TYPE: SOP
TITLE: Ray SOP

Ray projects one surface onto another.

Parameters:
    Group                      - Group of primitives or points to project.
    Entity                     - Project points or primitives.
    Collision Group            - Group of primitives to project on.
    Method - 
        Project Rays           - Points are projected along their normals
                                 until intersecting with collision geometry.
        Minimum Distance       - Points are placed on the closest point on
                                 the collision geometry. This method does
                                 not use point normals. Use it to shrinkwrap
                                 or project one primitive onto another.
    Transform Points           - Move the intersected geometry.
    Intersect Farthest Surface - Ray source is projected to farthest 
                                 collision surface instead of the closest.
    Point Intersection  Normal - Ray point normals gets value of 
                                 collision normals at points of intersection.
    Point Intersection Distance - Ray point DIST attribute gets value of
                                 distance to collision source.
    Scale                      - When transforming points scale the     /scale
                                 intersection path.
    Lift                       - Offset surface in normal direction.     /lift
    Sample                     - Number of rays sent per point.  If    /sample
                                 greater than 1, rays are randomly
                                 perturbed and averaged.
    Jitter Scale               - Controls perturbation of extra rays.  /jitter
    Seed                       - Seeds the random number generator.      /seed
    Create Point Group         - Point group of all successful intersections.
    Ray Hit Group              - Name of the point group.
