I want to generate a binary mask that has ones for all pixels inside and zeros for all pixels outside a volume. The volume is defined by the convex hull around a set of 3D coordinates (<100; some of the coordinates are inside the volume).

I can get the convex hull using CONVHULLN, but how do I convert that into a binary mask?

In case there is no good way to go via the convex hull, do you have any other idea how I could create the binary mask?

Hi All! I'm having an issue interacting between Matlab and .NET. I've managed to call .NET methods from Matlab code and vice versa.

I am attempting to do this within CGAL. From a 3D point cloud, find the convex hull, then loop over the finite facets of the convex hull and print each facet's vertices.

I guess that my problem is related to "convex hull", but no the same. All shapes in the drawing are rectangles with same width and height. Many are adjacent to each other.
