How to get the min and max values of a volume?

Recommended Posts

I can iterate over every value in a volumevop SOP, but how can I compare one to another? Or is there a straighter way?

I have a workaroundish solution with attribfromvolume SOP: Getting the values from points, which I scattered in the volume.

I want to use these values for volumeramp SOP.

Can you use the volumemin() and volumemax() expression functions?

Oh man! Yep, Macha refers to the same function. I must have forgotten to check the expressions.

Anyway, I wish the documentation of volumes would be more detailed. I had to browse the forums a lot.

Thanks a bunch!

Edit: Or are volumes the same everywhere - not unique in Houdini?
