split tangent and normal velocity for SDF

Recommended Posts

Hi, 

The picture shows an object , create > test geo > add velocity > vdbFromPolygon with vel field > visualize velocity.

I wonder how to split velocity to tangent velocity and normal velocity. I guess we don't have a node to do it by one click, and need to work on volume vop/wrangle. 

If anyone knows how to do it, I will appreciate it, thanks!
