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 ... -
Using pre-integrated Transfer Functions in an Interactive Software System for Volume
(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 ... -
View Interpolation for Dynamic Scenes
(Eurographics Association, 2002)This paper describes a novel technique for synthesizing a dynamic scene from two images without the use of a 3D model. A scene containing rigid or non-rigid objects, in which each object can move in any orientation or ... -
Visibility Preprocessing Using Spherical Sampling of Polygonal Patches
(Eurographics Association, 2002)A technique is presented that permits fast view-reconstruction of individual objects. This method improves a previous approach to solve the problem of approximated view reconstruction by combining clustering of polygons ... -
Visual Data Mining
(Eurographics Association, 2002)Never before in history has data been generated at such high volumes as it is today. Exploring and analyzing the vast volumes of data has become increasingly difficult. Information visualization and visual data mining can ... -
The Voronoi-Quadtree: construction and visualization
(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, ...
