class sknano.core.geometric_regions.Sphere(center=None, r=1)

Geometric3DRegion for a sphere.

New in version 0.3.0.

Parameters:

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 $r$

Attributes

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.
