A Real Time Light Probe
(Eurographics Association, 2004)We present a novel system capable of capturing high dynamic range (HDR) Light Probes at video speed. Each Light Probe frame is built from an individual full set of exposures, all of which are captured within the frame time. ... -
Virtual Clay for Direct Hand Manipulation
(Eurographics Association, 2004)In order to make virtual modeling as easy as real clay manipulation, we describe a realtime virtual clay model, specially designed for direct hand manipulation. We build on a previous layered model for clay, extending it ... -
Modulating View-dependent Textures
(Eurographics Association, 2004)We present a texturing approach for image-based modeling and rendering, where instead of using one (or a blend of a few) sample images, new view dependent textures are synthesized by modulating a differential texture basis. ... -
Modeling clouds shape
(Eurographics Association, 2004)We propose a model for representing the shape of cumulus clouds.We draw on several approaches that we combine and extend: We store a hierarchy of quasi-spherical particles (or blobs) living on top of each other. The shape ... -
A Web-Based Multimedia Virtual Reality Environment for E-Learning
(Eurographics Association, 2004)The past decade has seen major advances in the availability of broadband computer access. With this everincreasing connection speed and improved Internet performance more and more web-based applications are becoming ... -
Frontier Sets: A Partitioning Scheme to Enable Scalable Virtual Environments
(Eurographics Association, 2004)We present a new spatial partitioning scheme called frontier sets. Frontier sets build on the notion of a potentially visible set (PVS) [ARB90, TS91]. In a PVS a world is sub-divided into cells and for each cell all the ... -
Adaptive Brush Stroke Generation for Painterly Rendering
(Eurographics Association, 2004)We propose adaptive brush stroke generation for source images, using reference data. Colors used are formed by actual palette colors from artists. To create the palette, we have referred mostly to colors used in Van Gogh’s ... -
Interactive Physically-based Animation System for Dense Meshes
(Eurographics Association, 2004)In this paper we describe an interactive physically-based animation system for dense meshes. Our method extracts a coarse mesh from an original mesh to make a tetrahedral mesh for the reduction of computational costs. For ... -
A Spectral Gamut-Mapping Environment with Rendering Parameter Feedback
(Eurographics Association, 2004)This paper proposes a prototypical environment for gamut mapping in spectral space. Images are rendered in terms of light and material parameters by a symbolic ray tracer, and the parameter ranges are adjusted, without ... -
Steerable Texture Synthesis
(Eurographics Association, 2004)Texture synthesis is typically concerned with the creation of an arbitrarily sized texture from a small sample, where the pattern of the generated texture should be perceived as resembling the example. Most of the current ... -
Interactive Modeling of Mushrooms
(Eurographics Association, 2004)This paper presents a fast and efficient method for modeling mushrooms. Starting from a real world image, the designer defines a silhouette and specifies deformation parameters. Our system then automatically generates a ... -
An Oriented Particle and Generalized Spring Model for Fast Prototyping Deformable Objects
(Eurographics Association, 2004)We present a new mass-spring system, in particular, by using an oriented particle and generalized spring model, which can be used for fast prototyping or animation of deformable objects. Conventional mass-spring system is ... -
The Visualisation and Expression of Virtual 3DSurfaces Explored through Custom Developed Interactive Software, Optically Mixed Coloured Surface Contouring and Fine Art Printmaking
(Eurographics Association, 2004)This short presentation paper describes an exploration and the visualisation of virtual 3D compositions through custom developed software and fine art printmaking. The author, a trained and practising visual artist considers ... -
Enriching Animation Databases
(Eurographics Association, 2004)The paper presents a framework for enriching an existing basic animation databse by modifying existing motions to generate a variety of new motions. Intuitively controlled motion varities are generated on demand which ... -
Realtime Isosurface Extraction with Graphics Hardware
(Eurographics Association, 2004)In this paper we introduce a method for the display of isosurfaces extracted from unstructured tetrahedral grids. Our algorithm completely runs on the graphics hardware. The tetrahedra are streamed into a vertex program, ... -
Visual Model of Fire
(Eurographics Association, 2004)This paper presents a fire model based on dynamic particle chains. The chains are shaped and moved by a varying velocity field and constitute a density field, which is rendered using the ray tracing method. What we want ... -
SP-Octrees Visualization Using Impostors
(Eurographics Association, 2004)SP-Octrees (Space-Partition Octrees) allow a multiresolution representation of polyhedral objects, and have been successfully used in progressive transmission. Nonetheless, the SP-Octree is a solid modeling structure, ... -
A Generic Method for Geometric Contraints Detection
(Eurographics Association, 2004)In this paper, we present a generic method to automatically detect geometric constraints on motion capture animations. At each frame, elementary geometric constraints are computed with respect to a reference which can ... -
A Color Decomposition Method for Preserving Ukiyo-e Woodblocks
(Eurographics Association, 2004)In this paper we propose a color decomposition method for multicolor printing of watercolors including areas overlapping each print layer. Watercolors have an important feature that the observed colors are different on the ... -
Tone Mapping in VR Environments
(Eurographics Association, 2004)Tone mapping is the process of mapping high dynamic range images to the low dynamic range of current displays. So far, tone mapping research was focused on static images, but with powerful graphics hardware available today, ...
