# class Matrix4x4

Matrix4x4 is used to represent and manipulate 4x4 transformation matrices, which can be either standard matrices, or homogeneous 4x4 matrices used to transform 3D homogeneous coordinates [x y z w]. The transformations are defined in row-major order.

# Static methods

Method Description
IsClassA Returns true if the class is a or is a descendant of the class named as the type parameter.
SafeCast SafeCast makes sure the input object is of a class that can be cast into spMatrix4x4, and if this is the case, returns the object cast into spMatrix4x4.
