Computational physics is the natural framework for such simulations. The physical equations describing most of these phenomena are well known and have been extensively studied over the last couple of centuries by the physics community. Which solution technique to use in practice depends on the application. In computer graphics it is desirable to have fast and stable simulations. Ideally, the simulations should run in realtime. This is important of course in games but also in movie production houses where animators have to fine tune the parameters of the simulation. On the other hand it is also desirable that these simulations are easy to implement. This makes the code easier to maintain in a commercial system. Our experience has been that good solutions very often result in simple algorithms which are relatively easy to code. This paper mainly focuses on the simulation of fluids such as smoke, water and fire. Our fluid solver which was first introduced in Stam (1999) relies on a spatial discretization of space into voxels. The physical quantities describing the fluid such as velocity and density are assumed to be constant in each voxel. These values are updated over each time step to create an animation of a fluid flow.","PeriodicalId":264796,"journal":{"name":"12th Pacific Conference on Computer Graphics and Applications, 2004.

Especially in engineering applications it is crucial to guarantee that a prescribed approximation tolerance to a given reference geometry is respected for any combination of geometric algorithms that are applied when processing a triangle mesh. We propose a simple and generic method for computing the distance of a given polygonal mesh to the reference surface, based on a linear approximation of its signed distance field. Exploiting the hardware acceleration of modern GPUs allows us to perform up to 3M triangle checks per second, enabling real-time distance evaluations even for complex geometries. An additional feature of our approach is the accurate high-quality distance visualization of dynamically changing meshes at a rate of 15M triangles per second. Due to its generality, the presented approach can be used to enhance any mesh processing method by global error control, guaranteeing the resulting mesh to stay within a prescribed error tolerance. The application examples that we present include mesh decimation, mesh smoothing and freeform mesh deformation.","PeriodicalId":264796,"journal":{"name":"12th Pacific Conference on Computer Graphics and Applications, 2004.
