gs model.py:Why did you comment out "xyz" and "opacity" here?

[Gxt2002]

Why did you comment out "xyz" and "opacity" here? This will cause an error later due to the missing properties. Additionally, I am very interested in your work and have some other questions. Could we communicate? Here is my contact information:1328236619@qq.com

Thanks for your interest on our work! We set the centers of gaussians to the sampled points from the mesh surfaces. The reason we do not learn the center locations is that the surface points from GT meshes are already suitable geometries for 3DGS. You can refer to the supplementary for more details on fitting 3DGS.

We also found that simply set the opacity to a constant will lead to stable gaussian splattings since we already have the suitable GS geometry. You can also try to learn the opacities and xyz and set them to the predicted ones.

So does this mean we need to comment out the Densification part to avoid errors in the code?
