  Description

Unlike the datatypes you are used to, these datatypes are stored internally and referenced by an index value. The MATRIX4 datatype contains sixteen float values representing a 4x4 matrix of data. This is a typical 3D matrix used in many advanced 3D calculations. You can imagine the grid headed with columns X,Y,Z,W by rows X,Y,Z,W.
