Skeletal mesh

In response to this discussion:

I am posting my definition for generating an open foam mesh.

(I didn't post back at the time because there were some troubles with weaverbird back then and I was having to use some ugly workarounds, but now that is all fixed)

To sum up the approach -

take a random cloud of points

generate the 3d voronoi

scale the edges of the cells towards their centres, and also towards the centres of the faces.

connect these 2 sets of scaled edges with mesh quads and join

cull some of the outer faces

subdivide and smooth with weaverbird

(In the video there were some other variations on the smoothing/relaxation, both of the initial point positions and the final mesh, using hoopsnake and/or kangaroo)

We are talking about Everest, I guess.

Does anybody know if you would potentially be able to control the density of the pattern with 3d attractor points?

I tried to do so but failed miserably, or either the only thing that changes is the thickness of the mesh.
