Sounds similar to drawing intersecting cones at each point, which is a pretty common method I think. For example: http://alexbeutel.com/webgl/voronoi.html http:

For example: http://alexbeutel.com/webgl/voronoi.html http://alexbeutel.com/webgl/voronoi.html A nice thing about that is if you draw cones with just 4 sides (so, pyramids..) you get a manhattan distance voronoi pattern (or something that looks very similar at least).
