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

In this 4th episode I'm explaining variables and operations with VEX which is one of the essential concept of any programming language.

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 a variable?
00:03:44 Variable creation with VEX
00:09:43 Numerical operations with VEX
00:17:27 Numerical casting with VEX
00:23:03 String operations with VEX
00:25:03 String casting with VEX
00:33:45 Vector operations with VEX
00:53:37 Dot operator for vector with VEX
01:01:12 Next topic - Arrays

    Wish this was around when I started out ... really eases into concepts and practical applications. Cant wait til one about arrays pops up
  • @maurypb
    Thanks for doing this, very thorough. Appreciated!
  • @jonosvlog9913
    Thanks for the amazing video! Really good for Houdini Beginners!
  • @TunafishnCrackers
    Thank for these videos, I'm familiar with the concepts but these tutorials really helps to build up a solid foundation and understanding of some complex subjects. Thank you for taking the time to make these videos.
  • @stevensilcock
    Doh! I just got to this video in the series...Scene View split for spreadsheet...ignore my suggestion on the first video. :hand-purple-blue-peace:😀
  • @skrotov
    Thank you)) going to arrays =))
  • @zoharlevin83
    great tutorial! thanks for [utting it all toghter
  • @billlee9757
    thank you very much Mr. but I am confused about the vector multiply. v1 ＝ （1，2，3）； v2 ＝ （4，5，6）； why v1 * v2 ＝＝ (4,10,18)? I can't understand it neither dot or cross. I think the result should be 32for dot or (-3，6，-3)for cross. I am a beginner with vex,is there anything I missed? thank you very much again for these wonderful lessons. hope you have a good day.
