Fluid Effect
1) OVERVIEW FLUID EFFECT

OVERVIEW FLUID EFFECT
What is Fluid Effect ?
 Is a technology for realistically simulating and rendering fluid motion. Fluid Effects lets you create a
wide variety of 2D and 3D atmospheric, pyrotechnic, space, and liquid effects.
o You can use the Fluid Effectssolvers to simulate these effects, or you can use fluid animated
textures for more unique, distinguishing effects.
o Fluid Effects also includes an ocean shader for creating realistic open water. You can float
objects on the ocean surface and have those objects react to the motion of the water.
o You can create the following types of effects with Fluid Effects:


OVERVIEW FLUID EFFECT
Types Fluid Effect
 Dynamic fluid effects
Behave according to the natural laws of fluid dynamics, a branch of physics that uses
mathematical equations to calculate how things flow. Maya simulates fluid motion by
solving the Navier-Stokes fluid dynamics equations at each time step.

 Non-dynamic fluid effects
3D fluids inherently require extra data to define them, which can make them very large.
This extra data can slow a dynamic simulation exponentially because more calculations
(solving) must be performed at every step of the simulation. For a less memory intensive
effect, you can use a 2D fluid (with less data), or you can create a non-dynamicfluid.

 Oceans and Ponds
Create Ocean and Pond fluids to simulate large realistic water surfaces, such as stormy
oceans with foam and swimming pools. Oceans are NURBS planes with ocean shaders
assigned to them. Ponds are 2D fluids that use a spring mesh solver and a height field.
