Function Representation of Solids Reconstructed from Scattered Surface Points and Contours
(Blackwell Science Ltd and the Eurographics Association, 1995)
This paper presents a novel approach to the reconstruction of geometric models and surfaces from given sets of points using volume splines. It results in the representation of a solid by the inequality f(x,y,z) ? 0. The ...
Algorithms for Extracting Correct Critical Points and Constructing Topological Graphs from Discrete Geographical Elevation Data
(Blackwell Science Ltd and the Eurographics Association, 1995)
Researchers in the fields of computer graphics and geographical information systems (GISs) have extensively studied the methods of extracting terrain features such as peaks, pits, passes, ridges, and ravines from discrete ...
