Control Points for Multivariate B-Spline Surfaces over Arbitrary Triangulations
(Blackwell Science Ltd and the Eurographics Association, 1991)
This paper describes first results of a test implementation that implements the new multivariate B-splines as recently developed by Dahmen et al. 10for quadratics and cubics. The surface scheme is based on blending functions ...
Object-Oriented Data Modelling for Graphics Databases: a Declarative Approach
(Blackwell Science Ltd and the Eurographics Association, 1991)
This paper presents a new scheme to integrate the declarative approach to graphics and object-oriented data modelling techniques to form a fruitful symbiosis for constraint-based graphics database systems. It has rich ...
Development of an Intelligent Wheelchair Using Computer Graphics Animation and Simulation
(Blackwell Science Ltd and the Eurographics Association, 1991)
A new robot simulator JC-1 is used as a control software development tool in a project in progress where an intelligent wheelchair for a blind user is being developed. The intelligent wheelchair is planned to be able to ...
The Shortest Way to Draw a Connected Picture
(Blackwell Science Ltd and the Eurographics Association, 1991)
With any word over the alphabet ?=r, r?, u, u, we associate a connected picture in the following manner: the reading of each letter of this word induces a unit line: r (r?, u, u respectively) stands for a right (left, up, ...
Million-Point Sculptures
(Blackwell Science Ltd and the Eurographics Association, 1991)
Visually interesting chaotic attractors resembling sculpture are described.
From Math Comes Beauty: Monkey Curves, Spirals, and Saddles
(Blackwell Science Ltd and the Eurographics Association, 1991)
This informal note presents computational recipes for producing visually interesting surfaces.
