Overview

This is an introductory course in Computer Graphics using OpenGL with emphasis on the theory and practice. Core topics of discussion include: mathematics for computer graphics, transformations, viewing geometry, literature behind color, illumination and rendering. We will use PyOpenGL + GLFW to experience the theory in action.

Learning Outcomes

The idea of fixed vs modern graphics pipeline.
The essential mathematical background for computer graphics.
Idea of shaders and basic shading language.
Viewing transformations (2D and 3D).
Theory behind curve represntaion.
Modelling 3D objects (color, illumination, rendering)
Application of computer graphics in Augmented Reality
