Shear.from_angle_direction_plane

classmethod Shear.from_angle_direction_plane(angle, direction, plane)
Parameters

  • angle (float) – The angle in radians.

  • direction (compas.geometry.Vector or list of float) – The direction vector as list of 3 numbers. It must be orthogonal to the normal vector (i.e. it must lie in the shear plane).

  • plane (compas.geometry.Plane or (point, normal)) – The shear plane defined by a point and normal.

Raises

ValueError – If the shear direction does not lie in the shear plane.

Returns

Shear – The shear transformation object.

Examples

>>> angle = 0.1
>>> direction = [0.1, 0.2, 0.3]
>>> point = [4, 3, 1]
>>> normal = cross_vectors(direction, [1, 0.3, -0.1])
>>> S = Shear.from_angle_direction_plane(angle, direction, (point, normal))
