OpenGL Graphics Pipeline

The OpenGL graphics pipeline is a sequence of processing steps that converts 3D vertex coordinates and data into a 2D colored image on your screen. It handles everything from transforming 3D models and applying lighting to rasterizing shapes and calculating individual pixel colors.

3D Rotations

A basic 3D rotation (also called elemental rotation) is a rotation about one of the axes of a coordinate system.

Rotation Matrix and Rotation Vector

A rotation vector is a convenient and most compact representation of a rotation matrix (since any rotation matrix has just 3 degrees of freedom).
