A simple method for improved color printing of monitor images
Michael G. Lamming, Warren L. Rhodes
Pages: 345-375
DOI: 10.1145/88560.88567
To print image data optimized for display on a color monitor, the red, green, and blue values that drive the display must be transformed into data that control the amounts of cyan, magenta, yellow, and black on the print. The differences in the...

Fast line scan-conversion
J. G. Rokne, Brian Wyvill, Xiaolin Wu
Pages: 376-388
DOI: 10.1145/88560.88572
A major bottleneck in many graphics displays is the time required to scan-convert straight line segments. Most manufacturers use hardware based on Bresenham's [5] line algorithm. In this paper an algorithm is developed based on the original...

Contour tracing by piecewise linear approximations
David P. Dobkin, Allan R. Wilks, Silvio V. F. Levy, William P. Thurston
Pages: 389-423
DOI: 10.1145/88560.88575
We present a method for tracing a curve that is represented as the contour of a function in Euclidean space of any dimension. The method proceeds locally by following the intersections of the contour with the facets of a triangulation of space....

An investigation of curvature variations over recursively generated B-spline surfaces
A. A. Ball, D. J. T. Storry
Pages: 424-437
DOI: 10.1145/88560.88580
The continuity properties of recursively generated B-spline surfaces over an arbitrary topology have been related to the eigenproperties of the local subdivision tranformation, and conditions have been established on the subdivision weightings...
