i mean something like:
https://github.com/mikedh/trimesh/issues/526

Should work with report surface, notice that this is not triangles, assumption is this is a fixed sampling of the surface, sample size is the numpy array matrix and the sample value (i.e. Z ) is the value on the matrix. This means that if you have a set of mesh triangles , you have to projects and sample it.
I think this is what you are after https://trimsh.org/trimesh.voxel.base.html?highlight=matrix#trimesh.voxel.base.VoxelGrid.matrix

3d scatter points:
https://github.com/allegroai/trains/blob/master/examples/manual_reporting.py#L53

Which one of those? the 3d ball dots or the 3d face mesh?

Thanks ! I will try!
