[VEX for Algorithmic Design] E23 _ SDF Basics

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 23rd episode, I'm explaining the basics of SDF to show how you can deal with it together with VEX coding with several examples.
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 SDF?
00:06:08 Check SDF Values with Points
00:23:38 Check SDF Gradient with Points
00:27:23 Visualize SDF Value with Fog Volume
00:37:19 Basic SDF Modification with VEX
00:43:48 Animated SDF Modification
00:47:11 SDF Modification with Gradient
01:03:21 Basic Collision with SDF
01:11:46 Animated Collision with SDF
01:21:16 Basic Vector Animation with SDF Gradient
01:36:50 Extended Vector Field from SDF

Thank You very much, Junichiro!

[@Handcraftedcc]

This is fantastic. So many possibilities on what this can be used for!

[@maratmurtuzaliev4745]

Great stuff! Learned a lot! By the way, there is a function opinputpath(".", 0) to replace "../" + opinput(".", 0)

[@sinarhp]

Thanks very much for these great tutorials

[@AnsonSavage]

These are so helpful, thank you so much!

[@HAWii]

Thanks for this Great videos

[@marvelouswalrus949]

I am learning a lot from you. Thank you so much!

[@neill162]

Best instructor....thank you for the lesson

[@paolorava7912]

amazing! thank you!

[@danielkrajnik3817]

might be probably also worth mentioning that SDFs were huge in shaders and early graphics. In fact, CVEX was originally a shader language for mantra and it borrows a lot from this space.

Thanks for the videos, and I have a question, why my volumevisualization can't work? I have downloaded your file on Github, but still couldn't see anything , I am using Non-Commercial Edition, 18.5.462, is that matter? Hope for your reply!

Version 18.0 can not create point in Volume Wrangle...
