Chapter 7
- Rendering Systems
2
Rendering Systems
- Visual
- Aural
- Haptic
3
Visual Rendering Systems
- aka Computer Graphics
- Software rendering vs. Hardware rendering
- Object representation schemes
- Geometrically based (polygons, NURBS, CSG)
- Non-geometric forms (volumetric rendering,
particle systems)
4
- Geometrically based internal representations
- Polygons
- Constructive Solid Geometry (CSG)
- Non-Uniform Rational B-Splines (NURBS)
- Other representations are often converted to
polygons for hardware rendering
