Here are the key features of PhysX 5.0. The Finite Element Model (FEM): an industry-standard simulation technique for deformable bodies. It is used extensively in the automotive and manufacturing industries to accurately simulate the structural strength of both rigid and soft assemblies. Liquid simulations: Developers will be able to use discrete particle simulations to model granular flow. The implementation is scalable; robust-to-large time-steps can be used to stably simulate a wide range of liquids. Arbitrary meshes: These can be simulated as cloth or rope using PhysX 5.0’s constrained particle model. These meshes can be coupled with volume preservation constraints with application-defined pressures to simulate inflatable shapes. The mesh-based simulations also provide a model to simulate aerodynamic drag and lift. The constraint model supports springs so it can be used to create mass-spring systems.
