• Virtual Garments: A Fully Geometric Approach for Clothing Design 

  Decaudin, Philippe; Julius, Dan; Wither, Jamie; Boissieux, Laurence; Sheffer, Alla; Cani, Marie-Paule (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 

  Ijiri, T.; Owada, S.; Igarashi, T. (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 

  Weinkauf, T.; Theisel, H.; Hege, H.-C.; Seidel, H.-P. (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 

  Rezk-Salama, Christof; Kolb, Andreas (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 

  Grundland, Mark; Vohra, Rahul; Williams, Gareth P.; Dodgson, Neil A. (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 

  Jang, Yun; Botchen, Ralf P.; Lauser, Andreas; Ebert, David S.; Gaither, Kelly P.; Ertl, Thomas (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 

  Willis, Philip (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 

  Guan, Yu; Chen, Wei; Liang, Xiao; Ding, Ziang; Peng, Qunsheng (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 

  Grinspun, Eitan; Gingold, Yotam; Reisman, Jason; Zorin, Denis (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 

  Marinov, Martin; Kobbelt, Leif (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 

  Schreiner, John; Scheidegger, Carlos E.; Fleishman, Shachar; Silva, Claudio T. (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 

  Guenther, Johannes; Friedrich, Heiko; Wald, Ingo; Seidel, Hans-Peter; Slusallek, Philipp (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 ...

• Sweep-based Freeform Deformations 

  Yoon, Seung-Hyun; Kim, Myung-Soo (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 

  Baxter, William; Anjyo, Ken-ichi (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, ...
