so high (example, 4.10)， 4.6.0.66 will be ok.
3. You must mkdir 'test' in working directory, or you'll get error.
4. You need to put nn_idx on the cpu on l.236 of general_utils.py as the issues #15 , or you'll get error when you extract mesh：

   nn_idx = nn_idx[0].cpu()
