An approach to 3D pose determination
Norberto Ezquerra, Rakesh Mullick
Pages: 99-120
DOI: 10.1145/234972.234973
The orientation, or pose, of an object is a fundamental property that helps to define the geometrical relationship between the object and its environment. In addition, knowledge of object orientation can also facilitate interpretive and...

Evaluating stereo and motion cues for visualizing information nets in three dimensions
Colin Ware, Glenn Franck
Pages: 121-140
DOI: 10.1145/234972.234975
This article concerns the benefits of presenting abstract data in 3D. Two experiments show that motion cues combined with stereo viewing can substantially increase the size of the graph that can be preceived. The first experiment was designed to...

Time/space tradeoffs for polygon mesh rendering
Reuven Bar-Yehuda, Craig Gotsman
Pages: 141-152
DOI: 10.1145/234972.234976
We investigate architechural schemes, generalizing that of existing graphics engines, supporting fast rendering of traingle meshes. A mesh defined on n vertices is rendered by sending vertices down a graphics pipeline, after...

Comparison of surface and derivative evaluation methods for the rendering of NURB surfaces
William L. Luken, Fuhua Cheng
Pages: 153-178
DOI: 10.1145/234972.234977
Three methods for evaluating the surface coordinates, first derivatives, and normal vectors of a NURB surface are compared. These methods include forward differencing, knot insertion, and a tow-stage Cox-de Boor technique. The computational...
