This operator sends a ray from the position P along the direction specified by the direction D, and returns the total amount of occlusion of shaded surfaces between the point P and the point P+D.
The length of the D vector represents the farthest distance considered when checking for occlusion. Each occluding surface is evaluated and its opacity added to the total amount of occlusion.
If the position (P) input is not connected, the global variable by the same name will be used instead. In the Shadow context, you will normally connect the global “Ps” variable to the “P” input, and the global “L” variable to the “dir” input.
