Constraint-based approach for automatic hinting of digital typefaces
Ariel Shamir
Pages: 131-151
DOI: 10.1145/636886.636887
The rasterization process of characters from digital outline fonts to bitmaps on displays must include additional information in the form of hints beside the shape of characters in order to produce high quality bitmaps. Hints describe...

Perceptually-driven decision theory for interactive realistic rendering
James A. Ferwerda, Reynald Dumont, Fabio Pellacini
Pages: 152-181
DOI: 10.1145/636886.636888
In this paper we introduce a new approach to realistic rendering at interactive rates on commodity graphics hardware. The approach uses efficient perceptual metrics within a decision theoretic framework to optimally order rendering operations,...

Planning biped locomotion using motion capture data and probabilistic roadmaps
Jehee Lee, Min Gyu Choi, Sung Yong Shin
Pages: 182-203
DOI: 10.1145/636886.636889
Typical high-level directives for locomotion of human-like characters are useful for interactive games and simulations as well as for off-line production animation. In this paper, we present a new scheme for planning natural-looking locomotion of a...

An efficient instantiation algorithm for simulating radiant energy transfer in plant models
Philippe Dereffye, François X. Sillion, Frédéric Blaise, Cyril Soler
Pages: 204-233
DOI: 10.1145/636886.636890
We describe a complete lighting simulation system tailored for the difficult case of vegetation scenes. Our algorithm is based on hierarchical instantiation for radiosity and precise phase function modeling. It allows efficient calculations both in...

Image-based reconstruction of spatial appearance and geometric detail
Hendrik P. A. Lensch, Wolfgang Heidrich, Hans-Peter Seidel, Michael Goesele, Jan Kautz
Pages: 234-257
DOI: 10.1145/636886.636891
Real-world objects are usually composed of a number of different materials that often show subtle changes even within a single material. Photorealistic rendering of such objects requires accurate measurements of the reflection properties of each...

Errata: ACM SIGGRAPH 2002 Papers
Stephen N. Spencer
Pages: 258-258
DOI: 10.1145/636886.636892
