Modeling and Rendering of Synthetic Plants
(Eurographics Association, 2002)Plant geometries: → important for many indoor and outdoor scenes → hard to generate and to manipulate → tricky to convert → today: seldomly used → tomorrow: standard of most animation systems -
Modeling Visual Attention in VR: Measuring the Accuracy of Predicted Scanpaths
(Eurographics Association, 2002)Dynamic human vision is an important contributing factor to the design of perceptually-based Virtual Reality. A common strategy relies on either an implicit assumption or explicit measurement of gaze direction. Given the ... -
More than RGB: Spectral Trends in Color Reproduction
(Eurographics Association, 2002)Early rendering algorithms relied exclusively on three-dimensional spaces for color computation, such as RGB and CIE XYZ. Recent rendering advances use full spectral information for illuminants and surfaces, resulting in ... -
Multi-dimensional and Multi-scale Visualizer of Large XML Documents
(Eurographics Association, 2002)3D-XV (3-Dimensional XML Visualizer) is an interactive graphical interface for accessing large structured documents. It relies on a geometrical model that combines a sequential organization and a hierarchical structure. ... -
Normal Enhancement for Interactive Non-photorealistic Rendering
(Eurographics Association, 2002)We present a simple technique to improve the perception of shape of an object. Bump mapping is well-known in the computer graphics community for providing the impression of small-scale geometrical features (which actually ... -
On the Integration of Synthetic Objects with Real-World Scenes
(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 ... -
Real-time 3D Deformations by Means of Compactly Supported Radial Basis Functions
(Eurographics Association, 2002)We present an approach to real-time animation of deformable objects. Optimization of algorithms using compactly supported radial basis functions (CSRBF) allows us to generate deformations performed fast enough for such ... -
Real-Time Animated Grass
(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 ... -
Rendering Artistic Line Drawings Using Off-the-Shelf 3-D Software
(Eurographics Association, 2002)Most commercial 3-D software packages used for animated films and still picture production offer merely rudimentary support for non-photorealistic rendering. However, nearly all of these packages possess interfaces which ... -
Rendering of Japanese Artcraft
(Eurographics Association, 2002)We present several methods for simulation of Japanese lacquer ware, a prominent Far East Asian handicraft art. We consider two most popular kinds of Japanese lacquer ware made by the makie and nashiji techniques. For ... -
Reverse Diffusion for Smooth Buildup of Progressivly Transmitted Geometry
(Eurographics Association, 2002)In this paper we consider 3D object surfaces which can be represented as scalar functions defined on the sphere. These objects can be modeled as series of spherical harmonic functions. A simple progressive transmission ... -
SAVANT: A new efficient approach to generating the visual hull
(Eurographics Association, 2002)We present a new approach to generating a boundary representation (a polygonal mesh) of the visual hull from a set of silhouettes of an object taken from known camera positions. The approach uses spatial subdivision to ... -
Simulation of Cumuliform Clouds Based on Computational Fluid Dynamics
(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 ... -
Texture Mapping on Doo-Sabin Subdivision Surfaces Using Multiple Images
(Eurographics Association, 2002)We propose a texture mapping method on subdivision surfaces using multiple images and have implemented it on Doo- Sabin scheme. At the beginning, one texture map is specified for each control mesh face respectively. In a ... -
Texture Minification using Quad-trees and Fipmaps
(Eurographics Association, 2002)The paper extends the recently published methods for image reconstruction and texture minification using the generalized ripmap method, named fipmap, and quad-trees. Fipmap is based on the technique of partitioned iterated ... -
Texturing Calibrated Head Model from Images
(Eurographics Association, 2002)In this paper we address a well-known problem of producing an animated model of a human head from a pair of orthogonal photographs and present a new technique of generating consistent high-quality texture for a polygonal ... -
Tone Reproduction and Physically Based Spectral Rendering
(Eurographics Association, 2002)The ultimate aim of realistic graphics is the creation of images that provoke the same responses that a viewer would have to a real scene. This STAR addresses two related key problem areas in this effort which are located ... -
Tree balancing for mesh simplification
(Eurographics Association, 2002)In this paper, a tree balancing technique is presented that reduces the number of hierarchy levels in typical paircontraction based mesh simplification methods. A well-balanced hierarchy is essential for data structures ...
