GPU Accelerated Pathfinding
(The Eurographics Association, 2008)
In the past few years the graphics programmable processor (GPU) has evolved into an increasingly convincing computational resource for non graphics applications. The GPU is especially well suited to address problem sets ...
Image Space Gathering
(The Eurographics Association, 2009)
Soft shadows, glossy reflections and depth of field are valuable effects for realistic rendering and are often computed using distribution ray tracing (DRT). These blurry effects often need not be accurate and are sometimes ...
Tangible 3D: Hand Gesture Interaction for Immersive 3D Modeling
(The Eurographics Association, 2005)
Most of all interaction tasks relevant for a general three-dimensional virtual environment can be supported by 6DOF control and grab/select input. Obviously a very efficient method is direct manipulation with bare hands, ...
ClearPath: Highly Parallel Collision Avoidance for Multi-Agent Simulation
(ACM SIGGRAPH / Eurographics Association, 2009)
We present a new local collision avoidance algorithm between multiple agents for real-time simulations. Our approach extends the notion of velocity obstacles from robotics and formulates the conditions for collision free ...
Experiment-based Modeling, Simulation and Validation of Interactions between VirtualWalkers
(ACM SIGGRAPH / Eurographics Association, 2009)
An interaction occurs between two humans when they walk with converging trajectories. They need to adapt their motion in order to avoid and cross one another at respectful distance. This paper presents a model for solving ...
Guiding of Smoke Animations Through Variational Coupling of Simulations at Different Resolutions
(ACM SIGGRAPH / Eurographics Association, 2009)
We propose a novel approach to guiding of Eulerian-based smoke animations through coupling of simulations at different grid resolutions. Specifically we present a variational formulation that allows smoke animations to ...
Fitting Behaviors to Pedestrian Simulations
(ACM SIGGRAPH / Eurographics Association, 2009)
In this paper we present a data-driven approach for fitting behaviors to simulated pedestrian crowds. Our method annotates agent trajectories, generated by any crowd simulator, with action-tags. The aggregate effect of ...
SteerBug: An Interactive Framework for Specifying and Detecting Steering Behaviors
(ACM SIGGRAPH / Eurographics Association, 2009)
The size of crowds that modern computer games and urban simulations are capable of handling has given rise to the challenging problem of debugging and testing massive simulations of autonomous agents. In this paper, we ...
Fast and Robust Tracking of Fluid Surfaces
(ACM SIGGRAPH / Eurographics Association, 2009)
Surface tracking is an important problem with applications in many research fields. Among the most famous examples in computer graphics is the simulation and rendering of liquids with free surfaces. A surface that is ...
