Depending on what you want to do, you could animate particles in flat plane
above the geometry and project them down. This is quick and dirty but may
look weird if you have a lot of height fluctuations since the particles will
move "faster" in those areas.

I used a trace SOP to create geometry from an image. The geometry has
fluctuations in height (waves in it). I want a particle to glide over the
surface of this geometry going up and down with the fluctuations. I've
attempted using the Creep SOP within the POP network with no luck. Any
suggestions for an alternative way to get the particle to stick to the
surface? I've heard of using primUV but don't know much about how that
works.
Thanks
