Course Plan Focus on real-time rendering Follow the “pipeline” (see CG Overview ppt) Implement main ideas with OpenGL Review “pre-rendered” methods Create cool programs!
Reason: more detail and realism © Pixar On 1995 computer hardware Toy Story average frame took 2 hours to render On 2005 hardware Cars average frame took 15 hours to render despite 300x overall increase in compute power Reason: more detail and realism
Changes … More work to do Finding Nemo and Finding Dory Hank: 2 years to create one scene! Comparison Side-by-side scene Some details
