Robust View-Dependent Simplification for Very Large-Scale CAD Visualization

Author:Luebke, David, Department of Computer ScienceUniversity of Virginia

View - dependent simplification (VDS) is a novel polygonal simplification algorithm uniquely suited to the interactive visualization of very large - scale CAD datasets. VDS adjusts the simplification continually according to View-dependent parameters such as the viewpoint position and orientation. As a result, objects can span several levels of detail, degrading smoothly from high fidelity where necessary to low fidelity where possible. VDS is also global, able to process the entire database without first decomposing the environment into individual objects. The resulting system enables interactive display of Very complex polygonal CAD models consisting of thousands of parts and millions of polygons. VDS supports various preprocessing algorithms and various View~dependent criteria, providing a general framework for dynamic view-dependent simplification.
