Stores the current ray to use for picking.
This element stores the current ray to use for picking. It contains the world space ray information in terms of an SbViewVolume. The projection point and view direction of the volume represent the ray itself. The width (which equals the height) represents the diameter of the picking circle in the near plane. The near and far planes represent the distances to the near and far planes between which valid intersections must lie.
