Data-driven Tetrahedral Mesh Subdivision
(The Eurographics Association, 2006)
Given a tetrahedral mesh immersed in a voxel model, we present a method to refine the mesh to reduce the discrepancy between interpolated values based on either scheme at arbitrary locations. An advantage of the method ...
Collision Detection for Deformable Objects using Octrees
(The Eurographics Association, 2006)
We present an algorithm for collision detection between multiple deformable objects translating in a large environment. We use Spatial Partitioning to subdivide the scene and a Bounding Volume Hierarchy to decompose the ...
Distance Based Feature Detection on 3D Point Sets
(The Eurographics Association, 2009)
We propose a distance based algorithm for implicit feature detection on 3D point sets. Instead of directly determining whether a point belongs to a feature of the 3D point set or not, we first compute the distance between ...
Higher Dimensional Vector Field Visualization: A Survey
(The Eurographics Association, 2009)
Vector field visualization research has evolved very rapidly over the last two decades. There is growing consensus amongst the research community that the challenge of two-dimensional vector field visualization is virtually ...
A Benchmarking Framework for Static Collision Detection
(The Eurographics Association, 2008)
Performanceof static collision detection queries depends on the type of the hierarchy chosen as well as the relative positioning of the colliding objects. In order to evaluate the performance of bounding volume hierarchies, ...
Real-Time Modelling of the Action of Wind on Liquid Surfaces
(The Eurographics Association, 2006)
This work in progress aims to model the appearance of the surface of various liquids, when force from a virtual wind is applied. The physical effects caused by a wind force include waves and spray. The appearance of these ...
An Edge-based Approach to Adaptively Refining a Mesh for Cloth Deformation
(The Eurographics Association, 2009)
Simulating cloth in real-time is a challenging endeavour due to the number of triangles necessary to depict the potentially frequent changes in curvature, in combination with the physics calculations which model the ...
Tests de inclusión punto en objeto basados en árboles de intervalos
(The Eurographics Association, 2009)
En este trabajo presentamos varios tests de inclusión punto en objeto, para objetos de dos y tres dimensiones, que utilizan árboles de intervalos como estructura de datos básica. Los tests destacan por su sencillez, escaso ...
Topological Descriptor for CAD Models with Inner Cavities
(The Eurographics Association, 2006)
The current work introduces an algorithm for constructing Reeb graph for CAD models and their inner cavities. The nodes of the graph represent areas of the manifold of the model where topological changes occur. Edges of ...
