In addition to the Voronoi diagram and the Delaunay triangulation, the library also provides the convex hull, minimum and maximum spanning trees, and several other related geometric entities. as3delaunay is based on Steven Fortune's C implementation of his sweepline algorithm. Here is a demonstration program exercising the library's capabilities (Flash required). This is release 1.0 of as3delaunay, September 28, 2009. Some Links
Snowflake Template Patterns for young children to fold and cut As I was learning about all the different snow crystal classifications symbols I thought about applying a few to my folding pattern templates so that children and other interested parties could take a crack at making a snowflake based upon a scientific symbol. Snowflakes come in more than just the 6-sided variety, so I made formats for the 12, 2 and 3 sided as well as the more common 6 sided shapes.

Polygon map generation, part 2 In the previous blog post I described creating polygon island maps. Given random points, Voronoi diagrams with Lloyd relaxation produce a nice set of polygons. The polygons, their edges, and their corners can be represented as two related graphs.
