Abstrakt: The dual representation of points, lines and polygons introduced in [Gun88] can also be used for computing convex hulls of a set of points in E2. The main principles of the dual representation and a sketch of the algorithm for convex hull computation are given in this paper. Algorithm can be used both for statical and semi-dynamical case. More details can be seen in [Kol94].1994-01-01T00:00:00ZKolingerová, IvanaRaytracing 3D Linear GraftalsBekaert, PhillipeWillems, Y.

Abstrakt: Many objects in nature, like trees, mountains and seashells, have a property called selfsimilarity. Sometimes this property is very pronounced, other natural phenomena exhibit this property to a lesser degree. During the past years much attention has been paid to fractals, purely selfsimilar objects. We present a formalism, based on the well-known object-instancing graph, to represent objects which are not necessarily purely selfsimilar. We show that Iterated Function Systems and some famous variants can be described elegantly in this formalism. We also present an algorithm to raytrace such objects.1994-01-01T00:00:00ZBekaert, PhillipeWillems, Y.

Abstrakt: This paper describes a mathematical framework for rendering algorithms. Starting from the rendering equation and the potential equation, we will introduce the Global Reflection Distribution Function (GRDF). By using GRDF, we are able to compute the behaviour of light in an environment, independent of the initial lighting or viewpoint conditions. This framework is able to describe most existing rendering algorithms.1994-01-01T00:00:00ZDutré, PhilipLafortune, E.Willems, Y. D.
