The application of volume-rendering techniques to the display of surfaces from sampled
scalar functions of three spatial dimensions is discussed. It is not necessary to fit geometric …

ABSTRACT A fast and simple voxel traversal algorithm through a 3D space partition is
introduced. Going from one voxel to its neighbour requires only two floating point …

Volume rendering is a technique for visualizing sampled scalar or vector fields of three
spatial dimensions without fitting geometric primitives to the data. A subset of these …

We present a solution to the aliasing problem for shadow algorithms that use depth maps.
The solution is based on a new filtering technique called percentage closer filtering. In …

This book provides a fundamental understanding of global illumination algorithms. It
discusses a broad class of algorithms for realistic image synthesis and introduces a …

Global illumination research aiming at the photo-realistic image synthesis pushes forward
research in computer graphics as a whole. The computation of visually plausible images is …

The various types of shadows are characterized. Most existing shadow algorithms are
described, and their complexities, advantages, and shortcomings are discussed. Hard …

The application of several ray-tracing techniques, in combination with GTD/UTD
(geometrical theory of diffraction/uniform theory of diffraction), for an efficient analysis of …

This paper describes a bidirectional Monte Carlo ray tracing method simulating global
illumination in models containing complex objects that do not have to be tessellated. The …

Shadow maps provide a fast and convenient method of identifying shadows in scenes but
can introduce aliasing. This paper introduces the Adaptive Shadow Map (ASM) as a solution …
