SphericalSurface

class compas.geometry.SphericalSurface

Bases: Surface

A spherical surface is defined by a radius and a frame.

Parameters:

radiusfloat

The radius of the sphere.

frameFrame

The frame of the sphere.

namestr, optional

The name of the surface.

Examples

>>> from compas.geometry import Frame
>>> from compas.geometry import SphericalSurface
>>> frame = Frame([0, 0, 0], [1, 0, 0], [0, 1, 0])
>>> sphere = SphericalSurface(1.0, frame)
