When my office mate Benno asked me to come up with a setup to turn a bunch of hexagons into a voronoi cell pattern, it came to my mind that there is a wide variety of techniques in Houdini to achieve such a transition effect: Using built-in nodes vs. using VEX.
One of the great things about the Houdini community is that we’re always confronted with clever questions and with clever answers too. “How do I color strands using an image’s color palette?” was the comment on Vimeo that led to this setup. Yet when talking about coloring polylines we also need to discuss rendering them.
