Geometry

Description
In this lecture, we take a close look at the geometry stage of the graphics pipeline: transformations, homogeneous coordinates, the OpenGL lighting model, primitive assembly, clipping, and culling. We also look at ways to save computation and bandwidth: vertex arrays, vertex caches, and geometry compression. [Note: This lecture spills over into the "rasterization" lecture.]

In our final content lecture, we look at how to parallelize the graphics pipeline. What is challenging about parallelizing the GPU? What are the ways we could parallelize it? We discuss the sorting taxonomy of parallelism strategies, look at different ways to communicate within a multi-node...

We turn away from a fixed-function graphics pipeline and explore what we can do with a user-programmable pipeline, where not only pipeline stages but also the structure of the pipeline can be customized. We look at Reyes, delay streams, and the programmable culling unit.
