Voronoi test

Left: original Voronoi model composed of particles in walls (blue) and the spine (red).
Center: pixels identified by the Spine method as walls (blue) and filaments (red). Pixels in filaments were dilated by one pixel across for visualization purposes.
Right: particles recovered inside walls (blue) and filaments (red). We also show the particles that were erroneously identified (green). The box shown here contains 1/64 of the original box volume.
Rendering done with Blender.

Spine animation

This is a movie of a volume rendering showing the spine (filaments + clusters) in yellow and later the walls in green. Note how the walls define the boundaries between voids.
