Volume Gradient

[darioOrtisi]

Hi all. I will ask to everybody helps me on this: https://www.youtube.com/watch?v=unIuhd3Hff4

I wil llike to transpose this to bifrost. What i don't understand is how to get gradient vector, so i can add cross product.

I saw there is gradient normal,. How to get this info out?

I know there is a analyze_volume that has gradient_. But i'm still there. without success.

Thanks

I would go with fields and get the gradient field from fields.
You can also use the analyzed volume but then you need to sample that data with the sample volume gradient

Thank you @sepu6 

I did this today. But(hilarious) i don't know what i did. I'm using cross product i understand but why some aspect run, i don't know.

THat's the scene in case you have time to explain to me what i did.
