We present a new hybrid CPU/GPU collision detection technique for rigid and deformable objects based on spatial subdivision. Our approach efficiently exploits the massive computational capabilities of modern CPUs and GPUs commonly found in off-the-shelf computer systems. The algorithm is … Continue reading →

By modeling mass transfer phenomena, we simulate solids and liquids dissolving or changing to other substances.We also deal with the very small-scale phenomena that occur when a fluid spreads out at the interface of another fluid. We model the pressure … Continue reading →

The visual simulation of natural phenomena has been widely studied. Although several methods have been proposed to simulate melting, the flows of meltwater drops on the surfaces of objects are not taken into account. In this paper, we propose a … Continue reading →

In this paper we introduce a novel parallel and interactive SPH simulation and rendering method on the GPU using CUDA which allows for high quality visualization. The crucial particle neighborhood search is based onZ-indexing and parallel sorting which eliminates GPU … Continue reading →

The papers program for VRIPHYS 2010 (VRIPHYS = Virtual Reality Interaction and Physical Simulation) has recently been posted here.

We present a simple technique for creating fluid silhouettes described with vector graphics, which we call “Vector Fluid.” In our system, a solid region in the fluid is represented as a closed contour and advected by fluid flow to form … Continue reading →

We present a method for directly modeling piles of objects in multibody simulations. Piles of objects represent some of the more interesting, but also most time-consuming portion of simulation. We propose a method for reducing computation in many of these … Continue reading →

This paper introduces a fully-Eulerian interface tracking framework that preserves the fine details of liquids. Unlike existing Eulerian methods, the proposed framework shows good mass conservation even though it does not employ conventional Lagrangian elements. In addition, it handles complex … Continue reading →
