I have a mesh grid. Each point has an attribute with a different value. For each point, I'd like to compute the "gradient" vector for this attribute: a vector pointing in the direction of the largest difference in attribute value between the given point and its surroundings. I can do it with vex code, but is there maybe a SOP that already does this automatically?

Hey element33,

yes, the polyframe node can do it. Set its style to attribute gradient.
Your attribute must be from type vector for some reason.
So you have to convert your float attribute to a vector first.

Nice, thanks.

You can also use Measure SOP
