 ## Extensive tutorial showing examples of usage of VEX scripting language inside SideFX Houdini
 <p align="right">by Juraj Tomori</p>

 ### How to use
 You can clone, or [directly download](https://github.com/jtomori/vex_tutorial/archive/master.zip) this repository.<br>
 It contains **examples.hipnc** and **vex/include/myLib.h** files which are full of various examples with explanations in comments.<br>
 Alternatively you can use this page for quick looking at the topics covered and some of the code that I include here as well. I am not including here all of the code since sometimes it might not make a lot of sense outside of Houdini.

 ### Topics
 * debugging, utputing text with printf()
 * hand editing of values in Geometry Spreadsheet, lock, delta lock
