Asking about the normalization of both mesh and voxel grid

[DavidYan2001]

Dear authors,

Thanks for your interesting and helpful work! When I go through the code, I find that you provide a normalize_mesh function which actually normalizes the mesh into [-0.95, 0.95], not [-1, 1]. Am I right?

Btw, when you train the dense grid VAE, how to normalize the input points and voxelize them into grids?

Appreciate it if you could help with my questions, thanks a lot!

Thanks for your attention!

Yes, we will normalize the mesh into [0.95, 0.95]. When training the dense grid VAE, we divide the coordinates of the sparse voxels by the downsampling factor 8, and use the unique function to remove duplicate coordinates, obtaining the valid coordinates in the dense grid, which are then set to 1.
