ZENO is an open-source, Node based 3D system able to produce
cinematic physics effects at High Efficiency, it was designed
for large scale simulations and has been tested on complex
setups. Aside of its simulation Tools, ZENO provides necessary
visualization nodes for users to import and run simulations if
you feel that the current software you are using is too slow.
