In Renderman Advanced they explain how to use system co-ordinate blockers. In filmmaking the lighting guys will often use boards to block off light.
This is very simple.
1. Under 3delight menu, Add Coordinate system.
2. put the name eg ‘delightCoordinateSystemShape1’ into the ‘blockercoords’ section of the
uberlight shader
3. Move co-ordinate system into place. Adjust blocker settings in uberlight.

    Well in my last production we were using blocker with lights and they were physical entities means you can visually see them in the viewports and adjust them.they were more or less like gradients but 3 dimensional with visual control of various falloffs .
    So, can you upload any script which creates similar kind functionality.
