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 ... -
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 ... -
Implicit Surface Modelling with a Globally Regularised Basis of Compact Support
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We consider the problem of constructing a globally smooth analytic function that represents a surface implicitly by way of its zero set, given sample points with surface normal vectors.The contributions of the paper include ... -
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 ... -
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 ... -
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 ... -
Opacity Peeling for Direct Volume Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2006)The most important technique to visualize 3D scalar data, as they arise e.g. in medicine from tomographic measurement, is direct volume rendering. A transfer function maps the scalar values to optical properties which are ... -
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 ... -
Enhancing the Interactive Visualization of Procedurally Encoded Multifield Data with Ellipsoidal Basis Functions
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Functional approximation of scattered data is a popular technique for compactly representing various types of datasets in computer graphics, including surface, volume, and vector datasets. Typically, sums of Gaussians or ... -
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 ... -
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. ... -
Computing discrete shape operators on general meshes
(The Eurographics Association and Blackwell Publishing, Inc, 2006)Discrete curvature and shape operators, which capture complete information about directional curvatures at a point, are essential in a variety of applications: simulation of deformable two-dimensional objects, variational ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Latent Doodle Space
(The Eurographics Association and Blackwell Publishing, Inc, 2006)We propose the concept of a latent doodle space, a low-dimensional space derived from a set of input doodles, or simple line drawings. The latent space provides a foundation for generating new drawings that are similar, ...
