Surface

class compas.geometry.Surface(*args, **kwargs)[source]

Bases: Geometry

Class representing a general surface object.

Parameters

name (str, optional) – The name of the surface.

Attributes

• u_domain (tuple[float, float], read-only) – The parameter domain of the surface in the U direction.

• v_domain (tuple[float, float], read-only) – The parameter domain of the surface in the V direction.

• is_u_periodic (bool, read-only) – Flag indicating if the surface is periodic in the U direction.

• is_v_periodic (bool, read-only) – Flag indicating if the surface is periodic in the V direction.
