Grid-Free Surface Tracking on the GPU
(The Eurographics Association, 2015)We present the first mesh-based surface tracker that runs entirely on the GPU. The surface tracker is both completely grid-free and fast which makes it suitable for the use in a large, unbounded domain. The key idea for ... -
A More Efficient Parallel Method For Neighbour Search Using CUDA
(The Eurographics Association, 2015)In particle systems simulation, the procedure of neighbour searching is usually a bottleneck in terms of computational cost. Several techniques have been developed to solve this problem; one of particular interest is the ... -
Accurate Contact Modeling for Multi-rate Single-point Haptic Rendering of Static and Deformable Environments
(The Eurographics Association, 2015)Common approaches for the haptic rendering of complex scenarios employ multi-rate simulation schemes. Here, the collision queries or the simulation of a complex deformable object are often performed asynchronously on a ... -
Level-of-Detail Modal Analysis for Real-time Sound Synthesis
(The Eurographics Association, 2015)Modal sound synthesis is a promising approach for real-time physically-based sound synthesis. A modal analysis is used to compute characteristic vibration modes from the geometry and material properties of scene objects. ... -
Vascular Neurosurgery Simulation with Bimanual Haptic Feedback
(The Eurographics Association, 2015)Virtual surgical simulators face many computational challenges: they need to provide biophysical accuracy, realistic feed-backs and high-rate responses. Better biophysical accuracy and more realistic feed-backs (be they ... -
A New Force Model for Controllable Breaking Waves
