My colleague implemented a Disney MPM Snow mock paper, and I ported it to Maya with the title of a material point method for snow simulationHere's the code: Https://github.com/league1991/MpmMayaThe plug-in leverages the OPENVDB library to output OPENVDB data, which can then be used to generate mesh rendering with OPENVDB. Using TBB for CPU parallelism, combined with C11 lambda expression, TBB programming is very convenient, basically do not need to ma
