[vtkusers] "Filling" parts of a volume that are "inside" a set of polyhedra

[Elvis Stansvik]

Hi all,

I have a set of points describing multiple convex polyhedra. The
polyhedra are for the most part disjoint in space, but they may
intersect slightly in some places.

I need to create an empty voxel volume (all scalars 0), and then
"fill" the voxels that are inside one (or several) of the polyhedrons
with some Perlin noise. I also have access to normals for the faces
constituting the polyhedra, if necessary.

Finally, I also have a single separate polyhedron (non-convex this
time), and as a finishing step, I'd like to fill the voxels that are
inside this polyhedron with a constant scalar value.

Can VTK help me here?

As this is new territory for me as far as VTK goes, any
pointers/advice on how to go about it would be much appreciated.

Cheers,
Elvis
