本视频教程是由cmiVFX机构出品的3D-Coat与Houdini树木植物场景制作视频教程，cmiVFX Speedtree Collections With 3D-Coat and Houdini，时长：4小时27分，大小：8 GB，格式：MP4高清视频，附工程源文件，教程使用软件：3D-Coat, Houdini，语言：英语。
3d-coat 这是由乌克兰开发的数字雕塑软件，我们可以先看看官方的介绍：3D -Coat是专为游戏美工设计的软件，它专注于游戏模型的细节设计，集三维模型实时纹理绘制和细节雕刻功能为一身，可以加速细节设计流程，在更短的时间内创造出更多的内容。只需导入一个低精度模型，3D-Coat便可为其自动创建UV，一次性绘制法线贴图、置换贴图、颜色贴图、透明贴图、高光贴图。最大材质输出支持4096*4096做到真正的无缝输出。
实际上，由于3D-Coat这款软件正在不断的更新，它官方的介绍已经有些落后了，目前最新的3D-Coat3.0Alpha系列版本不但可以进行前面说的细节雕刻和各种贴图绘制，还增加了拓扑功能，体积雕塑功能，硬件渲染功能等等，由于软件的更新速度实在太快，以至于我们目前还不能说3D-Coat最后会发展成为一款什么样的数字雕塑软件。
另外需要提到的是，软件的开发者在软件的信息中说他们是虔诚的基督徒，所以请用户不要将软件用于开发淫秽和色情的项目当中。由于软件是可以选择中文界面，所以我们可以很方便的阅读到这些有趣的信息。软件最重要的还是功能，各种功能直接关系到用户对软件的评价，功能强大，使用简单的软件始终是软件开发者和用户的追求。
Houdini Master（电影特效魔术师）是Side Effects Software的旗舰级产品，是创建高级视觉效果的终极工具，因为它的横跨公司的整个产品线的能力，Houdini Master为那些想让电脑动画更加精彩的艺术家们空前的能力和工作效率。许多电影特效都是由它完成：指环王中“甘道夫”放的那些“魔法礼花”，还有“水马”冲垮“戒灵”的场面，后天中的龙卷风等等，a52的汽车广告，反正只要是涉及DD公司制作的好莱坞一线大片，几乎都会有Houdini参与和应用。
Houdini 是一个特效方面非常强大的软件，主要面对的是电影工业的特效制作与合成。与其他如3DS Max/After Effects等三维动画、特效合成软件不同的是，Houdini是一个节点软件，节点的操作具有非常强的逻辑性，同时它也是一个动态的建模软件，通过一个个节点和命令将各种对象组合在一起，在应对含有非常多的视觉元素的影视特效合成时通过节点的操作更加容易管理成千上万的视觉元素，而其它通过层来操作视觉元素的特效合成软件如After Effects在面对成千上万个视觉元素时显然是不现实的。许多电影特效都是由它完成:指环王中“甘道夫”放的那些“魔法礼花”还有“水马”冲垮“戒灵”的场面……后天中的龙卷风的场面等等，a52的汽车广告.反正只要是涉及DD公司制作的好莱坞一线大片，几乎都会有Houdini参与和应用.
cmiVFX Speedtree Collections With 3D-Coat and Houdini
For the better part of a decade, creating intelligent clusters of realistic foliage presented many challenges and far less solutions. During this time, I have spent my efforts assisting many vendors application design and workflow development. By doing this, it allowed me the opportunity to work with some amazing people with very unique approaches to various post production systems. This video is a collection in its own of a trifecta of CG applications that can provide their own independent solutions for what we are now calling “Collections”. The term is derived from IDVC’s SpeedTree application which just won an Academy Award. Its been an honor working with this affiliate, and it has allowed many of my ideas to seep into this new found prize. This one leg of our software tripod is really the center of our show, but equally parted to help create the most efficient amount of lesson material in our allotted time slot. To kick off our video, we will start with one of the most brilliant apps on the market, which is soon to be a viable replacement for all sculpting apps, thanks to its support for OSX, Linux, and Windows respectively. Every app that I am showing in this video is designed to work on ALL OPERATING SYSTEMS for good reason. 3D-Coat is famous for its sculpting and retopology tools, allowing for highly detailed models that are super clean and light weight. It works very well, and we will show you how to sculpt, paint, retopo, and bake in such a way that you COULD create your entire scene in any of these apps, OR all of them just the same. After 3d-coat, SpeedTree is used to create our dynamic tree and foliage systems with the assembly of outside geometry and modified plant libraries as well as hand generated ones. Learn how to use dynamic and geometrical forces to help model details such as tree roots that cling to a cliff, or ivy leaves that creep up from the ground onto tree bark. We also cover methods of population which will work without custom tools for their world building kit. Now EVERYONE can populate and export directly from SpeedTree without further need of Python tools! In the end, we will show all the final assets and demonstrate how to set up a scene in Houdini. We do this in the latest version of Houdini so that you can see all the new changes to the shading system. All the final renders that aren’t shown in realtime are produced in Houdini for this project. But this video was set up so that you could use Maya, Max, C4D, Lightwave and more to assemble your final assets. This video is officially for everyone that would ever need to create a digital environment.
