Detailed Description

4x4 matrix. DirectX-compliant, ie row-column order, ie m[Row][Col]. Same as: m11 m12 m13 m14 first row. m21 m22 m23 m24 second row. m31 m32 m33 m34 third row. m41 m42 m43 m44 fourth row. Translation is (m41, m42, m43), (m14, m24, m34, m44) = (0, 0, 0, 1). Stored in memory as m11 m12 m13 m14 m21...

Multiplication rules:

[x'y'z'1] = [xyz1][M]

x' = x*m11 + y*m21 + z*m31 + m41 y' = x*m12 + y*m22 + z*m32 + m42 z' = x*m13 + y*m23 + z*m33 + m43 1' = 0 + 0 + 0 + m44
