Modern SG Library Can Provide Optimized Runtime:
Akin to high level optimizing compiler: platform independent API w/ hardware optimized driver implementation
Written by professionals who know algorithms and hardware
As hardware supports geometry and lighting (becomes more complex), more of the rendering pipeline will be handled by library/drivers, less by application
More than a retained data structure and more part of application: OO, traversers, renders, etc.
