First Generation -- Wireframes

Second Generation -- Shaded Solids

Third Generation -- Texture Mapping

Fourth Generation -- Programmability

Modern Graphic Pipeline

Application

• Simulation
• Input event handlers
• Modify data structures
• Database traversal
• Primitive generation
• Utility functions

Command

Geometry

Rasterization

Texture

Fragment

Display

Programmable Graphics Hardware

Vertex Shader

Pixel Shader

Multipass

• Render the scene or part of the geometry multiple times
• E.g. shadow map, shadow volume
• But also to get more complex shaders

GPU

Bottlenecks
