(Course Outline) 1. Introduction and basic OpenGL (today) 6. Discrete Techniques (texture etc.) 2. Graphics Programming (basic OpenGL, 7. Object Hierarchies (scene graphs) ( 2 × ) input and interaction) ( 2 × ) 8. Curves and Surfaces 3. Geometric Objects and Transformations ( 2 × ) 9. Implementation of a Renderer 4. Viewing (3D and perspectives) 5. Shading (light and matter)

Computer Graphics (Introduction, Basic OpenGL), ((23)) � 2000–2008, Thilo Kielmann c 10 Outline for today • Graphics systems architectures • High-end graphics systems Computer Graphics (Introduction, Basic OpenGL), ((23)) � 2000–2008, Thilo Kielmann c 11 Graphics Systems Architectures
