Poriangle: POlygon + tRIANGLE

Triangle Polygon Editor

Free

There's a technique called Delaunay triangulation used in computational geometry. While it has plenty of practical applications, let's skip the technical stuff—filling shapes with triangles just looks cool. Poriangle is a shape editor that lets you draw any shape and fill it with Delaunay-style triangles. Draw, experiment, and have fun creating your own designs.
