public Class Matrix4

extends Object
Class Inheritance
Imports
com.jogamp.opengl.GLException, com.jogamp.opengl.fixedfunc.GLMatrixFunc, com.jogamp.opengl.util.PMVMatrix
Simple float array-backed float 4x4 matrix exposing FloatUtil matrix functionality in an object oriented manner.

Unlike PMVMatrix, this class only represents one single matrix without a complete GLMatrixFunc implementation, allowing this class to be more lightweight.

Implementation is not mature - WIP and subject to change.
