Screen Space Obscurances
(The Eurographics Association, 2009)
La simulación de la iluminación indirecta en una escena suele ser muy costosa por lo que normalmente ésta se usa de forma precalculada para escenas estáticas. En este artículo proponemos un algoritmo que aproxima el cálculo ...
Grafito Virtual
(The Eurographics Association, 2009)
Abstract Los trabajos recientes en la visualización expresiva han producido resultados comparables a las imágenes artísticas. Recientemente el campo de la realidad virtual ha desarrollado herramientas que permiten al artista ...
Técnicas Multirresolución para Visualización de Información Vectorial 3D en SIG
(The Eurographics Association, 2009)
Abstract La representación de datos vectoriales (carreteras, lagos, ciudades, etc) es una parte fundamental en los sistemas de información geográfica, tanto para visualizar la información como para procesos de análisis. ...
A Framework for Physically Based Forest Fire Animation
(The Eurographics Association, 2009)
Abstract In this paper, we propose a conceptual framework for animating physically based forest fires. Animating forest fire is a computationally demanding task as trees are intricate structures and fire is a highly complex ...
Facial Expression Transferring with a Deformable Model
(The Eurographics Association, 2009)
This paper presents an automated approach to transferring facial expressions from a generic facial model onto various individual facial models without requiring any prior correspondences and manual interventions during the ...
Fast and Accurate Finite Element Method for Deformation Animations
(The Eurographics Association, 2009)
We present a matrix clustering method for speeding up finite element computations for non-rigid object animation. The method increases the efficiency of computing deformation dynamics through a compression scheme that ...
Hardware Accelerated Shaders Using FPGAs
(The Eurographics Association, 2009)
We demonstrate that Field Programable Gate Arrays (FPGAs) can be used to accelerate shading of surfaces for production quality rendering (a task standard interactive graphics hardware is generally ill-suited to) by allowing ...
An Aliasing Theory of Shadow Mapping
(The Eurographics Association, 2009)
Shadow mapping is a popular image-based technique for real-time shadow rendering. Although numerous improvements have been made to help anti-aliasing in shadow mapping, there is a lack of mathematical tools that allow us ...
Design and Evaluation of a Hardware Accelerated Ray Tracing Data Structure
(The Eurographics Association, 2009)
The increase in graphics card performance and processor core count has allowed significant performance accel- eration for ray tracing applications. Future graphics architectures are expected to continue increasing the ...
Visual Representation of Multiple Associations in Data using Constrained Graph Layout
(The Eurographics Association, 2009)
This paper presents a new approach for simultaneously visualizing multiple exclusive associations, defined on the same dataset, using constrained graph layout. We work with two different associations at a time, which can ...
