Calculates the intersection of rays.
Calculates the intersection of rays in the family ray_family with the surface of the mesh. The position and direction of the rays are given by the variables rays_position and rays_direction. The array rays_orig_face contains the local ID of the face from which the ray originates. This array is used in the IRayFaceIntersector.
In return, rays_face will contain for each ray the localId() of the intersected face or NULL_ITEM_LOCAL_ID if a ray does not intersect any face. The array rays_intersection returns the position of the intersection point and rays_distance the distance of the intersection point relative to the ray origin. The array user_values is filled in return by the IRayFaceIntersector.
In parallel, the rays in the family are exchanged between sub-domains so that a ray is in the same sub-domain as the owner of the intersected face. If a ray does not intersect any face, it remains in this sub-domain.

Calculates the intersection.
In return, the array faces_local_id contains the local ID of the intersected face for each segment. If a segment does not intersect any face, the corresponding local_id is NULL_ITEM_LOCAL_ID.

Sets the intersection callback.
This allows the caller to specify its method for calculating the intersection of a ray with a face. If this method is not called, a default intersector is used.
