Slow training and no texture mesh

[Jonas7777777]

Hello, thanks for your excellent work!

Here I meet two problems mainly:

1. When I run original Gaussian Splatting on MIP NeRF 360_v2/kitchen scene, it can achieve around 25 it/s as showing as following.
   

But the traininng on GOF is slow, it takes totally more than two hours (3.5 it/s) for training of this scene as following

2. There is no teture on mesh, how can I configure and add the color on it?

System:
Linux 22.04
RTX 4090

Thanks in advance if someone solves it.
Jonas

Hi, I just added mesh texturing. Please pull the latest code and extract the mesh with --texture_mesh.

The training speed is not as fast as 3DGS since the current cuda code is not fully optimized. Will try to optimize it later.

Hi! thanks for your great project ! I use the latest code and make this mesh, it seems that the color of my mesh is the depth value. Can the color of the vertices be the real color or an approximation of the actual color?

Thanks for your quick response and update of source code!

When I run extract_mesh.py as following:
python extract_mesh.py -m ./exp_360/release/kitchen --iteration 30000 --texture_mesh

It seems the color of the vertices is not correct. Any explainations for this ? Thanks!

Hi, the textured mesh looks ok from my side. Could you try to test it on the lego scene in the nerf-synthetic dataset first?

Maybe you need to re-compile the cuda code.
