1) OVERVIEW FLUID EFFECT

Fluid Effect

What is Fluid Effect ?

OVERVIEW FLUID EFFECT

Is a technology for realistically simulating and rendering fluid motion. Fluid Effects lets you create awide 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:

Types Fluid Effect

Dynamic fluid effects

Oceans and Ponds

Non-dynamic fluid effects


Behave according to the natural laws of fluid dynamics, a branch of physics that usesmathematical equations to calculate how things flow. Maya simulates fluid motion bysolving the Navier-Stokes fluid dynamics equations at each time step.

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 intensiveeffect, you can use a 2D fluid (with less data), or you can create a non-dynamicfluid.

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