Abstract
We propose an approach to simulating and rendering physically based fluid effects in a VFX production environment
using a client/server architecture that is practical for distributed simulation resources and that can be
seamlessly integrated into commercial 3D animation packages. The fluid simulation implements smoothed particle
hydrodynamics (SPH). We extend the concept of surface particles by introducing blind particles that facilitate
efficient direct raytracing of isosurfaces. We evaluate the performance of our approach with local simulation on
CPUs and GPUs and distributed GPU simulation. We demonstrate the integration into the animation package
3ds Max and the VRay raytracer. The usability of the VFX production pipeline is assessed by a user study with
VFX professionals and animation experts.
