  Scopigno, Roberto (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  The recent evolution of graphics technology makes it possible to manage very complex models on inexpensive platforms. These impressive rendering capabilities should be paired with detailed and accurate digital models. The ...

• Interactive Visualization with Programmable Graphics Hardware 

  Ertl, Thomas (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  One of the main scientific goals of visualization is the development of algorithms and appropriate data models which facilitate interactive visual analysis and direct manipulation of the increasingly large data sets which ...

• Artificial Animals and Humans: From Physics to Intelligence 

  Terzopoulos, Demetri (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  The confluence of virtual reality and artificial life, an emerging discipline that spans the computational and biological sciences, has yielded synthetic worlds inhabited by realistic, artificial flora and fauna. Artificial ...

• Modeling Surperspective Projection of Landscapes for Geographical Guide-Map Generation 

  Takahashi, Shigeo; Ohta, Naoya; Nakamura, Hiroko; Takeshima, Yuriko; Fujishiro, Issei (Blackwell Science Ltd and the Eurographics Association, 2002)

  It is still challenging to generate hand-drawn pictures because they differ from ordinary photographs in that they are often drawn as seen from multiple viewpoints. This paper presents a new approach for modeling such ...

• Stylizing Silhouettes at Interactive Rates: From Silhouette Edges to Silhouette Strokes 

  Isenberg, Tobias; Halper, Nick; Strothotte, Thomas (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  A way to create effective stylized line drawings is to draw strokes that start and stop at visible portions along the silhouette of an object to be portrayed. In computer graphics to date, algorithms to extract silhouette ...

• Flattening 3D objects using silhouettes 

  Martin, D.; Fekete, J.D.; Torres, J. C. (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  An important research area in non-photorealistic rendering is the obtention of silhouettes. There are many methods to do this using 3D models and raster structures, but these are limited in their ability to create stylised ...

• Geometric Snakes for Triangular Meshes 

  Lee, Y.; Lee, S. (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  Feature detection is important in various mesh processing techniques, such as mesh editing, mesh morphing, mesh compression, and mesh signal processing. In spite of much research in computer vision, automatic feature ...

• Metamorphosis of Polyhedral Surfaces using Decomposition 

  Shlafman, Shymon; Tal, Ayellet; Katz, Sagi (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  This paper describes an algorithm for morphing polyhedral surfaces based on their decompositions into patches. The given surfaces need neither be genus-zero nor two-manifolds. We present a new algorithm for decomposing ...

• Hardware Accelerated Interactive Vector Field Visualization: A level of detail approach 

  Bordoloi, Udeepta; Shen, Han-Wei (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  This paper presents an interactive global visualization technique for dense vector fields using levels of detail. We introduce a novel scheme which combines an error-controlled hierarchical approach and hardware acceleration ...

• Designing 2D Vector Fields of Arbitrary Topology 

  Theisel, H. (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  We introduce a scheme of control polygons to design topological skeletons for vector fields of arbitrary topology. Based on this we construct piecewise linear vector fields of exactly the topology specified by the control ...

• Free-form sketching with variational implicit surfaces 

  Karpenko, Olga; Hughes, John F.; Raskar, Ramesh (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  With the advent of sketch-based methods for shape construction, there's a new degree of power available in the rapid creation of approximate shapes. Sketch [Zeleznik, 1996] showed how a gesture-based modeler could be used ...

• Hardware-Based Volumetric Knit-Wear 

  Daubert, Katja; Seidel, Hans-Peter (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  We present a hardware-based, volumetric approach for rendering knit wear at very interactive rates. A single stitch is represented by a volumetric texture with each voxel storing the main direction of the strands of yarn ...

• A Biologically-Parameterized Feather Model 

  Streit, L.; Heidrich, W. (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  Feathers, unlike other cutaneous appendages such as hair, fur, or scales have a definite structure. Variation in feather structure creates a wide range of resulting appearances. Collectively, feather structure determines ...

• Advanced Radiance Estimation For Photon Map Global Illumination 

  Hey, Heinrich; Purgathofer, Werner (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  We present a new method to compute radiance in photon map based global illumination simulation for polygonal scenes with general bidirectional scattering distribution functions (BSDFs). Our new radiance estimation uses the ...

• Grid Based Final Gather for Radiosity on Complex Clustered Scenes 

  Scheel, Annette; Stamminger, Marc; Seidel, Hans-Peter (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  Radiosity methods handle large scenes and complex objects using clustering techniques. To reconstruct a high quality image, usually a second very time consuming final gather pass is applied which exactly recomputes the ...

• Efficient Multidimensional Sampling 

  Kollig, Thomas; Keller, Alexander (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  Image synthesis often requires the Monte Carlo estimation of integrals. Based on a generalized concept of stratification we present an efficient sampling scheme that consistently outperforms previous techniques. This is ...

• Intrinsic Parameterizations of Surface Meshes 

  Desbrun, Mathieu; Meyer, Mark; Alliez, Pierre (Blackwell Publishers, Inc and the Eurographics Association, 2002)

  Parameterization of discrete surfaces is a fundamental and widely-used operation in graphics, required, for instance, for texture mapping or remeshing. As 3D data becomes more and more detailed, there is an increased need ...

• A Simple and Robust Mutation Strategy for the Metropolis Light Transport Algorithm
