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。

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 nodSOP context, maybe the easiest one to master: this means you'll learn how to create new surface 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.

Seashells
Discover what is behind the algorithmic beauty of seashells, how nature is doing math, producing out of the same mathematical model an immense diversity of beautiful seashell silhouettes. Water Ripples: Learn how to simulate water ripples due to raindrops collision on the surface of a lake. Connect your VEX operator to a particle system and let it rain!

Multiple Inputs: In the same spirit as Renderman's DSO ( dynamic shared object), learn how to use several inputs in a VEX SOP, so that you can have helper geometries. The possibilities are endless, and you can now see Houdini's SOPs and CHOPs as an abstract extension of VEX data types and VEX functions.

VEX and VOP Workflow: Learn how you can create new VEX functions as well as new custom VOPs. This means that you're building operators whose purpose is to build operators... Add this to Digital Assets and Python meta-commands, and you get an unprecedented level of hierarchical customization. Learn how to integrate VEX and VOP in the same network.

Math
Matrices, polar coordinates, trigonometry, waves and later, noise octave summation, fourier transform, barycentric coordinates. Sound scary? Well it's not. Your new mathematician / personal trainer takes you by the hand in this world to spark your nostalgia about all that. You will be surprised to find all this math enjoyable again.

Rich as Book,Easy as a Video

This set of videos is the most comprehensive documentation you will find about VEX and VOPs. You will effortlessly progress through concrete examples, All the examples have been carefully chosen to leave no gaps in your education. The result is something which is as dense as a book, that you regularly come back to watch when your stuck on a project.
