Houdini is a somewhat complex (and expensive) beast to get to grips with, but it's an absolute powerhouse if you need your fluids to interact with other elements such as soft- and rigid-body dynamics. ![]() On combination smoke and carbon monoxide detectors, press and release the test button, and the signal will go from unit to unit testing the interconnect circuitry as well as the alarm. Houdini also has a dedicated Ocean FX simulator for making seas, beaches, waves and so on, combined with a new ocean material for more authentic looking sims. On smoke only models, the sound will stop immediately once your finger is removed from the test button. It also has a new surfacer – the operator which generates the liquid object from the particle source – which produces smoother surfaces and better 'sheeting', the thin layers of fluid held together by surface tension. Release 13 of the procedural VFX app Houdini features an updated version of its FLIP (fluid-implicit particle) solver, which is faster and more accurate, and allows the creation of mist as well as foam, spray and bubbles. Houdini 13 features an updated version of its FLIP (fluid-implicit particle) solver Bifröst is already a very impressive fluid simulation system, with more yet to come. However it does have the ability to produce velocity fields from displaced geometry and have that affect the particles, to produce rolling waves, for example. It's capable of handling tens of millions of particles for large-scale fluid simulations, although it doesn't yet create foam and spray. A year later, Naiad resurfaced as Bifröst – the procedural effects platform in Maya 2015. Naiad never even made it to version 1.0 before Autodesk bought the technology in August 2012. ![]() Although unfinished, the technology was employed as a dedicated tool for VFX studios and was used in films including Avatar, X-Men first Class, Rise of the Planet of the Apes. One app that caused quite a stir in the fluid scene was Naiad from Exotic Matter, which first appeared around 2009 in some mazing SIGGRAPH tech demos. Bifröst is capable of handling tens of millions of particles for large-scale fluid simulations ![]()
