Particle Oriented Collision Detection using Simplicial Coverings and Tetra-Trees
(The Eurographics Association and Blackwell Publishing Ltd., 2006)Collision detection (CD) among complex objects in motion is an open question because of its algorithmic complexity. In this paper, we present a CD algorithm between a particle and a complex rigid solid. In order to represent ... -
A PBL Experience in the Teaching of Computer Graphics
(The Eurographics Association and Blackwell Publishing Ltd., 2006)Project-Based Learning (PBL) is an educational strategy to improve student s learning capability that, in recent years, has had a progressive acceptance in undergraduate studies. This methodology is based on solving a ... -
Principles and Applications of Computer Graphics in Medicine
(The Eurographics Association and Blackwell Publishing Ltd., 2006)The medical domain provides excellent opportunities for the application of computer graphics, visualization and virtual environments, with the potential to help improve healthcare and bring benefits to patients. This survey ... -
Rendering Soft Shadows using Multilayered Shadow Fins
(The Eurographics Association and Blackwell Publishing Ltd., 2006)Generating soft shadows in real time is difficult. Exact methods (such as ray tracing, and multiple light source simulation) are too slow, while approximate methods often overestimate the umbra regions. In this paper, we ... -
Speed-up Technique for a Local Automatic Colour Equalization Model
(The Eurographics Association and Blackwell Publishing Ltd., 2006)In this paper we propose a speed-up technique for a local automatic colour equalization operator derived from a model of the human vision system. This method is characterized by local and global filtering effects, that ... -

Virtual Reality Course-A Natural Enrichment of Computer Graphics Classes
(The Eurographics Association and Blackwell Publishing Ltd., 2006)This paper shows how the Virtual Reality (VR) course can naturally extend and practice a wide range of Computer Graphics (CG) principles and programming techniques. Thanks to real-time processing requirements, attention ... -
A Weighted Error Metric and Optimization Method for Antialiasing Patterns
(The Eurographics Association and Blackwell Publishing Ltd., 2006)Displaying a synthetic image on a computer display requires determining the colors of individual pixels. To avoid aliasing, multiple samples of the image can be taken per pixel, after which the color of a pixel may be ...
