hi There, Im trying to deform a texture using a grid of control points that initially are a uniform grid (texture is not deformed) and one can move control points to deform texture (a map between the rectangle and the new 2d surface) Seems like a simple thing. However, after I create the surface, …

Hi @pablo.cael , Does this help? import Rhino import scriptcontext as sc def create_deformable_plane(corners, u_degree, v_degree, u_points, v_points): p0, p1, p2, p3 = corners domain0 = Rhino.Geometry.Interval(0.0, p0.DistanceTo(p1)) domain1 = Rhino.Geometry.Interval(0.0, p0.DistanceTo…

Hi Dale, thanks for the reply and sorry for the delay. Unfortunatelly, Im not sure why I was not able to make it work, as I try to use it with degree 3 and configurable number of points. I want each control point to be movable and independent so I need to add control points in the grid. I have trie…

Hi @pablo.cael , Did you try my Python script? Did you try porting it to C++? – Dale

Hi Dale, first of all, thanks a lot for the replies so far. I have tried your example in c++. It seems to retrieve the correct points at extremes of parametrization t in [0,1], u in [0,1]. But I havent checked more since I actually need a grid of controlpoints that can be manipulated, and not a lin…

Maybe its easier to just implement a tensor product of splines in my case, since I actually want a spline surface so each control point passes through the data. ;}

Hi @pablo.cael , Sorry, but it is unclear to me what you want. Can you use Rhino command(s) to produce the surface? If so, can you post the geometry? Thanks, – Dale
