Particle-Based Simulation of Fluids
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Due to our familiarity with how fluids move and interact, as well as their complexity, plausible animation of fluidsremains a challenging problem. We present a particle interaction method for simulating fluids. The ...
Volumetric cell-and-portal generation
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present an algorithm to generate a cell-and-portal decomposition of general indoor scenes. The method is an adaptation of the 3D watershed transform, computed on a distance-to-geometry sampled field. The watershed is ...
Cloth Motion Capture
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Recent years have seen an increased interest in motion capture systems. Current systems, however, are limitedto only a few degrees of freedom, so that effectively only the motion of linked rigid bodies can be acquired. ...
Compression of 2D Vector Fields Under Guaranteed Topology Preservation
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
In this paper we introduce a new compression technique for 2D vector fields which preserves the complete topology, i.e., the critical points and the connectivity of the separatrices. As the theoretical foundation of the ...
Hierarchical Context-based Pixel Ordering
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present a context-based scanning algorithm which reorders the input image using a hierarchical representationof the image. Our algorithm optimally orders (permutes) the leaves corresponding to the pixels, by minimizing ...
Fast Photo-Realistic Rendering of Trees in Daylight
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We propose a fast approach for photo-realistic rendering of trees under various kinds of daylight, which is particularlyuseful for the environmental assessment of landscapes. In our approach the 3D tree models are transformedto ...
Multi-scale Feature Extraction on Point-Sampled Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present a new technique for extracting line-type features on point-sampled geometry. Given an unstructuredpoint cloud as input, our method first applies principal component analysis on local neighborhoods toclassify ...
Creation and Control of Real-time Continuous Level of Detail on Programmable Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Continuity in level of detail sequences is essential in hiding visual artefacts that occur when switching between discrete levels of detail. However, construction and implementation of these sequences is prohibitively ...
Two-dimensional Potential Fields for Advanced Implicit Modeling Operators
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Current methods for building models using implicit volume techniques present problems defining accurate and controllable blend shapes between implicit primitives. We present new methods to extend the freedom and controllability ...
Automatic Hybrid Hierarchy Creation: a Cost-model Based Approach
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
While using hierarchical search structures has been proved as one of the most efficient acceleration techniques when rendering complex scenes, automatic creation of appropriate hierarchies is not solved yet. Well-known ...
