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 OVERVIEW FLUID EFFECT What does fluid effects support ? Naver Stokes based Fluids o Smoke o Clouds o Explosions o Fire o “Goo” type-stuff Ad-Hoc / Mass-Spring fluids o Oceans o Ponds OVERVIEW FLUID EFFECT 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 Fluid Effect 2) WORKING WITH FLUID POND Fluid Effect 3) PRACTICAL SITUATIONS - OCEAN 3.1) Create Ocean 3.2) Preview Plane 3.3) Floating objects 3.4) Adjust Attribute 3.5) Motor Boats 3.6) Ocean Wake PRACTICAL SITUATIONS - FLUID OCEAN 3.4) Adjust Attribute PRACTICAL SITUATIONS - FLUID OCEAN 3.4) Adjust Attribute Fluid Effect 3) PRACTICAL SITUATIONS - OCEAN 3.1) Create Ocean 3.2) Preview Plane 3.3) Floating objects 3.4) Adjust Attribute 3.5) Motor Boats 3.6) Ocean Wake PRACTICAL SITUATIONS - FLUID OCEAN 3.5) Motor Boats Fluid Effect 3) PRACTICAL SITUATIONS - OCEAN 3.1) Create Ocean 3.2) Preview Plane 3.3) Floating objects 3.4) Adjust Attribute 3.5) Motor Boats 3.6) Ocean Wake PRACTICAL SITUATIONS - FLUID OCEAN 3.6) Ocean Wake Fluid Effect 4) WORKING WITH VISOR LIBRARY PRACTICAL SITUATIONS - FLUID OCEAN What is Visor Library ? To open the Visor: o In main menu bar: Editors > General Editors > Visor o In scene view: Panels > Panel > Visor WORKING WITH VISOR LIBRARY Using Visor: Step 1: Open Visor Step 2: Select type effect template Step 3: Drag and drop to screen view Step 4: Edit template WORKING WITH VISOR LIBRARY Using Visor: 2.1 2.2 2.3 WORKING WITH VISOR LIBRARY Example : Create fire for a virtual lab WORKING WITH VISOR LIBRARY How to create it ?
