Learn about key Bifrost concepts.
- [Narrator] Before getting our proverbial feet wet in Mya,…let's look at the concepts underlying Bifrost.…Bifrost is a general procedural framework…under development at Autodesk.…It has its roots in a liquid simulation plugin…that was called Naiad.…In 2012 Autodesk acquired Naiad and hired its developers.…The stated goal has always been…to develop Bifrost beyond liquid simulation…into a full-featured framework…for procedural content generation…reminiscent of Softimage Ice or 3ds Max MCG.…
Bifrost is an English corruption of an old Norse word,…Bifrost, which is the rainbow bridge…between earth and Asgard, or heaven.…The name was chosen for this technology…because Bifrost is a computation server…that runs inside of but independently of…the host application, such as Mya.…The proverbial rainbow bridge…is the connection between the host app…and the computation server.…The first module that we see developed…within the Bifrost framework is Bifrost Fluids,…which is a so-called FLIP solver.…
FLIP stands for fluid implicit particles.…
