HIRASP: A Hierarchical Interactive Rastergraphics System Based on Pattern Graphs and Pattern Expressions
(Eurographics Association, 1987)
To exploit the full capabilities of raster graphics, two and three dimensional drawing primitives should play a preponderant role in the specification of a graphics standard. In addition there should be facilities for ...
An Intersection-Sensitive Hidden-Surface Algorithm
(Eurographics Association, 1987)
Given a set of pairwise disjoint planar polygonal faces with altogether N edges in the three-dimensional space. Let k be the number of intersection points of the projections of the edges in a projection plane, 0 < k < ...
A Model for Description and Synthesis of Heterogeneous Textures
(Eurographics Association, 1989)
Existing texture models either describe textures as a non-hierarchical surface property (by means of Markov chains, time series and other stochastic methods) or distinguish only between micro and macro textures. Besides ...
DisArray: A 16x16 RasterOp Processor
(The Eurographics Association, 1983)
RasterOp is a powerful primitive operation for raster graphics. To improve the execution rate of this operation, a machine with a set of 256 1-bit processors organised as a 16x16 array has been constructed. This machine ...
A Method for Providing Full Interactive Control of the Shape of 3-D Curves and Surfaces
(Eurographics Association, 1988)
This paper presents a new method for providing an interactive local control on 3-D curves and surfaces. The possibility of interacting directly on the vector tangent to the curve at each control point (e.g. changing its ...
