How to Convert Meshes Object to Voxels

❓ Converting Meshes to Voxels

I have a Meshes object and want to convert it to voxels (really just a 3D occupancy grid). Is this operation available somewhere? I want to use it as an input for a neural network. I don't need any texture or color info--just whether the space is occupied or not.

Thanks a lot!

Hi, I have the same question and could not find such functionality in Pytorch3d. What did you end up using?

This would occasionally be useful to me as well. I found some reference implementations that could be used, like this one in trimesh, and a few papers.

This would also be useful to me.
