Thanks Laijiren! Indeed some of our existing NURBS/BREP infrastructure would definitely be of great use here. They're used to evaluate trimming curves in the 2D u/v domain of NURBS surfaces during raytracing and are carved up similarly to what I described. You'd have to promote/convert the Bezier curves to NURBS curves, but that isn't difficult. Might even be an existing openNURBS routine to do it for you. Cheers!
