  This paper presents a multi-phase algorithm to solve the global illumination problem. In the first phase dependent tests are applied, i.e. the random walks of different pixels are built from the same random numbers. The ...

• On the Integration of Synthetic Objects with Real-World Scenes 

  Abad, Francisco; Camahort, Emilio; Vivó, Roberto (Eurographics Association, 2002)

  This paper presents a method for integrating synthetic objects in real-world photographs. We take a set of photographs of a real scene and build a simple image-based model. We use high dynamic range images to build an ...

• Using pre-integrated Transfer Functions in an Interactive Software System for Volume 

  Knittel, Guenter (Eurographics Association, 2002)

  We explore possibilities to implement classification based on pre-integrated transfer functions in a software system for high-speed volume rendering. The major obstacle to remove is the large size of the multi-dimensional ...

• The Voronoi-Quadtree: construction and visualization 

  Coll, Narcís; Boada, Imma; Sellares, J.A. (Eurographics Association, 2002)

  We define a quadtree-based planar Voronoi diagram codification, the Voronoi-Quadtree, valid for generalized sites (points, line-segments, curve-arc segments, ...) and for different distance functions (Euclidean metrics, ...

• Simulation of Cumuliform Clouds Based on Computational Fluid Dynamics 

  Miyazaki, Ryo; Dobashi, Yoshinori; Nishita, Tomoyuki (Eurographics Association, 2002)

  Simulation of natural phenomena is one of the important research fields in computer graphics. In particular, clouds play an important role in creating images of outdoor scenes. Fluid simulation is effective in creating ...

• Extraction of Critical Points and Nets Based on Discrete Gradient Vector Field 

  De Floriani, Leila; Mesmoudi, Mohammed Mostefa; Danovaro, Emanuele (Eurographics Association, 2002)

  In this paper we address the problem of representing the topology of discrete scalar fields defined on triangulated domains. To this aim, we use the notion of discrete gradient vector field that we have introduced in [4] ...

• Concise Tour to the Virtual Old Prague 

  Zara, Jiri (Eurographics Association, 2002)

  This paper describes a structure and a user interface of the Internet based 3D presentation of existing historical part of city Prague. The application offers a smooth tour to selected regions of the real city, utilizing ...

• Dynamic Motion Models 

  Grünvogel, Stefan Michael; Lange, Thorsten; Piesk, Jens (Eurographics Association, 2002)

  Real-time animation of virtual characters is a demanding task. We propose dynamic motion models which can create the motion of a virtual character in different styles and have the ability to change the animation while it ...

• Dynamics-Based Motion Synthesis by Simple Learning Control 

  Kiriazov, Petko (Eurographics Association, 2002)

  Point-to-point motion of a humanoid agent (or any mobile creature) is considered as a composition of basic movements related to the degrees of freedom. With time/energy performance criteria, such movements can be synthesized ...

• A Method for Creating Mosaic Images Using Voronoi Diagrams 

  Dobashi, Yoshinori; Haga, Toshiyuki; Johan, Henry; Nishita, Tomoyuki (Eurographics Association, 2002)

  This paper proposes a non-photorealistic rendering method that creates an artistic effect called mosaicing. The proposed method converts images provided by the user into the mosaic images. Commercial image editing applications ...

• Distance fields applied to character animation 

  Rudomin, Isaac; Castillo, J. (Eurographics Association, 2002)

  A general hybrid geometric-physical method that is useful for animating characters with skin, clothing and a MPEG-4 compatible face is presented. This method uses an approximation to the underlying musculo-skeletal structure ...

• Real-Time Animated Grass 

  Bakay, Brook; Lalonde, Paul; Heidrich, Wolfgang (Eurographics Association, 2002)

  We present a simple method to render fields of grass, animated in the wind, in real-time. The technique employs vertex shaders to render displacement maps with Russian-doll style transparent shells. Animation is achieved ...

• Improved Integration for Cloth Simulation 

  Parks, David L.; Forsyth, David A. (Eurographics Association, 2002)

  Most methods of cloth simulation produce animations that do not move very freely; the result often looks like the material is “swimming”. The primary sources of this phenomenon are the non-physical dissipation terms often ...

• Digital Watermarking for Volumetric Datasets 

  Dimitrov, Leonid I.; Sramek, Milos (Eurographics Association, 2002)

  An idea for digitaly watermarking volumetric datasets (VDS) and preliminary results from a test implementation are presented. It consists of a combination of filtering and rendering operations on volumetric data allowing ...

  Remolar, Inmaculada; Chover, Miguel; Belmonte, Oscar; Ribelles, Jose; Rebollo, Cristina (Eurographics Association, 2002)

  One of the most important challenges in real-time rendering of outdoor scenes is the representation of vegetation. This is due to the vast amount of polygons that are used to model vegetable species. The present automatic ...

• Mesh Decimation for Displacement Mapping
