Animation of Bubbles in Liquid
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present a new fluid animation technique in which liquid and gas interact with each other, using the exampleof bubbles rising in water. In contrast to previous studies which only focused on one fluid, our system considersboth ...
Freeform Shape Representations for Efficient Geometry Processing
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
The most important concepts for the handling and storage of freeform shapes in geometry processing applications are parametric representations and volumetric representations. Both have their specific advantages and drawbacks. ...
ShieldTester: Cell-to-Cell Visibility Test for Surface Occluders
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present a novel Cell-To-Cell Visibility (C2CV) algorithm, which given two polyhedra, AandBand a connectedand oriented manifold triangle mesh, S offers a simple, fast and conservative test for detecting when A and B ...
Sub-Voxel Topology Control for Level-Set Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Active contour models are an efficient, accurate, and robust tool for the segmentation of 2D and 3D image data.In particular, geometric deformable models (GDM) that represent an active contour as the level set of an ...
Field Functions for Blending Range Controls on Soft Objects
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
This paper proposes new field functions that have adjustable inner radius and outer radius of influence. Incorporatingthe proposed field functions with soft object modeling, soft blending, Ricci's super-ellipsoid blends, ...
Planning Collision-Free Reaching Motions for Interactive Object Manipulation and Grasping
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We present new techniques that use motion planning algorithms based on probabilistic roadmaps to control 22 degrees of freedom (DOFs) of human-like characters in interactive applications. Our main purpose is the automatic ...
BDAM - Batched Dynamic Adaptive Meshes for High Performance Terrain Visualization
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
This paper describes an efficient technique for out-of-core rendering and management of large textured terrainsurfaces. The technique, called Batched Dynamic Adaptive Meshes (BDAM), is based on a paired tree structure:a ...
Planned Sampling of Spatially Varying BRDFs
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Measuring reflection properties of a 3D object involves capturing images for numerous viewing and lightingdirections. We present a method to select advantageous measurement directions based on analyzing the estimationof ...
Interactive Rendering with Bidirectional Texture Functions
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
We propose a new technique for efficiently rendering bidirectional texture functions (BTFs). A 6D BTF describesthe appearance of a material as a texture that depends on the lighting and viewing directions. As such, a ...
Animating Hair with Loosely Connected Particles
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
This paper presents a practical approach to the animation of hair at an interactive frame rate. In our approach,we model the hair as a set of particles that serve as sampling points for the volume of the hair, which covers ...
