Conditions for tangent plane continuity over recursively generated B-spline surfaces
A. A. Ball, D. J. T. Storry
Pages: 83-102
DOI: 10.1145/42458.42459
The continuity properties of recursively generated B-spline surfaces over an arbitrary topology have been related to the eigenproperties of the local subdivision transformation. In this paper a discrete Fourier transform technique is employed to...

On the power of the frame buffer
Donald Fussell, Alain Fournier
Pages: 103-128
DOI: 10.1145/42458.42460
Raster graphics displays are almost always refreshed out of a frame buffer in which a digital representation of the currently visible image is kept. The availability of the frame buffer as a two-dimensional memory array representing the...

A decomposable algorithm for contour surface display generation
Michael J. Zyda
Pages: 129-148
DOI: 10.1145/42458.42461
We present a study of a highly decomposable algorithm useful for the parallel generation of a contour surface display. The core component of this algorithm is a two-dimensional contouring algorithm that operates on a single 2 x 2 subgrid of a...
