PhysX Research: Wrinkle Meshes
Dr. Matthias MÃ¼ller-Fischer, PhysX SDK research lead at Nvidia Switzerland, Novodex founder and man behind many core PhysX algorithms, like Position Based Dynamics solver for cloth and soft-bodies, has published another interesting paper ' Wrinkle Meshes.
We present a simple and fast method to add wrinkles to dynamic meshes such as simulated cloth or the skin of an animated character. To get the desired surface details, we attach a higher resolution wrinkle mesh to the coarse base mesh allowing the wrinkle vertices to deviate from their attachment positions within a limited range. The shape of the wrinkle mesh is determined by a static solver which runs in parallel to the motion of the base mesh. Our method can be used to automatically enhance a purely animated skin mesh with wrinkles which would be atedious task to do by hand.
In generally, that means more detailed cloth simulation with less resourse consumption. Previous research ' Hierarchical Position Based Dynamics ' was already added in PhysX SDK 2.8.3 so we believe that Wrinkle Meshes will appear in PhysX SDK or APEX Clothing module soon enough.
