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 ... -
Beyond Stippling - Methods for Distributing Objects on the Plane
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Conventionally, stippling is an effective technique for representing surfaces in pen-and-ink. We present new efficientmethods for stipple drawings by computer. In contrast to already existing techniques, arbitrary shapes ... -
Progressive Simplification of Tetrahedral Meshes Preserving All Isosurface Topologies
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In this paper, we propose a novel technique for constructing multiple levels of a tetrahedral volume dataset whilepreserving the topologies of all isosurfaces embedded in the data. Our simplification technique has two ... -
Multiresolution Surface Representation Based on Displacement Volumes
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We propose a new representation for multiresolution models which uses volume elements enclosed between thedifferent resolution levels to encode the detail information. Keeping these displacement volumes locally constantduring ... -
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 ... -

Solving Geometric Optimization Problems using Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We show how to use graphics hardware for tackling optimization problems arising in the field of computationalgeometry. We exemplarily discuss three problems, where combinatorial algorithms are inefficient or hard to ... -
Automatic texture atlas generation from trimmed NURBS models
(Blackwell Publishers, Inc and the Eurographics Association, 2003)A Texture Atlas is a two dimensional representation of a 3D model usable for paint systems or as a sewing pattern.The field of texture atlas generation from polygonal models has been well exploited in the recent years. The ... -
Shadow Volumes on Programmable Graphics Hardware
(Blackwell Publishers, Inc and the Eurographics Association, 2003)One of the best choices for fast, high quality shadows is the shadow volume algorithm. However, for real timeapplications the extraction of silhouette edges can significantly burden the CPU, especially with highly ... -
Image Categorization using Color Blobs in a Mobile Environment
(Blackwell Publishers, Inc and the Eurographics Association, 2003)This paper generalizes the basic idea of blobs in preattentive perception using color information. This is usedas the base of a basic classification of low resolution pictures taken with mobile phones. This classification, ... -
Adaptive Logarithmic Mapping For Displaying High Contrast Scenes
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We propose a fast, high quality tone mapping technique to display high contrast images on devices with limited dynamicrange of luminance values. The method is based on logarithmic compression of luminance values, imitatingthe ... -
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 ... -
Out-of-core compression and decompression of large n-dimensional scalar fields
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present a simple method for compressing very large and regularly sampled scalar fields. Our method is particularlyattractive when the entire data set does not fit in memory and when the sampling rate is high relative ... -
Hierarchical and Heterogenous Reactive Agents for Real-Time Applications
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present a generic concept for autonomous agents with reactive behavior based on situation recognition in real-time environments. Our approach facilitates behavior development through specialization of existing behavior ... -
Realistic Animation of Fluid with Splash and Foam
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In this paper we describe a method for modeling and rendering dynamic behavior of fluids withsplashes and foam. A particle system is built into a fluid simulation system to represent an ocean wavecresting and spraying over ... -
Precise Ink Drawing of 3D Models
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Drawings made with precise pen strokes accurately reveal the geometric forms that give subjects their characteristicshape. We present a system for non-photorealistic rendering of precise drawing strokes over dense 3Dtriangle ... -
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 ... -
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 ... -
Rendering and Affect
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Previous studies at the intersection between rendering and psychology have concentrated on issues such as realismand acuity. Although such results have been useful in informing development of realistic rendering ...
