Preface Course Summary This course summarizes the best current techniques for simplifying complex polygonal surface models in order to accelerate rendering, speed network transmission, and conserve memory. The construction and use of multiresolution models that describe 3-D shapes at multiple levels of detail will be covered. Applications in CAD, Web publishing, geographic information systems, computer vision, and virtual reality will be discussed.
Course Objectives Attendees will learn techniques for simplifying complex models and building multiresolution models. The algorithms covered include methods for terrains, methods for manifolds (simple 3-D surface models), and non-manifold surfaces (any set of polygons). Attendees will learn about free and commercial software, how the best algorithms work, and about open research problems.
Course Prerequisites Understanding of 3-D geometry, simple polygon modeling techniques, and simple spatial data structures.
Intended Audience Users, developers, and researchers working with complex polygonal models.
Level Intermediate.
Course Notes The papers include previously published and forthcoming papers and technical reports, and notes written specially for this course. Material is grouped by speaker, with slides following papers. The printed notes and SIGGRAPH ’97 CD ROM contain identical material, except that some papers and slides on the CD ROM contain color images that appear in grayscale in the printed notes, and there is one set of slides on the CD ROM that does not appear in the printed notes.
