Then it’s handy that Dave already implemented it in the (free) Grasshopper plugin (provided in the link above, where he references the same paper)
Just update a link that at the moment of writing this comment wasn’t easy to find:
My name is Sheyla. I am working with pointools doing 3d modelling. Recently I got a new computer and I installed Rhino 5 32bit and installed pointools plug-in and by using toolbar I open its tools however, I am having a problem to make this run.
The message is Error loading\PointoolsVortexAPI.dll
Please someone can help me with it
Maybe PointTools needs 64 bit Rhino 5 to run?
