Previous: Rendering Primitives
A number of basic algorithms are needed:
Convert representations of primitives from one
coordinate system to another.
- Clipping/Hidden Surface Removal:
Remove primitives and parts of primitives that are not
visible on the display.
- Rasterization: Convert a projected screen-space primitive
to a set of pixels.
Later, we will look at some more advanced algorithms:
- Picking: Select a 3D object by clicking an
input device over a pixel location.
- Shading and Illumination:
Simulate the interaction of light with a scene.
Simulate movement by rendering a sequence of frames.
