StippleGen was tested under 2.0b6; I have not tested it under 2.0b7, and we do know that there are changes that affect the compatibility with some of our other sketches.
For very large numbers of points, StippleGen is very slow. Depending on your particular application, you may be able to speed things up by breaking the image into smaller chunks that you render independently, or by running StippleGen repeatedly, with a lower number of points in each test.
For a much bigger speedup, I’m afraid that the ToxicLibs voronoi routines are likely the holdup; using a computer vision software package, for example OpenCV (which can interface to processing) might be able to create a very large improvement.
