hi,
id like to control the input points for a vornoi noise in shader with a pointcloud from SOP. i guess i need to use the pcopen to get to the pointcloud.
but what data to fetch and how to feed it in for the voronoi. is it even possible with the existing node or should it be done manually in vex?
cheers!

i don't believe its possible to feed points into the vornoi noise function, but you can create the functionality of vornoi noise just with the point cloud lookups
here's an example of doing some vornoi type stuff with point clouds
edit: this shader produces an infinite discontinuity at the voronoi borders. i don't think this would cause problems for the nearst 1 dist and the nearest 2 dist, but antialising the random color one (particularly for micropoly rendering) might take some doing
