A developer called Makoto Chiba has presented a new PIC/FLIP/APIC based fluid simulation tool.
The toolkit has been tested in 3DS Max, but it is Python-based, so there could be more to it. Aquarius can export data in prt, Alembic and VDB formats.
Aquarius is an original application designed to create smooth and realistic fluid water animations. Compared to existing particle-based fluid simulators which cause artificial bounce, Aquarius produces high quality visual effects of fluid movements without visual loss of volume. In addition, unlike Blob, it does not generate unnatural splash or roundness in the liquid surface.
Aquarius can create high quality effects through control of various characteristics such as liquid flow, splash, bubble, vortex, viscosity, collision, and external forces.
Magicpictures,Inc. utilizes Aquarius to provide dynamic fluid animation and any other CG animations services. For further information, please contact us.
