Wrinkling Coarse Meshes on the GPU
(The Eurographics Association and Blackwell Publishing, Inc, 2006)The simulation of complex layers of folds of cloth can be handled through algorithms which take the physical dynamics into account. In many cases, however, it is sufficient to generate wrinkles on a piece of garment which ... -
Real-Time Weighted Pose-Space Deformation on the GPU
(The Eurographics Association and Blackwell Publishing, Inc, 2006)WPSD (Weighted Pose Space Deformation) is an example based skinning method for articulated body animation. The per-vertex computation required in WPSD can be parallelized in a SIMD (Single Instruction Multiple Data) manner ... -
Semantic Photo Synthesis
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Composite images are synthesized from existing photographs by artists who make concept art, e.g., storyboards for movies or architectural planning. Current techniques allow an artist to fabricate such an image by digitally ... -
Sweep-based Freeform Deformations
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose a sweep-based approach to the freeform deformation of three-dimensional objects. Instead of using a volume enclosing the whole object, we approximate only its deformable parts using sweep surfaces. The vertices ... -
Cross Dissolve Without Cross Fade: Preserving Contrast, Color and Salience in Image Compositing
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Linear interpolation is the standard image blending method used in image compositing. By averaging in the dynamic range, it reduces contrast and visibly degrades the quality of composite imagery. We demonstrate how to ... -
Cache-Efficient Layouts of Bounding Volume Hierarchies
(The Eurographics Association and Blackwell Publishing, Inc, 2006) -
GPU-based Collision Detection for Deformable Parameterized Surfaces
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Based on the potential of current programmable GPUs, recently several approaches were developed that use the GPU to calculate deformations of surfaces like the folding of cloth or to convert higher level geometry to ... -
Direct (Re)Meshing for Efficient Surface Processing
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose a novel surface remeshing algorithm. While many remeshing algorithms are based on global parametrization or local mesh optimization, our algorithm is closely related to surface reconstruction techniques and it ... -
A Robust Two-Step Procedure for Quad-Dominant Remeshing
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose a new technique for quad-dominant remeshing which separates the local regularity requirements from the global alignment requirements by working in two steps. In the first step, we apply a slight variant of ... -
Projective Alpha Colour
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Alpha colours were introduced for image compositing, using a pixel coverage model. Algebraically they resemble homogeneous coordinates, widely used in projective geometry calculations. We show why this is the case. This ... -
Ray Tracing Animated Scenes using Motion Decomposition
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Though ray tracing has recently become interactive, its high precomputation time for building spatial indices usually limits its applications to walkthroughs of static scenes. This is a major limitation, as most applications ... -
Volume-Surface Trees
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Many algorithms in computer graphics improve their efficiency by using Hierarchical Space Subdivision Schemes (HS3), such as octrees, kD-trees or BSP trees. Such HS3 usually provide an axis-aligned subdivision of the 3D ... -
Easy Matting - A Stroke Based Approach for Continuous Image Matting
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose an iterative energy minimization framework for interactive image matting. Our approach is easy in the sense that it is fast and requires only few user-specified strokes for marking the foreground and background. ... -
Virtual Garments: A Fully Geometric Approach for Clothing Design
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Modeling dressed characters is known as a very tedious process. It usually requires specifying 2D fabric patterns, positioning and assembling the min 3D, and then performing a physically-based simulation. The latter accounts ... -

Topological Structures in Two-Parameter-Dependent 2D Vector Fields
(The Eurographics Association and Blackwell Publishing, Inc, 2006)In this paper we extract and visualize the topological skeleton of two-parameter-dependent vector fields. This kind of vector data depends on two parameter dimensions, for instance physical time and a scale parameter. We ... -
Stroke Pattern Analysis and Synthesis
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present a synthesis technique that can automatically generate stroke patterns based on a user-specified reference pattern. Our method is an extension of texture synthesis techniques to vector-based patterns. Such an ... -
Efficient Large Scale Acquisition of Building Interiors
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We describe a system for the rapid acquisition of building interiors. In 40 hours, a two member team with a single acquisition device captured a model of the corridors and 20 individual rooms spanning 6 floors of a large ... -
Seamless Integration of Initial Sketching and Subsequent Detail Editing in Flower Modeling
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present an interactive modeling system for flower composition that supports seamless transformation from an initial sketch to a detailed three-dimensional (3D) model. To begin, the user quickly sketches the overall ... -
Creating Face Models from Vague Mental Images
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We present a novel approach to create plausible 3D face models from vague recollections or incomplete descriptions. This task plays an important role in police work, where composite facial images of suspects need to be ...
