SIAS, Strokes Interpreted Animated Sequences
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
The goals of the bulk of commercial computer systems for graphics and animated film/video are different from the kind of systems involving the production of art. The former systems are developed for industrial application. ...
Hidden Octree Node Removal as a Pipeline Process
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
A processing pipeline solution to the generation and display of octree encoded 3-D objects is described. Particular emphasis is given to an algorithm which removes that part a of linear octree code which describes parts ...
Notes on the Mathematics of the PHIGS Viewing Pipeline
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
It is well known that homogeneous linear matrix transformations of the projective space may be efficiently used for the representation and the execution of common geometrical transformations but the general class of such ...
Polygon Triangulation Algorithm as a Powerful Core Processor of PLAN-I
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
A concise, complete and reliable algorithm for triangulating an arbitrary polygon is presented as a powerful core processor of PLAN-I (Production Layout Automation Nucleus) system1. A polygon with inner loops is converted ...
Towards an Object-Oriented Interaction Model for Graphics User Interfaces
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
The increasing importance of the User Interface Management System THESEUS stimulated the development of a formalized graphics input model that is based on the THESEUS input concepts. This paper presents cooperative work ...
Yet another Remark on the Modelling Clip Problem
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
Algorithm for Clpping Arbitrary Polygons
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
A Parallel HW/SW Environment for Image Synthesis
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
AbstractIn designing graphical workstations for high-level performance presentations of graphical models, the main goal nowadays is to perform some effective real-time traversal and rendering of data. In this paper we ...
Photosimulation: Interreflection with Arbitrary Reflectance Models and Illumination
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
Methods for realistic image synthesis are described. Exact mathematical establishment of reflectance models is presented, together with the development of feasible reflectance models meeting the energy balance. A new ...
On Implementing Parallel GKS
(Blackwell Publishing Ltd and the Eurographics Association, 1989)
This report investigates the problems involved in implementing the GKS 2D graphics standard in Occam. Whilst some of the detail is language specific, similar problems arise with implementations in any parallel system and ...
