Reflectance and texture of real-world surfaces
Kristin J. Dana, Bram van Ginneken, Shree K. Nayar, Jan J. Koenderink
Pages: 1-34
DOI: 10.1145/300776.300778
In this work, we investigate the visual appearance of real-world surfaces and the dependence of appearance on the geometry of imaging conditions. We discuss a new texture representation called the BTF (bidirectional texture function) which...

Combining constructive and equational geometric constraint-solving techniques
R. Joan-Arinyo, A. Soto-Riera
Pages: 35-55
DOI: 10.1145/300776.300780
In the past few years, there has been a strong trend towards developing parametric, computer-aided design systems based on geometric constraint solving. An effective way to capture the design intent in these systems is to define relationships...

Two methods for display of high contrast images
Jack Tumblin, Jessica K. Hodgins, Brian K. Guenter
Pages: 56-94
DOI: 10.1145/300776.300783
High contrast images are common in night scenes and other scenes that include dark shadows and bright light sources. These scenes are difficult to display because their contrasts greatly exceed the range of most display devices for images. As a...
