Sphere

class compas.geometry.Sphere(point, radius)[source]

Bases: compas.geometry.shapes._shape.Shape

A sphere is defined by a point and a radius.

Parameters
  • point (compas.geometry.Point list of float) – The center of the sphere.

  • radius (float) – The radius of the sphere.

Attributes
  • point (compas.geometry.Point) – The center of the sphere.

  • radius (float) – The radius of the sphere.

  • center (read-only) (compas.geometry.Point) – The center of the sphere.

  • area (read-only) (float) – The surface area of the sphere.

  • volume (read-only) (float) – The volume of the sphere.

Examples

>>> from compas.geometry import Point
>>> from compas.geometry import Sphere
>>> sphere1 = Sphere(Point(1, 1, 1), 5)
>>> sphere2 = Sphere((2, 4, 1), 2)
>>> sphere3 = Sphere([2, 4, 1], 2)

Methods
