Hello Al,

most of the functions are already implemented. Have a look in basicfunctions.js or in the litegraph.js (Max has thought of everything!). Only missing: wrap it in nodes. We can use pointarray as the base. Set scale to 0 it's a displacement vector:-). Scale to 1 it's a local vector ->arraypoint (Homogeneous coordinates). You've done the vector math stuff manually with the splitPts, (chapeau - a lot of work ) but yes we should make nodes for that. It will take a while and I have to think about some details, but it's possible.
Thanks for the impressive example!

Have a nice evening
Karsten
