阿凡达流体Naiad 软件CMIVFX机构最新教学

cmiVFX releases the "first ever" Naiad training video, continuing the long streak of "first ever" inventions, processes and techniques the company is well known for. This is the first volume of a series and focuses on entry level to middle level concepts and theory behind this powerful, yet nearly undiscovered software package. This training will teach the viewer the basic principles behind a F.L.I.P. Solver and level sets theory utilizing practical examples.

Chapter Breakdown


 
Introduction
Despite being a relatively new product, Naiad has already been used to produce the 3D fluid animations in several motion-pictures.
 
Naiad is also being used frequently in TV series and commercials. 
 
Anatomy of a body
Naiad fundamentals is the discussion that will kick off this chapter. Learning more about the system as a whole will produce better results then settling on designing for just a single liquid simulation. Diego will take you through the physics of water bodies.
 
Getting started
In this chapter you will learn about the UI and workspace in Nstudio, setup a project folder structure with stat files, and explore a liquid box example scene in the node graph.
 
Introduction to fluid theory
Diego will use slides and notes to explain differences between Computational Fluid Dynamics and Smooth Particles Hydrodynamics solvers.
Lagrangian and Eulerian Viewpoints ( SPH vs. GRID ); F.L.I.P. method and anatomy of a Naiad body: Shapes and Channels, Properties, Tile layout and the "emp" file format (empinfo cmd line tool).
 
Building a fountain graph I
In this chapter you will learn the Naiad buddy export process, combining multiple assets in one(triangle orientation).
 
Building a fountain graph II
Diego will then move on to the sequel chapter, in which you will learn several interests in the fluid pipeline setup such as: Global settings (CFL condition and Cell size), detailed analysis of the simulation graph, particle kill plane, droplet channel, emission ID's, dynamics operators: Acceleration, Friction, Drag, Swirl.
 
Building a fountain graph III
This portion of the video covers the evaluation of a Naiad graph from UI, batch mode or cmd line (detailed description of cmd flags), play blasting from UI and play blasting from cmd line for parallel play blast of scenes on multiple computers.
 
Optimizing simulation time
Learn tips and tricks to optimize simulation for fast turnarounds, Particle and surface supersampling, Timesteps and CFL (Adaptive Timestep Sensitivity). Continuing with the stat files, learn how to debug and benchmark the simulation speed for optimum performance.
 
Fountain splash pass
In this chapter you will create a secondary element for the splash pass. Decipher the difference between particle and particle-liquid NOP. And watch a detailed description of the Emission Criteria settings in the Splash-Emit NOP.
 
Naiad Ocean Toolkit
The "NOT" or "Naiad Ocean Toolkit" will be discussed at length in this part of the video labeling settings description and examples. Learn how to import meshes back in Maya through the Naiad Buddy and adjusting NOT particle shapes.
 
Multi Chapter Featured Project: Hero Boat Wake
Part1: Water tank setup
? Overview on the pipeline process of a boat wake
? Geometry export with Naiad Buddy.
? Setting up a waves tank graph: step-by-step description of the graph.
? How to limit the reflections form the tank ( boundary layer )
 
Part2: Extending ocean to horizon
? Setting up the ocean extention plane with NOT
? How to tweak velocities in collision objects
? Adding ocean waves to the original sim
? Combining the results
 
Part3: Foam pass
? How to setup a Foam pass of kinematic particles ( passive ) sliding on the surface of the water.
 
Part4: Splash pass 
? Setup for a splash pass with balisting and fully dynamic particles. 
? Herd the particles from the main water sim to generate a light emission criteria cache which we then use to spawn a fully dynamic splash system.  
 
Part5: Wet pass
? Setup for a wet pass. 
 
About Diego Trazzi
Diego Trazzi is an accomplished effects professional, who has been in the industry for more than 10 years. His earlier years involve TD generalist work and motion capture before he turned into a savvy in special effects, extensively on fluid simulation.
His recent award was the Best single visual effect of the year in VES award 2009 for the highly talked-about “Neytiri drinking shot” in Avatar, which was predominantly Trazzi’s contribution for fluid simulations. He was also one of the very few people who helped developing Exotic Matter’s “Naiad” since alpha version.
 
Started his career from Italy then reached to several continents, Trazzi has completed a long list of remarkable work on major film titles such as X-men : First Class, Avatar, The A-Team, Harry Potter and so on. As a result, he has acquired a broad range of technical knowledge and problem solving skills. At Siggraph 2010, Diego Trazzi gave a presentation on liquid simulation in Avatar, which was one of the highlights of the sessions.
