Number of gaussian and shape

[kelo020304]

I am really confused : 1)why number of gaussian sphere seems little and achieve such dense voxel representation 2) why all gaussian seems a sphere rather than Ellipsoid, I think this do not take advantage of gaussian representation.

Me too, did you figure out what's going on?

Which part of the code did you use to generate this? Also, given this, it seems redundant to optimise scale and rotation if the Gaussians remain spherical, due to spheres being invariant under rotation about their center point.

NO，what do you think about it

I just use visualize.py to get this pic with 25600 gaussian, and I tried to close the restrict_xyz, but the model do not converge on 4090 for 3days

Have you met this problem and how did you to solve it?

this

I just use one 4090 and I can train 25600 version

oh thanks, I will try again
