NVIDIA revealed some of the capabilities of its upcoming PhysX FleX engine, a particle-based simulation technique for real-time visual effects. In the video clip below you can see a cereal simulation that models two way coupling of cereal represented by rigid bodies with particle-based fluid simulation. The mik features up to 100,000 particles, it's rendered in real-time using ellipsoid splatting and a sub-surface scattering approximation. In the clip you can see the surface tension and viscous forces, as well as how the cereal naturally rises to the surface due to buoyancy as they have a lower density than the milk.
The second part of the video is a smoke simulation, it simulates realistic smoke as well as the interaction with rigid and cloth objects.
PhysX FleX is currently in closed beta and available for early adopters. NVIDIA is also working on a UE4 integration.
PhysX FleX is a particle based simulation technique for real-time visual effects. So far we showed examples for rigid body stacking, particle piles, soft bodies and fluids. In this video we'll be showing some of the new advancements within PhysX FleX.
