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)

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.

-
You are a valuable gem on the web. Keep doing what you do.
-
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
-
Love it!! Really clearly. Approached stuffs with your new ways.
-
Thank You very much, Junichiro!
-
one day i'll order you a nice cake and some flowers :)

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.

Thank you, very useful !
-
Thanks Juni

Thanks!

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??

What is the relationship between them and pcopen in houdini
