    This document outlines topics covered in three units on 3D computer graphics: Unit 3 covers 2D and 3D transformations, projections, viewing, and the z-buffer algorithm. Unit 4 discusses lighting models, vector calculations, shading, rasterization, clipping, and hidden surface removal. Unit 5 focuses on animation, tree data structures, parametric curves and surfaces, B-splines, scene graphs, and rendering curves and surfaces in OpenGL.
