Valence-Driven Connectivity Encoding for 3D Meshes
(Blackwell Publishers Ltd and the Eurographics Association, 2001)In this paper, we propose a valence-driven, single-resolution encoding technique for lossless compression of triangle mesh connectivity. Building upon a valence-based approach pioneered by Touma and Gotsman22 , we design ... -
Coarse-to-fine surface simplification with geometric guarantees
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Let PC be a 3D point cloud and ? be a positive value called tolerance. We aim at constructing a triangulated surface S based on a subset PCU of PC such that all the points in PCL=PC?PCU are at distance at most ? from a ... -
Tensor Topology Tracking: A Visualization Method for Time-Dependent 2D Symmetric Tensor Fields
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Topological methods produce simple and meaningful depictions of symmetric, second order two-dimensional tensor fields. Extending previous work dealing with vector fields, we propose here a scheme for the visualization of ... -
A Unified Subdivision Scheme for Polygonal Modeling
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Subdivision rules have traditionally been designed to generate smooth surfaces from polygonal meshes. In this paper we propose to employ subdivision rules as a polygonal modeling tool, specifically to add additional level ... -
Real-Time Volume Deformations
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Real-time free-form deformation tools are primarily based on surface or particle representations to allow for interactive modification and fast rendering of complex models. The efficient handling of volumetric representations, ... -
Fast Visualization of Object Contours by Non-Photorealistic Volume Rendering
(Blackwell Publishers Ltd and the Eurographics Association, 2001)In this paper we present a fast visualization technique for volumetric data, which is based on a recent non-photorealistic rendering technique. Our new approach enables alternative insights into 3D data sets (compared to ... -
Hoops: 3D Curves as Conservative Occluders for Cell-Visibility
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Most visibility culling algorithms require convexity of occluders. Occluder synthesis algorithms attempt to construct large convex occluders inside bulky non-convex sets. Occluder fusion algorithms generate convex occluders ... -
Ray Tracing Triangular Bezier Patches
(Blackwell Publishers Ltd and the Eurographics Association, 2001)We present a new approach to finding ray-patch intersections with triangular Bernstein-Bezier patches of arbitrary degree. This paper extends and complements on the short presentation17 . Unlike a previous approach which ... -
Reflective Interaction in Virtual Environments
(Blackwell Publishers Ltd and the Eurographics Association, 2001)The proliferation of projection-based systems in recent years resulted in a variety of specialised interaction techniques that make Virtual Environments a better man machine interface. However, the success of these techniques ... -
Instant Visibility
(Blackwell Publishers Ltd and the Eurographics Association, 2001)We present an online occlusion culling system which computes visibility in parallel to the rendering pipeline. We show how to use point visibility algorithms to quickly calculate a tight potentially visible set (PVS) which ... -
Resampling Feature and Blend Regions in Polygonal Meshes for Surface Anti-Aliasing
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Efficient surface reconstruction and reverse engineering techniques are usually based on a polygonal mesh representation of the geometry: the resulting models emerge from piecewise linear interpolation of a set of sample ... -
Feature Sensitive Remeshing
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Remeshing artifacts are a fundamental problem when converting a given geometry into a triangle mesh. We propose a new remeshing technique that is sensitive to features. First, the resolution of the mesh is iteratively ... -
Visualization of Isosurfaces with Parametric Cubes
(Blackwell Publishers Ltd and the Eurographics Association, 2001)To render images from volume datasets, an interpolation method also called reconstruction is needed. The level of details of the resultant image closely depends on the filter used for reconstruction. We propose here a new ... -
Detection of Salient Curvature Features on Polygonal Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2001)We develop an approach for stable detection of perceptually salient curvature features on surfaces approximated by dense triangle meshes. The approach explores an "area degenerating" effect of the focal surface near its ... -
Generalized Stochastic Sampling Method for Visualization and Investigation of Implicit Surfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Recently we proposed the stochastic sampling method (SSM), which can numerically generate sample points on complicated implicit surfaces quickly and uniformly. In this paper we generalize the method in two aspects: (1) We ... -
Mesh Optimization for Polygonized Isosurfaces
(Blackwell Publishers Ltd and the Eurographics Association, 2001)In this paper, we propose a method for improvement of isosurface polygonizations. Given an initial polygonization of an isosurface, we introduce a mesh evolution process initialized by the polygonization. The evolving mesh ... -
Adaptive Nonlinear Finite Elements for Deformable Body Simulation Using Dynamic Progressive Meshes
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Realistic behavior of deformable objects is essential for many applications such as simulation for surgical training. Existing techniques of deformable modeling for real time simulation have either used approximate methods ... -
Modeling Dynamic Hair as a Continuum
(Blackwell Publishers Ltd and the Eurographics Association, 2001)In this paper we address the difficult problem of hair dynamics, particularly hair-hair and hair-air interactions. To model these interactions, we propose to consider hair volume as a continuum. Subsequently, we treat the ... -
Modeling Stochastic Dynamical Systems for Interactive Simulation
(Blackwell Publishers Ltd and the Eurographics Association, 2001)We present techniques for constructing approximate stochastic models of complicated dynamical systems for applications in interactive computer graphics. The models are designed to produce realistic interaction at low cost.We ... -
A High Performance Solver for the Animation of Deformable Objects using Advanced Numerical Methods
(Blackwell Publishers Ltd and the Eurographics Association, 2001)Physically based modelling of deformable objects has become the most popular technique to model textiles, skin or human tissue. The crucial problem in the animation of deformable objects is the solution of the resulting ...
