I think you mean the Ray operator (aka the Ray Sop).

You can use it to project points from one piece of geometry onto  
another. If you toggle on the "Point Intersection Distance" parameter  
it will add a float[1] point attribute called dist (accessible through  
the $DIST local variable) to the output geometry which contains the  
intersection distance for each point.
