about

nx_bezier_patch_gate.nx -- proves the parametric spline surface (bicubic Bezier patch): corners INTERPOLATED, interior control points PULL a smooth bulge (hand-exact 9/16*H at the center), tessellated watertight, and a flat-net NEG-CONTROL yields a flat surface. Answers the census GAP "NURBS / parametric spline surfaces". license_tier: ORIGINAL expect_exit: 0
