An Incremental SMLAOI Algorithm for Progressive Downloading Large Scale WebVR Scenes
(The Eurographics Association, 2009)
Interactive downloading huge virtual scenes on Internet is always a challenging task of large scale DVE(Distributed Virtual Environment) systems. Along classical progressive transmission mechanism based on AOI (Area of ...
RTSG: Ray Tracing for X3D via a Flexible Rendering Framework
(The Eurographics Association, 2009)
VRML and X3D are the most widely adopted standards for interactive 3D content interchange. However, they are both designed around the common restricted functionality available in hardware graphics processors. Thus, most ...
GPU-based Real-time On-surface Droplet Flow in X3D
(The Eurographics Association, 2009)
This paper presents a method for the GPU-based real-time simulation of droplet flows on 3D surfaces. It is also outlined, how this approach can be embedded into X3D. Therefore, a concept and its implementation is presented, ...
Proposed Enhancements to the X3D Geospatial Component
(The Eurographics Association, 2009)
The Geospatial Component of the X3D Standard suffers from some deficiencies that prevent its wider adoption. This paper addresses two of these deficiencies. The first problem is that in order to reduce spatial jitter content ...
A Model-Based Approach to Image Relighting with a Potential for Real-Time Implementation
(The Eurographics Association, 2005)
Image relighting is a very unique special visual effect which promises to have many important practical applications. Image relighting is essentially the process of, given one or more images of some scene, computing what ...
Real-Time Capture, Reconstruction and Insertion into Virtual World of Human Actors
(The Eurographics Association, 2003)
In this paper, we show how to capture an actor with no intrusive trackers and without any special environment like blue set, how to estimate its 3D-geometry and how to insert this geometry into a virtual world in real-time. ...
Adaptive Grid Optical Tomography
(The Eurographics Association, 2005)
Image-based modeling of semi-transparent, dynamic phenomena is a challenging task. We present an optical tomography method that uses an adaptive grid for the reconstruction of a three-dimensional density function from its ...
Texture Mapping Volume Objects
(The Eurographics Association, 2005)
We present a combination of image-based texture mapping and projective space (pseudo-solid) texture. This imagebased texture mapping is useful for objects defined from volume datasets. The paper makes three main contributions. ...
Extending X3D for Distributed Multimedia Processing and Control
(The Eurographics Association, 2009)
Web-based applications of interactive 3D computer graphics are showing a tendency to get more interconnected and visually complex. Virtual communities like Second Life demand realism not only in terms of realistic rendering, ...
Regularised Anisotropic Nonlinear Diffusion for Rendering Refraction in Volume Graphics
(The Eurographics Association, 2005)
Rendering refraction in volume graphics requires smoothly distributed normals to synthesise good quality visual representations. Such refractive visualisation is more susceptible to noise in the data than visualisations ...
