Linear Algebra

The maths you actually need to put a 3D point on a 2D screen, written out so I do not have to re-derive it.

• 3D Rotations with matrices
• Homogeneous 4x4 matrices
• Rotate a 3D point (x, y, z) around each axis
• Rotate a point (x, y) around a center (cx, cy) by angle θ (in radians)
• Transformation Matrices
