在本教学中你将学习使用HOUDINI的粒子来创建一些非常有趣的特效，你将会使用到DOPS,SOPS,POPS,VOPS,还有表达式来制作一些复杂的网络，从而实现这些特效。学习本教学，你需要了解HOUDINI的基础知识。
项目1：轨迹
本教学将告诉你如何从一个几何体创建一个轨迹特效，这个轨迹特效会缓慢的消失。这个教学将告诉你如何设置网络中的参数，让它们能够动态更新，还告诉了大家如何创建一个shader network，还有冬天照明系统。
项目2：粒子波
本教学将告诉大家如何使用SOPS,POPS，还有表达式来创建一个粒子波assets，教学完成的时候，你将会有一个完全由你控制的动态拼块，你能够控制高度，拼贴图案，还有拼块的旋转轴，缩放，拼块集的分辨率等等。
项目3：体积分裂
在这个深入的教学中，你将学习到如何使用SOPS,POPS,还有VOPS来创建体积烟雾轨迹，它们是由一个父级粒子控制，你将会学习到如何设置粒子网络从而让体积能够继承旋转，速度等属性。最终这个多功能的特效可被用于从火箭引擎到香烟烟雾等各种不同的特效中。
项目4：粒子目标
在本教学中你将学习到如何在HOUDINI中为粒子创建目标对象，这样你就能在不同的造型中融合粒子了，同时将所有的属性都保留在你的网络中。使用这个技巧你将能制作成群的昆虫到全息图等各种特效。
项目5 破裂
在本教学中你将学些到如何使用SOPS,表达式，还有DOPS来生成一个破裂操作。你将会看到如何制作一个网络从而生成破裂图案。接着它将被作为一个基础网络，来制作一整套的特效。你还会学习到如何重新使用你的网络来创建一些强大的ASSETS，从而创建各种各种东西，包括撕裂的纸张，破裂的水泥地，还有破碎的墙。
Houdini Technical Effects is your chance to learn how to create some extremely interesting effects within Houdini through the use of particles. You will use DOPS, SOPS, POPS, VOPS, and expressions to build the complex networks involved in the creation of these effects. These videos do assume a basic working knowledge of Houdini and are not meant for the complete beginner. If you are looking to take your Houdini knowledge to the next step, Houdini Tech Demo is for you. The techniques demonstrated in these videos will have you on your way to creating professional quality effects like those seen in blockbuster movies.
Project 1: Trail
These tutorials will show how to create a trail effect that is emitted from a piece of geometry, leaving a following trail that slowly fades out.
The tutorials cover all steps from beginning to end, showing you how to setup a network of parameters that update dynamically, how to create a shader network, and a dynamic lighting system.
Building upon those lessons, you are also shown how to create multiple trail effects that are either driven by other particles, or animated sets of points that belong to other geometry in the scene, allowing you endless possibilities.
Project 2: Particle Wave
This tutorial shows you how to create a Particle wave asset using SOPS, POPS and Expressions. When completed, you will have an animated tile set that is at your complete control. You will have the ability to control the Height, The tiling Patterns, The Rotation axis of the tiles, The scale, The Resolution of the tile set, and much more.
The end result is a powerful dynamic effect that you have complete control over and a great looking special effect that is only limited by your imagination.
Project 3: Volume Split
This in depth series will show you how to use SOPS, POPS, and VOPS to create volumetric smoke trails that are driven by a parent particle. You will learn how to set up a particle network that will allow the volume to inherit Rotation, Speed and Velocity. The end result is a versatile effect that can be used for everything from rocket engines, to cigarette smoke.
Project 4: Particle Goals
This series of tutorials will show you how to create Goal objects for particles inside Houdini. The video will take you step by step, and show you how to create dynamic goals for particles. So you can blend particles between shapes, all the while maintaining the attributes within your network. With this aspect in mind, you can effectively use this technique to create special effects ranging from swarms of insects to holograms.
Project 5: Fracture
In this series, you will learn how to generate a fraction operation using SOPS, Expressions, and DOPS. You will be shown how to build the network that will generate the fraction pattern. Afterwards it will be used as the base network for an entire set of effects. You will learn to reuse your networks to create a powerful asset that has the ability to create everything from shredding paper, to cracking concrete, to a shattering wall. The final result is a set of assets that came from a single fraction pattern. |
