This is a new series I've started explaining the basics of VEX for algorithmic design / procedural modeling which I'm using on daily basis.

In this 9th episode, I'm explaining what and how to use functions in VEX. You have already used some of the built-in functions but I'm explaining what exactly they are and how you can create your own function in this video.

I've also started a Patreon, it would be great if I could get your support to continue creating tutorial contents.

00:00:00 Intro / What is function?
00:00:56 Function types
00:04:09 Built-in functions overview
00:05:22 Void function
00:16:59 Return function
00:20:50 Exercise - nearpoint 1
00:31:36 Exercise - nearpoint 2
00:41:13 Exercise - intersect
00:54:54 User-defined void function
01:07:08 User-defined return function
01:18:17 Declare output parameter
01:22:32 Import preinstalled functions
01:34:04 Import user-defined functions

    I love this series, and in particular I love the way that Junichiro patiently explains each detail of the workings of VEX. He never assumes you know anything. VEX (and C or C++) are not easy to learn. This is as good a tutorial on them as you'll find anywhere.
  • @jahormaksimau1597
    Thank you!!!!! Will watch with pleasure.You are one of the best teacher and i love your videos.
  • @ArtStractStudio
    Dear Sensei Junichiro Horikawa, on my way to have a deeper understanding of Houdini, i watch step by step your lessons of this serie. They are very instructives and so patiently well explained. I would like to thank you for providing this high quality content to all of us for free, this helps alot. どうもありがとうございます

    As an additional note to this chapter, if one is using custom packages like I am which points to my external custom Houdini folder for example , creating a vex/include folder structure there also allows for the #include "spiral.h" notation . I'm aware that this might be out of the scope for this chapter. but i thought that it might be nice to know when users are organizing code this way as well. 💗Great series of video's Junichiro
  • @guitoma109
    Thanks Junichiro!!! Excelent hints at the end with the Import user-defined functions. See you in the next JuniFlix series E10.
  • @bomhaa

    堀川さんフーリエ変換は出来ますか？フーリエ変換で温泉の温度を周波数で微細に階層的に計測するとかは？（これフーリエ変換で出来るのかな？？・笑）
