A question about the dense point clouds.

[ShilangChen1011]

This is a good job. I have some questions while reading the paper and the code. The paper says that it can generate dense point clouds, but I don’t see any direct generation of dense point clouds in the code. There is a part about generating mesh. Is the dense point cloud you mentioned the same as the mesh you generated? Thanks!

Hello, you can analyze the code within the "update_density_grid_nerf" function by following this link:

update_density_grid_nerf

This function determines which voxels in the density grid should be considered as a surface. It then checks whether the voxel satisfies the specified threshold and samples a point from the voxel to generate a dense point cloud.

You can find this part of the code here:
