Cuboid¶
-
class
sisl.shape.
Cuboid
(v, center=None)[source]¶ A cuboid/rectangular prism (P4)
- Parameters
- vfloat or (3,) or (3, 3)
vectors describing the cuboid, if only 3 the cuboid will be along the Euclidean vectors.
- center(3,), optional
the center of the cuboid. Defaults to the origo.
Examples
>>> shape = Cuboid([2, 2.2, 2]) >>> shape.within([0, 2.1, 0]) False >>> shape.within([0, 1.1, 0]) True
Attributes
The geometric center of the shape
The lengths of each of the vector that defines the cuboid
Return the origin of the Cuboid (lower-left corner)
Methods
__init__
(self, v[, center])Initialize self.
