New in version 0.3.0.


center : array_like, optional

Either a 3-tuple of floats or an instance of the Point class specifying the \((x,y,z)\) coordinates of the Sphere center.

r : float, optional

Sphere radius \(r\)


center Sphere center point \((h, k, l)\).
centroid Alias for center.
fmtstr Format string.
measure Alias for volume, which is the measure of a 3D geometric region.
r Sphere radius, \(r\).
volume Sphere volume, \(V=\frac{4}{3}\pi r^3\).


center_centroid() Center centroid on origin.
contains(point) Test region membership of point in Sphere.
