CREATE ABSTRACT SIMULATIONS USING BIFROST FLUIDS

Holly Watt demonstrates how to set up and manipulate liquid simulations in Maya

Bifrost Fluids is known for its capability to recreate real-world liquid simulations such as oceans, but it can also be a useful tool in creating abstract fluid simulations. The added bonus is that it is a free plug-in with Autodesk Maya, so there is no need to leave the Maya software in order to create these types of fluid simulations. This tutorial covers the process of setting up and manipulating Bifrost Fluids that morph from one shape mesh to another, giving a zero-gravity effect. An overview is given on how to set up the initial Bifrost Fluid simulation, tweak the liquid properties, caching and finally rendering.

Motion Fields in Bifrost Fluids have the ability to control the particles’ movements and velocities, and this tutorial uses the Along Normal attribute to conform the particles to the shape of a mesh. We will cover how to add a Motion Field and how to use it to manipulate particles to morph between two meshes. With this knowledge you will also be able to apply the Along Normal attribute to achieve other effects, such as using geometry to control the directional movement of a liquid or to have liquid return to its original form after a collider has passed through it.
