Task-analytic approach to the automated design of graphic presentations
Stephen M. Casner
Pages: 111-151
DOI: 10.1145/108360.108361
BOZ is an automated graphic design and presentation tool that designs graphics based on an analysis of the task for which a graphic is intended to support. When designing a graphic, BOZ aims to optimize two ways in which graphics help expedite...

Integer forward differencing of cubic polynomials: analysis and algorithms
R. Victor Klassen
Pages: 152-181
DOI: 10.1145/108360.108364
Two incremental cubic interpolation algorithms are derived and analysed. Each is based on a known linear interpolation algorithm and modified for third order forward differencing. The tradeoff between overflow avoidance and loss of precision has...

A triangulation algorithm from arbitrary shaped multiple planar contours
A. B. Ekoule, F. C. Peyrin, C. L. Odet
Pages: 182-199
DOI: 10.1145/108360.108363
Conventional triangulation algorithms from planar contours suffer from some limitations. For instance, incorrect results can be obtained when the contours are not convex, or when the contours in two successive slices are very different. In the...

Interactive measurement of three-dimensional objects using a depth buffer and linear probe
Shawn C. Becker, William A. Barrett, Don R. Olsen
Pages: 200-207
DOI: 10.1145/108360.108446
