آموزش شبیه سازی مایعات ، آتش و دود CGWorkshops - Fluids FX using Houdini 13

 

COURSE OVERVIEW Spencer Lueders returns with his content packed Houdini course. This CGWorkshop will take you to the next level using Houdini to simulate fluids, fire and smoke and will teach you the secondary elements required to produce high quality, dynamic simulations. Starting with the basics of voxels you will learn about smoke solvers, micro solvers and the Pyro Solver. You will then move on to gain a firm understanding of the Houdini FLIP Solver, particle manipulation and heuristics while working on your own simulation projects. This course will fill quickly as it is the perfect next-step for the many students who have worked with Spencer on any of his previous, highly successful CGWorkshops Houdini's Apprentice education edition software is available as a free download, and is all you will need to take this workshop. WEEK BY WEEK OUTLINE WEEK 1 - VOXEL SOUNDS LIKE A CITY IN EUROPE - THE ANATOMY OF A VOXEL In the first week we will be covering the introductory concepts of volumes and explore ways to create and modify volume data. The goal by the end of the first week is for you to be comfortable with what a volume is and what its properties are as we will go straight into more complicated workflows and concepts throughout the following weeks. We will cover: What a voxel is Properties of a Voxel Modifing Voxels Using Noise WEEK 2 - WHERE THEREandrsquo;S SMOKEanduml; THEREandrsquo;Sandhellip; - SMOKE SOLVER AND MICROSOLVERS Letandrsquo;s begin with some awesome! In week two, we will cover the smoke solver and how volume fields are used to create elaborate smoke simulations. We will begin to cover methods to increase control of our smoke simulations using Houdiniandrsquo;s andlsquo;microsolversandrsquo;. Functionality Of Volume Solvers Using Microsolvers to increase control WEEK 3 - FIRE! - THE PYRO SOLVER AND SOP SOLVER The Pyro Solver is essentially the Smoke Solver on steroids. This week you will learn to navigate the complexities of the Pyro Solver in order to fully maximize its capabilities. We will also take a look at the Sop Solver to modify attributes in order to dynamically change the location and behavior of our simulation. Understanding the fundamentals of the andlsquo;pyroandrsquo; model Shaping and Controlling simulations Using SOP Solver to Dynamically change emission WEEK 4 - IS IT ME OR ARE PARTICLES STILL LAZY? - USING VOXEL FIELDS TO MANIPULATE PARTICLES We can use the volume data created from fluid simulations to drive the behavior of just about any other geometry, such as particles. In week three we will take a look at using Volume Fields to affect particles. This week will segway into the following weeks' class of FLIP fluids. Advection using Volumes Houdini 13 Particles in Dynamics Context (DOPS) Analyzing Volume Data to Build Elements WEEK 5 - STUFF WHICH PERTAINS TO EVERYDAY LIFE - FLIP FLUIDS In week five we will take a look at Houdiniandrsquo;s FLIP particle fluid solver which is useful for creating...FLUIDS! Particle Fluids are used to generate splashes, sand, and oil to name a few. We will explore are the fundamentals of FLIP, various ways to control the properties, emission before we build custom forces to get the most out of our simulation. Particle Fluid fundamentals Controlling Fluids with dynamic attributes WEEK 6 - MORE FROTH ALWAYS SELLS A SHOT - GENERATING SECONDARY ELEMENTS When creating a water effect, typically it will require more than just a pretty surface to sell the shot. Week six covers effective methods for creating various secondary elements, such as foam, mist, and spray which get driven off of the base fluid simulation. Mastering these will help you achieve another level of complexity and realism to add to your simulations. Using Sim Data to generate Foam, Spray and Mist Creating Heuristics to modify behavior WEEK 7 - YOU CAN TALK THE TALK BUT WHAT ABOUT WALKING - SIMULATION WORKFLOWS As simulations can often times take hours and even days to complete, this week will explore methods for adjusting your sims efficiently so you can spend more time executing and delivering. To do this we will look at how to break down an effect into smaller components to allow for great flexibility and control. Methods to Iterate Simulations Efficiently Break down effect into small elements to gain control WEEK 8 - CGI ALWAYS LOOKS PLASTIC - RENDERING FIRE AND FLUIDS In the final week we will bring some of the various elements we have created together over the previous weeks and render them. We will also take a look at some advanced methods for generating volumes to render and ways to get the most detail efficiently. Methods for Rendering Fire, Water, and Smoke Elements using Mantra Generating Volumes from points WHAT YOU'LL NEED SOFTWARE NEEDED Houdini's Apprentice education edition software is available as a free download, and is all you will need to take this workshop. MINIMUM SKILLS This course is designed for the intermediate to advanced Houdini users. Students will need to have a foundation knowledge of Houdini, the UI and the general functionality of the application such as the node based workflow. Students who have completed Spencer's introduction course are ideally suited to this course. This course is designed on a technical foundation a good understanding of general 3D concepts is also essential.
