Long overdue submission to food4Rhino, has a few bugs which I am no longer able to fix but some of the tools might come in useful.
In particular, the tools have been coded for multi-threaded processing (simple brainless multi-threading) and as such can run a little faster for larger point clouds.
Included is an example file to showcase its use.
