给定 3D 中的一个点和一个体素网格，找到相应的体素

Question

I am a newbie in 3D computer vision, currently solving the following problem in Python:

I have a voxel grid in 3D and a random point in 3D. I want to find which voxel this point falls into. Is there some simple way how to do this?

More advanced question is - is there some way to interpolate between voxels? Meaning if a point is near the boundary between two voxels, can I get the corresponding voxels and some weights?

Thanks!

Answer 1

Floor every dimension of the point and multiply by voxel size for the exact voxel you're looking for
