Have you ever tried the result of svox2 of your implementation with offical svox2? I try with grid size=16 and downsample lego with scale=8, however... I dont reach the result as good as offical svox2. Have u ever try it?

Hi:
I I am very interested in your simple implementation of Plenoxels, although the speed and quality are not as good as the original project, it is good for getting started quickly.
But I have a problem in your code, in VoxelGrid.py file, there is a class method：def render_rays(self, ordir_tuple, N_points, inv_depth=1.2):
distances = 10 *
torch.sqrt((ordir_tuple[1]**2).sum(1,
keepdim=True))/inv_depth/(N_points-1)
This code is supposed to set the distance between each sample point on the ray, but why are you multiplying by 10, and what does inv_depth mean?
Looking forward to your answer.
