Intelligent Interactive Volume Classification
(The Eurographics Association, 2013)
This paper defines an intelligent and interactive framework to classify multiple regions of interest from the original data on demand, without requiring any preprocessing or previous segmentation. The proposed intelligent ...
Bezier Crust on Quad Subdivision Surface
(The Eurographics Association, 2013)
Subdivision surfaces have been widely used in computer graphics and can be classified into two categories, approximating and interpolatory. Representative approximating schemes are Catmull-Clark (quad) and Loop (triangular). ...
Non-rigid 3D Shape Retrieval via Sparse Representation
(The Eurographics Association, 2013)
Shape descriptor design is an important but challenging problem for non-rigid 3D shape retrieval. Recently, bagof- words based methods are widely used to integrate a model's local shape descriptors into a global histogram. ...
Fast Random Sampling of Triangular Meshes
(The Eurographics Association, 2013)
We present a simple and fast algorithm for generating randomly distributed points on a triangle mesh with probability density specified by a two-dimensional texture. Efficiency is achieved by resampling the density texture ...
An Improved Friction Model for Cloth Simulation
(The Eurographics Association, 2013)
Friction is a complex phenomenon that resists tangential motion between two contacting objects. In computer graphics, existing cloth simulation methods have typically used a Coulomb model for friction, both static and ...
A Thin Shell Approach to the Registration of Implicit Surfaces
(The Eurographics Association, 2013)
Frequently, one aims at the co-registration of geometries described implicitly by images as level sets. This paper proposes a novel shape sensitive approach for the matching of such implicit surfaces. Motivated by physical ...
A Tracking Approach for the Skeletonization of Tubular Parts of 3D Shapes
(The Eurographics Association, 2013)
In this paper we propose a new simple and efficient method to characterize shapes by segmenting their elongated parts and characterizing them with their centerlines. We call it Tubular Section Tracking, because it consists ...
Level of Detail for Real-Time Volumetric Terrain Rendering
(The Eurographics Association, 2013)
Terrain rendering is an important component of many GIS applications and simulators. Most methods rely on heightmap-based terrain which is simple to acquire and handle, but has limited capabilities for modeling features ...
Tridiagonal Matrix Formulation for Inextensible Hair Strand Simulation
(The Eurographics Association, 2013)
This paper proposes a method to simulate inextensible hair strands using tridiagonal matrix formulation in which distance constraints are formulated as a linear system. The proposed method avoids constructing a full matrix ...
Initial Steps for the Coupling of JavaScript Physics Engines with X3DOM
(The Eurographics Association, 2013)
During the past years, first physics engines based on JavaScript have been developed for web applications. These are capable of displaying virtual scenes much more realistically. Thus, new application areas can be opened ...
