Projections: Orthographic and Perspective

This lecture covers the transformation pipeline from 3D to 2D, including model, view, projection, and viewport transformations. It explains the setup of extrinsic and intrinsic camera parameters, the difference between parallel and perspective projections, and the use of homogeneous coordinates. The lecture also delves into the details of orthographic and perspective projections, including their matrix representations and frustum mapping. It concludes with viewport transformation and invariance properties under various transformations.
