Makoto Chiba has posted an interesting thread on CG Society testing the waters (pun intended) for a new PIC/FLIP/APIC based Fluid simulation tool named Aquarius. The software was original developed as an in-house solution by MagicPictures Inc., but according to the thread, it could soon be released for sale to the wider community. Screen shots show the application running in 3DS Max, but Makoto has mentioned that it is Python-based so any DCC can be used by creating a connector plugin. Simulations are compatible with a number of renderers as Aquarius is able to export data in prt, Alembic and VDB formats.
