Contains three scripts to create random polka dot textures.
makesimple.py creates an image containing polka dots.
makepolygon.py creates an image containing polka dots that are bounded by a polygon. The example uses a regular octagon.
makesherical.py crates a texture containing the cylindric projection of a sphere covered in randomly distributed polka dots. This texture can then be used to render a correctly textured sphere by reprojecting the texture using a cylindric projection.
