CG Projects

Introduction

This is the assignments for the Computer Graphics course, through which you'll learn how to:

• construct the simplest framework for a Computer Graphics program;
• display geometry and pixel data on the screen;
• use modern OpenGL API (3.3+);
• use GLSL, a Shading Language compatible with OpenGL;

This will help you understanding:

• the basic concepts in Computer Graphics:
  • geometry
  • lighting
  • texture
  • graphics pipleine etc;
• how GPU works to display a frame on the screen;

Basically, I follow the Learning OpenGL tutorials and refactor the old version assignments in an object oriented way. The students should have some knowledge of modern C++. Don't be panic if you haven't learnt C++ yet. You'll write no more than 20 lines of code for most of the assignments.
