Strands, Gravity and Botanical Tree Imagery
(Blackwell Science Ltd and the Eurographics Association, 1994)This paper presents a technique for the modelling and rendering of realistic botanical tree images. A strand model is used that is analogous to the internal vascular structure of a tree. The model is"grown" under the ... -
Computer Generated Copper Plates
(Blackwell Science Ltd and the Eurographics Association, 1994)Making computer generated copper plates with image generation algorithms is presented. The method uses a kind of volume texturing in connection with image processing algorithms, and is suitable for implementation in a ray ... -
Experiments in the Parallel Computation of 3D Convex Hulls
(Blackwell Science Ltd and the Eurographics Association, 1994)Two parallel implementations of a 3D convex hull algorithm are reported. The paper considers a MIMD distributed memory architecture and the implementations are carried out on the Meiko Computing Surface using T800 transputers ... -
Classification of Ray-Generators in Uniform Subdivisions and Octrees for Ray Tracing
(Blackwell Science Ltd and the Eurographics Association, 1994)Spatial subdivisions cause an enormous acceleration of ray tracing due to the reduction of ray-object intersections. For this purpose it is necessary to generate the sequence of ray-cells (all cells met consecutively by a ... -
A Data Structure for Artificial Terrain Generation
(Blackwell Science Ltd and the Eurographics Association, 1994)This paper addresses the problems of maintaining the consistency of spatial data under recursive subdivision algorithms for artificial terrain generation. Fractal modelling techniques are outlined, with particular reference ... -
Controllable Locality in C2 Interpolating Curves by B2-splines / S-splines
(Blackwell Science Ltd and the Eurographics Association, 1994)This paper presents a systematic scheme for controlling the local behaviour of C2 interpolating curves, based on the cubic B2-splines and the quartic S-splines. Both splines have an additional control point obtained by ...
