Transformations

The Transform class describes linear transformations and is accepted wherever a transformation is used, such as transform(). The functions on this page transform points and vectors directly.

Transform(*args, **kwargs)	Describes linear transformations via a 4x4 matrix.
core.utilities.axis_rotation(points, angle)	Rotate points by angle about an axis.
