Real-time Interactive Simulation of Smoke Using Discrete Integrable Vortex Filaments
(The Eurographics Association, 2009)
We present a fluid solver for the real-time interactive simulation of inviscid, ideal fluid flow. The simulation is based on the evolution of discrete vortex filaments, which allow a dramatic increase of detail and performance ...
Web Based Presentation of Semantically Tagged 3D Content for Public Sculptures and Monuments in the UK
(The Eurographics Association, 2009)
The documentation and presentation of 3D digital content is a critical but non-trivial task for the Cultural Heritage sector. Curators are often faced with the task of cataloguing every piece of heritage and maintaining ...
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 ...
Optimized Impulse-Based Dynamic Simulation
(The Eurographics Association, 2009)
The impulse-based dynamic simulation is a recent method to compute physically based simulations. It supports the simulation of rigid-bodies and particles connected by all kinds of implicit constraints. In recent years the ...
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, ...
Design of Dynamical Stability Properties in Character Animation
(The Eurographics Association, 2009)
Human movements and the collective behavior of interacting characters in crowds can be described by nonlinear dynamical systems. The design of stability properties of dynamical systems has been a core topic in control ...
Smoke Simulation for Fire Engineering using a Multigrid Method on Graphics Hardware
(The Eurographics Association, 2009)
We present a GPU-based Computational Fluid Dynamics solver for the purpose of fire engineering. We apply a multigrid method to the Jacobi solver when solving the Poisson pressure equation, supporting internal boundaries. ...
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 ...
3D Modeling in a Web Browser to Formulate Content-Based 3D Queries
(The Eurographics Association, 2009)
We present a framework for formulating domain-dependent 3D search queries suitable for content-based 3D search over the web. Users are typically not willing to spend much time to create a 3D query object. They expect to ...
