sknano.core.geometric_regions.Cube

class sknano.core.geometric_regions.Cube(center=None, a=1)

Geometric3DRegion for a cube.

New in version 0.3.0.

Cube represents the region \(\left\{\{c_i\pm\frac{a}{2}\}|a>0\forall i\in\{x,y,z\}\right\}\).

Parameters:

center : array_like, optional

The \((x,y,z)\) coordinate of the axis-aligned cube center \((c_x, c_y, c_z)\).

a : float, optional

Side length \(a\) of axis-aligned cube.

Notes

Calling Cube with no parameters is equivalent to Cube(center=[0, 0, 0], a=1).

Attributes

a	Side length \(a\) of the axis-aligned cube.
center	Center point \((c_x, c_y, c_z)\) of axis-aligned cube.
centroid	Alias for center.
fmtstr	Format string.
measure	Alias for volume, which is the measure of a 3D geometric region.
volume	Cube volume, \(V=a^3\).

Methods

center_centroid()	Center centroid on origin.
contains(point)	Test region membership of point in Cube.
rotate([angle, axis, anchor_point, ...])	Rotate GeometricRegion points and vectors.
todict()	Returns a dict of the Cube constructor parameters.
translate(t[, fix_anchor_points])	Translate GeometricRegion points and vectors by Vector t.
