Islamic star patterns in absolute geometry
Craig S. Kaplan, David H. Salesin
Pages: 97-119
DOI: 10.1145/990002.990003
We present Najm, a set of tools built on the axioms of absolute geometry for exploring the design space of Islamic star patterns. Our approach makes use of a novel family of tilings, called "inflation tilings," which are particularly well...

Real-time rendering of translucent meshes
Xuejun Hao, Amitabh Varshney
Pages: 120-142
DOI: 10.1145/990002.990004
Subsurface scattering is important for photo-realistic rendering of translucent materials. We make approximations to the BSSRDF model and propose a simple lighting model to simulate the effects on translucent meshes. Our approximations are based on...

Pop-up light field: An interactive image-based modeling and rendering system
Heung-Yeung Shum, Jian Sun, Shuntaro Yamazaki, Yin Li, Chi-Keung Tang
Pages: 143-162
DOI: 10.1145/990002.990005
In this article, we present an image-based modeling and rendering system, which we call pop-up light field, that models a sparse light field using a set of coherent layers. In our system, the user specifies how many coherent layers...

A final reconstruction approach for a unified global illumination algorithm
Xavier Granier, George Drettakis
Pages: 163-189
DOI: 10.1145/990002.990006
In the past twenty years, many algorithms have been proposed to compute global illumination in synthetic scenes. Typically, such approaches can deal with specific lighting configurations, but often have difficulties with others. In this article, we...

Removing excess topology from isosurfaces
Zoë Wood, Hugues Hoppe, Mathieu Desbrun, Peter Schröder
Pages: 190-208
DOI: 10.1145/990002.990007
Many high-resolution surfaces are created through isosurface extraction from volumetric representations, obtained by 3D photography, CT, or MRI. Noise inherent in the acquisition process can lead to geometrical and topological errors. Reducing...
