Smooth patching of refined triangulations
Jorg Peters
Pages: 1-9
DOI: 10.1145/383745.383746
This paper presents a simple algorithm for associating a smooth, low-degree polynomial surface with triangulations whose extraordinary mesh nodes are separated by sufficiently many ordinary, 6-valent mesh nodes. Output surfaces are at least...

3D RGB image compression for interactive applications
Insung Ihm, Sanghun Park, Chandrajit Bajaj
Pages: 10-38
DOI: 10.1145/383745.383747
This paper presents a new 3D RGB image compression scheme designed for interactive real-time applications. In designing our compression method, we have compromised between two important goals: high compression ratio and fast random access...

Spatiotemporal sensitivity and visual attention for efficient rendering of dynamic environments
Sumanita Pattanaik, Donald P. Greenberg, Hector Yee
Pages: 39-65
DOI: 10.1145/383745.383748
We present a method to accelerate global illumination computation in prerendered animations by taking advantage of limitations of the human visual system. A spatiotemporal error tolerance map, constructed from psychophysical data based on...
