eval_bspline_surface — 3D freeform op

• Data kinds: bspline_surface × image2d × image2d → image2d

• Call: import bspline_surf; bspline_surf.eval_bspline_surface(tck, x, y, grid=False) (or ops3d.get("eval_bspline_surface"))

Usage

Evaluate a fitted surface tck (bisplev). Two modes: scattered points (the default) or a grid.
