Hi everyone, I am dabbling with volumes recently and I wish to know how can I have a fall-off of volume, gradiently? (see image attached).

I have zero to minimal knowledge of volume vop. Forum Users talk about volume sample and volume gradient when I search on forums regarding this issue.



**Additional Info– Better still if I can control, say, point A is densest and point B is thinnest.**



Thank you in advance.

Something like this?

Wow, this is it. It's very nice. Thank you! Really appreciate it.

Super cool ! this exactly what I was looking for ! thanks thanks thanks !

Hi there,
i am completely new to Houdini, sorry for that.
How would i create volumetric gradient, that is more dense at the bottom and density will be less at the top?
A volumetric vertical gradient i mean.
Many thanxs for help

Inside a volumewrangle you can just do:

Inside a volumewrangle you can just do:

@density = 1 - relbbox(@P).y;

thanks! and how this can be achieved along all three axes x,y,z?

Without testing, probably like:
