Hi, folks - this thing bugs me a bit

Modifying/advecting a simplex noise by velocity from curl noise.

This is from a SideFX talk : https://vimeo.com/album/5422586/video/267864823 [vimeo.com] - starts at 10:37

so basically we start from here:

and we end up here :

The whole shabang is in theory straight forward, but I'm struggling with this velocity advect inside the point VOP

I have prepared the file with the initial velocity if it's of any use.

I can't seem to understand how a vel attribute can be sampled, (get attrib “vel” array?) it is obviously some for loop sampling.

here is the VOP from the video, of course this part is skipped:
