This operator sends a ray from the position P along the direction specified by the direction D, and returns the distance to the object intersected or a negative number if not object found. The position and normal of the intersected surface are returned in phit and nhit.

The length of the D vector represents the farthest distance considered when checking for intersections.

If the position (P) input is not connected, the global variable by the same name will be used instead.
