<br>
I have a set of points describing multiple convex polyhedra. The<br>
polyhedra are for the most part disjoint in space, but they may<br>
intersect slightly in some places.<br>
<br>
I need to create an empty voxel volume (all scalars 0), and then<br>
"fill" the voxels that are inside one (or several) of the polyhedrons<br>
with some Perlin noise. I also have access to normals for the faces<br>
constituting the polyhedra, if necessary.<br>
<br>
Finally, I also have a single separate polyhedron (non-convex this<br>
time), and as a finishing step, I'd like to fill the voxels that are<br>
inside this polyhedron with a constant scalar value.<br>
<br>
Can VTK help me here?<br>
<br>
As this is new territory for me as far as VTK goes, any<br>
pointers/advice on how to go about it would be much appreciated.<br>
<br>
Cheers,<br>
Elvis<br>
