Photo-Realistic Imaging of Digital Terrains
(Blackwell Science Ltd and the Eurographics Association, 1993)
We present a method for the generation of photo-realistic images of views over terrain datasets by mapping a digital aerial photograph on a perspective projection of a digital elevation map. We use high resolution for both ...
Parallel 3D Delaunay Triangulation
(Blackwell Science Ltd and the Eurographics Association, 1993)
A 4D Ray Tracing
(Blackwell Science Ltd and the Eurographics Association, 1993)
We are going to present a survey of techniques using temporal coherence in between frames to render animation sequences with ray tracing. A new method using temporal coherence in the ray space (lightpath of rays) is proposed. ...
Variational Surface Design and Surface Interrogation
(Blackwell Science Ltd and the Eurographics Association, 1993)
The generation of technical smooth surfaces from a mesh of three-dimensional data points is an important problem in geometric modelling. In this publication we give a survey of some new techniques based on a calculus of ...
Direct 3D Manipulation Techniques for Interactive Constraint-based Solid Modelling
(Blackwell Science Ltd and the Eurographics Association, 1993)
This paper presents a novel constraint-based 3D manipulation approach to interactive constraint-based solid modelling. This approach employs a constraint recognition process to automatically recognise assembly relationships ...
Fast Spheres
(Blackwell Science Ltd and the Eurographics Association, 1993)
A new method for generating sphere-like images, using parabolic surfaces delimited by Bresenham s circle- generation algorithm, is presented. In many cases the resultant images are indistinguishable from spheres illuminated ...
DaScript3D Integrating 3D Graphics in a Page Description Language
(Blackwell Science Ltd and the Eurographics Association, 1993)
Despite the necessity of producing high-quality documents comprising all aspects of electronic publishing, there is still no system available that can generate and integrate two-dimensional (2D) graphics, three-dimensional ...
3D Computational Morphology
(Blackwell Science Ltd and the Eurographics Association, 1993)
Computational Morphology is the analysis of form by computational means. This discipline typically uses techniques from Computational Geometry and Computer Aided Geometric Design. The present paper is more specifically ...
Verve
(Blackwell Science Ltd and the Eurographics Association, 1993)
The design principles of a hardware acceleratorfor volume rendering are described. The architecture represents a voxel subsystem which interfaces easily to any existing workstation. Host requirements are low since it ...
Pseudo-Satellitefilm Using Fractal Clouds to Enhance Animated Weather Forecasting
(Blackwell Science Ltd and the Eurographics Association, 1993)
We have developed a system enabling the National German Meteorological Office to generate pseudo-satellite images and video sequences based on their weather forecasting simulation data. With our system meteorologists can ...
