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 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:

Types Fluid Effect

 Dynamic fluid effects

 Oceans and Ponds

 Non-dynamic fluid effects

OVERVIEW FLUID EFFECT

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.

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.

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.

What does fluid effects support ?

 Naver Stokes based Fluids

Maya Fire

OVERVIEW FLUID EFFECT Maya Ocean

 2D height field – no crashing waves

 Can attach ‘bouyant’ objects

OVERVIEW FLUID EFFECT Maya Pond

 2D height field

o No splashing

 Mass-spring system

 Bouys, Boats, Wakes

 Can run in real-time
