1. A computer based system for fast intersections between secondary rays and objects in ray tracing of a three dimensional scene, utilizing graphics pipeline, comprising:

  • at least one graphics processor with memory,at least one general purpose processors with memory,geometric data base of the scene,render target memory;

    wherein in runtime,(I) graphics processor shoots first projection of rays at a cluster of existing hit points for acquiring depth map of the existing hit points; and

    (II) graphics processor shoots second projection of rays through said cluster of existing hit points, utilizing the acquired depth map, for creating secondary rays; and

    (III) graphics processor renders with the secondary rays the three dimensional scene, or part thereof, storing the intersections of secondary rays with geometrical objects to a render target memory; and

    (IV) existing hit points are matched with points of intersections of related secondary rays and the render target; and

    (V) the identity of objects represented at the points of intersection of secondary rays with the render target are located.
