RhinoNurbsSurface

class compas_rhino.geometry.RhinoNurbsSurface(*args, **kwargs)[source]

Bases: RhinoSurface, NurbsSurface

Class representing a NURBS surface.

Attributes

• points (list[list[Point]]) – The control points of the surface.

• weights (list[list[float]]) – The weights of the control points.

• u_knots (list[float]) – The knot vector, in the U direction, without duplicates.

• v_knots (list[float]) – The knot vector, in the V direction, without duplicates.

• u_mults (list[int]) – The multiplicities of the knots in the knot vector of the U direction.

• v_mults (list[int]) – The multiplicities of the knots in the knot vector of the V direction.

• u_degree (int) – The degree of the polynomials in the U direction.

• v_degree (int) – The degree of the polynomials in the V direction.
