Detailed Description

A Featureful 4-Space Matrix Class.

Matrix4f provides all the most basic functions of a Matrix class class: addition and subtraction, multiplication, scalar multiplication, inverse, transpose, and determinant. Additionally, it offers static creator functions for Zero and Identity matrices, and more advanced rendering-specific matrices as well.
