Shape distributions
Robert Osada, Thomas Funkhouser, Bernard Chazelle, David Dobkin
Pages: 807-832
DOI: 10.1145/571647.571648
Measuring the similarity between 3D shapes is a fundamental problem, with applications in computer graphics, computer vision, molecular biology, and a variety of other fields. A challenging aspect of this problem is to find a suitable shape signature...

Ordered and quantum treemaps: Making effective use of 2D space to display hierarchies
Benjamin B. Bederson, Ben Shneiderman, Martin Wattenberg
Pages: 833-854
DOI: 10.1145/571647.571649
Treemaps, a space-filling method for visualizing large hierarchical data sets, are receiving increasing attention. Several algorithms have been previously proposed to create more useful displays by controlling the aspect ratios of the rectangles that...

Modelling with implicit surfaces that interpolate
Greg Turk, James F. O'Brien
Pages: 855-873
DOI: 10.1145/571647.571650
We introduce new techniques for modelling with interpolating implicit surfaces. This form of implicit surface was first used for problems of surface reconstruction and shape transformation, but the emphasis of our work is on model creation....

Smoothing an overlay grid to minimize linear distortion in texture mapping
Alla Sheffer, Eric de Sturler
Pages: 874-890
DOI: 10.1145/571647.571651
Texture is an essential component of computer generated models. For a texture mapping procedure to be effective it has to generate continuous textures and cause only small mapping distortion. The Angle Based Flattening (ABF) parameterization...
