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 ... -
Adaptive Ray Tracing of Subdivision Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Subdivision Surfaces as well as (interactive) ray tracing have become an important issue in computer graphics.But ray tracing of subdivision surfaces has received only little attention. We present a new approach for ... -
Advanced Design for a Realistic Virtual Brush
(Blackwell Publishers, Inc and the Eurographics Association, 2003)This paper proposes a novel algorithmic framework for an advanced virtual brush to be used in interactive digitalpainting. The framework comprises the following components: a geometry model of the brush using 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 ... -
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 ... -
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 ... -
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 ... -
Cloth Motion Capture
(Blackwell Publishers, Inc and the Eurographics Association, 2003)Recent years have seen an increased interest in motion capture systems. Current systems, however, are limitedto only a few degrees of freedom, so that effectively only the motion of linked rigid bodies can be acquired. ... -
Compression of 2D Vector Fields Under Guaranteed Topology Preservation
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In this paper we introduce a new compression technique for 2D vector fields which preserves the complete topology, i.e., the critical points and the connectivity of the separatrices. As the theoretical foundation of the ... -
Fast Photo-Realistic Rendering of Trees in Daylight
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We propose a fast approach for photo-realistic rendering of trees under various kinds of daylight, which is particularlyuseful for the environmental assessment of landscapes. In our approach the 3D tree models are transformedto ... -
A Fast Rendering Method for Refractive and Reflective Caustics Due to Water Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2003)In order to synthesize realistic images of scenes that include water surfaces, the rendering of optical effectscaused by waves on the water surface, such as caustics and reflection, is necessary. However, rendering causticsis ... -
A Few Good Lines: Suggestive Drawing of 3D Models
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present a method for rendering 3D models in the traditionalline-drawing style used in artistic and scientificillustrations. The goal is to suggest the 3D shape of the objectsusing a small number of lines drawn with ... -
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, ... -
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. ... -
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 ... -
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 ... -
Hierarchical Higher Order Face Cluster Radiosity for Global Illumination Walkthroughs of Complex Non-Diffuse Environments
(Blackwell Publishers, Inc and the Eurographics Association, 2003)We present an algorithm for simulating global illumination in scenes composed of highly tessellated objects withdiffuse or moderately glossy reflectance. The solution method is a higher order extension of the face cluster ... -
