Houdini 20.0 Nodes VOP nodes

Fast Shadow VOP node

Sends a ray from the position P along the direction specified by the direction D.

This operator sends a ray from the position P along the direction specified by the direction D. The length of the D vector represents the farthest distance considered when checking for occlusion.

The operator returns 1 if there are no occluding objects found, and 0 0 if the ray hit any object in between.

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.
