Outline • Milestone 1 • General Remarks • Huebner’s Presentation at GDC 2003 • NVIDIA performance tools at GDC 2006
Milestone 1 • Next Thu, Feb 12th • Set up schedule for 30 min individual discussions
General Remarks • Gaming environment requirements • Constant frame rate • Main memory utilization • Instantiations • Scalable platforms • Bottlenecks (fill rate versus triangle rate) • Average triangle size • “It is also worth noting that game developers are notoriously practical engineers when it comes to new techniques.” page 183
Modeling Practices • Interaction between artistic elements of generating models and LOD options
LOD for Games • Retain two broad categories • Continuous • Discrete
All About Performance • Triangle strips • Multiple texture maps in a texture map composite • Shared and separate vertices • Memory management • Vertex cache coherence • Shadow LOD • Imposters • Prerendered texture imposters • Geometric imposters
