45: Advanced Issues in Level of Detail
Tuesday, Full Day, 8:30 am - 5 pm
Room 502B
Level
of Detail (LOD) methods have been established as crucial
tools for managing scene complexity in interactive 3D
graphics. This advanced course addresses current research,
including LOD error metrics, appearance-preserving simplification,
variable-precision rendering, controlled reduction of
topology during simplification, memory-coherent simplification,
and view-dependent LOD. It also explores related questions
in perceptual psychology: What degradation of detail will
be perceptible? What tradeoff between fidelity and frame
rate is appropriate for different tasks?
Prerequisites
Knowledge of the basic LOD concept and experience with
interactive graphics systems. Some experience with LOD.
A desire to become a sophisticated LOD user.
Topics
LOD creation: appearance-preserving simplification, parallel
LOD computation, controlled topology reduction. Alternative
LOD frameworks: dynamic and view-dependent LOD, memory-coherent
and out-of-core LOD. Underpinnings: classifying LOD error
metrics, perceptual analysis of degradation in detail,
the fidelity/ performance tradeoff, other perceptual issues.
