[VEX for Algorithmic Design] E10 _ Volume 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 10th episode, I'm explaining the basics of Volume when used 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 a volume?
00:05:08 Visualize and modify scalar volume
00:18:00 Visualize and modify vector volume
00:27:17 Create volume from surface
00:35:05 Volume attributes 1 (position)
00:39:32 Volume attributes 2 (index and resolution)
00:47:45 Volume VEX functions 1 (volumesample)
01:02:55 Volume VEX functions 2 (volumesamplev)
01:14:56 Volume VEX functions 3 (volumeindextopos, volumepostoindex)
01:28:59 Volume debugging

Hi, maybe you should consider similar series with RBD ,Particles and Liquids because your teaching is straight forward and easy for a beginner to grasp. Thanks for all your free courses helps noobs like me a lot.

[@DMCvsKILLER]

Juni, i love your tuts man. Really really good!

[@DoHoan_FX_Supervisor]

Love it!! Really clearly. Approached stuffs with your new ways.

[@__SKYNET__]

Masterpiece! This information is not available anywhere on the internet to such a detail!

[@riwata3853]

個人的に神回でした！

[@massimobaita7178]

Thank You very much, Junichiro!

[@simonvandenbroek6384]

You are a valuable gem on the web. Keep doing what you do.

[@tomashaverlik]

Simply the best channel with best tuts. Thank you Juni!

[@dissonantprotean5495]

amazing stuff. Thank you for sharing. Just eating this up. I put off watchng your videos for a while but it has been perfect now that I want to get serious about learning sims and algorithmic design

[@quackcharge]

one day i'll order you a nice cake and some flowers :)

[@StephaneSOUBIRAN]

Thank you, very useful !

[@00000o0o0]

You are such a hero. Thank you so much

[@AnsonSavage]

Your stuff is great!! Thanks so much:)

[@mukundkm7129]

We love you maahn!

[@peterpejanovic2652]

Nice!!! Super tutorials and also many thänx for the file scenes too!!! Makes it a lot easier to learn Houdini. You should name yourself Houdini too:)

[@AncienRegimeStudios]

Once again an excellent tutorial but I did have two problems at the start. As Junichiro has said below, at the beginning I had to 1. in Volume node, go from Dimensions Tab to Properties Tab and then increase Display Density from 1 to 2. 2. in Volume Visualization Node in the Smoke Tab, you have a Diffuse Field not just for the Density Ramp but also for the Diffuse Ramp. The video shows him putting "density" into the Diffuse Field box but I also had to put "density" into the Density Field box too. Then it worked perfectly as per the video. I was getting worried there thinking it was my Radeon VII and my OpenCL settings or something like that.

[@solo-moon]

thank you this helped

[@sumonecalledalex]

Thanks Juni

[@arsensuleymanov7935]

Thanks!

[@jamaljamalwaziat1002]

What is the relationship between them and pcopen in houdini

[@spyrospyliolekkai4587]

Hallo, Does anyone know why I can not visualize the volumes but I get an empty binding box instead? I have HDR rendering on and wrote the name of the volume in the visualize node. Can it be a graphic card problem??

[@user-yt1hb6kh1k]

Same issue. I just wrote 'velocity.*' in 'Density Field' and it showed up, but i still got strange colour results when adding Volume Wrangle new velocity values.

[@user-yt1hb6kh1k]

The problem was in volume size. If you guys have strange colour results just icrease the volume size.

[@lanceymiku]

Have you solved the problem?

[@spyrospyliolekkai4587]

@@lanceymiku Yeah, I wrote density in the density field as well, and it worked.
