《Realflow对象破坏技巧教程》CMIVFX Realflow Destruction Tactics Vol 01

本教程是由CMIVFX机构出品的Realflow对象破坏技巧教程人人素材，教程使用软件：Realflow，时长：6小时，作者：Hashem Alshaer，官方发布时间：2012年3月8日。

在现实生活中，当我们要破坏某个东西的时候，是举起一把锤子，然后砸向你需要破坏的东西。但在CG视觉特效中，这是行不通的，我们需要使用很多的工具来制作合适的破坏场景，从而能瞒过人眼。自从黑客帝国-矩阵以后，我们取得了很多的进展。现在我们还会觉得1999年制作的电影真实吗？现在公众已经能够在高分辨率的显示器上看出所有人为的东西。在接下来的教学中，我们将使用你最喜欢的工具，设计出一个最好的工作流程呢个。在这套教学系列中我们将使用REALFLOW作为主工具。但我们也会告诉大家如何在HOUDINI,MAYA,3DS MAX中做同样的工作的。

Today, cmiVFX will begin a trip into the deepest fathoms of visual effects knowledge. The infinite detail of a destruction scene, needs to be under control at all times. When you destroy something in real life, you grab a sledge hammer and you smash what you want to break. In the world of visual effects, a sledge hammer won't do the trick. It takes many tools to do a proper destruction scene that can be believable to the human eye. We have come a far way since movies like the MATRIX, which have set the bar for visual effects trickery. Can you believe that movie released back in 1999? The scrutiny of the public eye has honed in on all the flaws that higher definition monitors allow us to view. So to simply say we can teach you all of this in just rr-sc.com 3 hours, well that's a foregone conclusion. We can however, create a workflow pipeline that uses your favorite tools, and let you decide the best path for YOU! In this series, we will use Realflow as the main application for all of the destruction, but we will show you how to prepare materials similarly in Houdini, Maya and 3DS Max. Why? You might be asking your selves right now. The answer is, we simply do not want to leave any stones unturned. This video series will be for ANYONE. It doesn't matter what apps your used to, because we are going to cover them all! This means that these videos are much longer than normal. You will need to drink lots of your favorite energy drink, and make sure you don't have any distractions. If you have children, now might be the time to put them up for adoption.

Reaflow Destrction Tactics Volume 01
In this video we will start from scratch. The learning structure used in these videos, gears all users up to be able to follow its contents from start to beginning. This is one of the few videos made that allow a novice, experienced TD or mid level 3D artist the ability to learn on the same level.

To make a long story short, this very first video in the series is extremely complete and packed with information. We did our best to find someone in this Universe that could handle the task of producing this vast array of knowledge. That in itself is a pure miracle. We do not give awards out for VFX training videos, but if they did… we would win for "Most amount of content in a single video". That being said, we hope that you enjoy your new found solitude and wish you the best of luck.  (After watching this video, you won't need luck, you will need clean plates to destroy!)

Short Description
This video is the first in a series to teach EVERYONE how to do proper multi-level, multi-layered, destruction using Realflow and a plethora of other 3D CG Animation Packages. We will show you how to do things in Houdini, Maya and 3DS Max so that you can jump between all of them depending on where you work. Now you have no excuse not to be a VFX MASTER.

Chapter Descriptions

Introduction
In this very first chapter we will try to quickly showcase NextLimit's Realflow 2012 special environment and its new features, and to discuss some critical factors and rules to follow for an efficient VFX pipeline (Scale, Cache and SD Files).

Anatomy Of A Body
The process of destructing objects needs more than one or two steps to get done so here we will talk about these steps, from fracturing objects, connecting them together, and how to handle several thousands of rigid bodies in one scene.

Fracturing
In details, we will describe the process of preparing our scene and objects for destruction, using different 3D programs  Houdini, Maya, and 3DS Max) to fracture and correctly divide our meshes in order to get them ready for impacts.
We will learn how to build special tools and different methods to fracture our object
1- Fracture tool in Realflow 2012.
2- Fracturing objects using "Ready Made" drawn poly mesh (Max, Maya, and Houdini).
3- Fracturing objects using volume point cloud and Voronoi fracture tool(Houdini and Maya).
4- Fracturing objects (procedurally) using modified Voronoi pattern and impact points (Houdini).
5- Fracturing objects using - image based fracturing - method, by using an image, pattern, or hand drawing lines (Houdini, Max).

Base Ball Through Glass
(Rigid Body Collision, MultiBody, MultiJoints)
In this chapter we will get the results of our first infamous ( ball, bullet ) impact through glass effect using a variety of material types. (normal glass, glued glass, car glass)

Fallen Hard Boiled Egg
( rigid body-soft body interaction through multiJoints and MultiBody )
Here we will study a very special case of multi layered ( soft, rigid bodies ) objects behavior and rules, where we will observe and create a boiled egg impacting with the ground.

Object Is Animated To ‘Paint’ The Path Of Destruction
(Asphalt behavior, rigid body-soft body interaction through MultiJoints and MultiBody )
It's always interesting to know how to simulate ground destruction and asphalt behavior using a multi layered ground surface. In this chapter we will build,step by step, the underground (soft body) and the ground (rigid body) and connect them using multi joints nodes, to get the best interaction through this multi layered object.

Bullet Collision Deformation
(Elastic-rigid-soft body interactions)
In this section, we will try to simulate the slow motion impact of a bullet against a solid metal wall using soft and rigid body interaction, where we will try to mimic the deformation and metal-melting (Due impact temperature increase) of the metal bullet and the wall.

WhatNext?
Take a quick look at RealFlow Destruction Tactics II (Bridge Destruction, Massive Destruction Scenes). We will talk about the second course of this series, which deals with massive destruction scenes rules, BRIDGE DESTRUCTION SCENES...
