Detailed Description

4x4 float matrix

• this matrix type is not designed for calculations
• it is designed for compact storage and transfer purposes only
  • use mat4 for linear math calculations, then copy to mat4f and
  • cast to const float * to transfer via glUniform:
    • glUniformMatrix4fv(location, 1, GL_FALSE, (const float *)mat4f(M));
