This project is based off the Voro++ project. That code was modified and extended to take an input STL and generate an output STL which is the same form as the input STL, but filled with a cellular voronoi pattern.

For more information about running the script, see sw/readme.txt

For example, for this input STL (in examples/bunny.stl),

ViewSTL examples/bunny.stl

The rendered output STL,

ViewSTL sw/out.stl-0.stl

Using 'ViewSTL' (provided in this project) to view both input and output STL at the same time,

ViewSTL examples/bunny.stl sw/out.stl-0.stl

Then you print that output STL for fun!
