Overview of 2D & 3D Pipelines
What are Pipelines?
Are the fundamental concept around which graphics systems are based
Represent conceptual models
Describe the interaction and the flow of data for all functions
Illustrate how the applications can create, save, modify, draw, and display pictures
Illustrate how applications can create pictures
Illustrate the use of functions to set up the environment
Illustrate how the environment affects pictures being created
Illustrate the interactions and the relationships between functions
Modeling
Modeling transformations...
...allow objects to be defined in their own coordinate system
Through modeling...
...objects are transformed into world coordinates by scaling, rotation, and/or translation
This allows all objects to initially be defined as centered around the origin...
...and then modeling transformations can position, orient, and scale them into their correct geometric relationships
This stage in the pipeline is independent of the display characteristics
