本教程是由cmiVFX机构出品的Houdini VEX Volume教学1，时长：2小时37分，教程使用软件：Houdini，大小：633M，格式：MP4视频，作者：david gary。

应广大客户要求，CMIVFX发布了一套新的关于VEX与VOP教学的前两部，VEX是让HOUDINI有别于其他软件的特色，它最开始是被设计为一种强大的渲染语言，它能够被扩展开让用户创建自定义的Operators，像SOPS,POPS,CHOPS。VEX编程可应用的范围相当广阔，使用它你能够重建基本上半数的nodSop,并且或许是最容易被掌握的方式。使用它你能够创建surface operators，建模工具，变形器。

Houdini 是一个特效方面非常强大的软件。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不光只适用于视觉特效的制作，随着HOUDINI适用于各种平台，并且出现了很多的HOUDINI培训教学，HOUDINI开始进入了动态图像设计领域。因为其自身的流程化特性，加上其强大的动力学系统，让HOUDINI在数据可视化方面占有一席重要的地位，让图形设计师能够通过它表达自己的观点。

cmiVFX Houdini VEX Vol.1

Upon general request, CmiVFX is proud announce its two first volumes of new series of Houdini videos about VEX and VOPs. VEX is one of these things that makes Houdini really unique. Initially designed to be a powerful shading language, its paradigm has been extended to enable users to create new custom operators (like new SOPs, POPs, CHOPs). With the Houdini visual programming philosophy, VEX comes as a new dedicated context: VOPS where the data flow of your program is represented by custom nodes that wrap mathematical functions. VEX programming is so immense of a field that you could recreate almost half of the nodes of Houdini in all context combined ! So we had to start somewhere. These first two videos are an introduction to VEX/VOPs in the SOP context, maybe the easiest one to master: this means you’ll learn how to create new surface rr-sc.com operators, new modeling tools, new deformers with VEX/VOPs. It is at the same time an introduction to VEX concepts that are shared among all the various contexts, that we will reuse in our videos about rendering and shader development, or in videos about particle animation .Seashells, global deformers, water ripples… while being a language reference, these videos are intended to be a great cookbook for useful mathematical formulas
