Hierarchical Higher Order Face Cluster Radiosity for Global Illumination Walkthroughs of Complex Non-Diffuse Environments
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present an algorithm for simulating global illumination in scenes composed of highly tessellated objects withdiffuse or moderately glossy reflectance. The solution method is a higher order extension of the face cluster ...
Image Based Interactive Rendering with View Dependent Geometry
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
In this paper we present a novel approach for interactive rendering of virtual views from real image sequences.Combining the concepts of light fields, depth-compensated image warping and view dependent texture mapping,this ...
Interactive Design of Bonsai Tree Models
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Because of their complexity, plant models used in computer graphics are commonly created with proceduralmethods. A difficult problem is the user control of these models: a small number of parameters is insufficient tospecify ...
The Stringed Haptic Workbench: a New Haptic Workbench Solution
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
The workbench is an interesting semi-immersive configuration for interactive tasks. However, haptic feedback, i.e.force and tactile feedback, is one important cue which is missing. To the authors' knowledge, the sole ...
Volumetric Filtering, Modeling and Visualization for Nano-Medicine
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
The 3D structures of individual proteins or small complexes, such as most of the Protein Data Bank entries, are still unable to yield the 'full picture' of a functional biological complex. The study of large macromolecular ...
Solving Geometric Optimization Problems using Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We show how to use graphics hardware for tackling optimization problems arising in the field of computationalgeometry. We exemplarily discuss three problems, where combinatorial algorithms are inefficient or hard to ...
On Visual Similarity Based 3D Model Retrieval
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Automatic texture atlas generation from trimmed NURBS models
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
A Texture Atlas is a two dimensional representation of a 3D model usable for paint systems or as a sewing pattern.The field of texture atlas generation from polygonal models has been well exploited in the recent years. The ...
Shadow Volumes on Programmable Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
One of the best choices for fast, high quality shadows is the shadow volume algorithm. However, for real timeapplications the extraction of silhouette edges can significantly burden the CPU, especially with highly ...
Image Categorization using Color Blobs in a Mobile Environment
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
This paper generalizes the basic idea of blobs in preattentive perception using color information. This is usedas the base of a basic classification of low resolution pictures taken with mobile phones. This classification, ...
