Abstract:
The present disclosure describes a system of fast intersection between secondary rays and geometric objects for a global illumination ray tracing. A hardware graphics pipeline of GPU is used as a means for carrying out the intersection between secondary rays and scene geometry in large groups of rays, gaining high speed and lowering computational complexity. The resulting power consumption is reduced.

Claim (Index 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:\n A discrete GPU having a hardware graphics pipeline, A CPU, memories serving said GPU and CPU, a geometric data base of the scene, a render target memory;\n wherein in runtime,\n (I) graphics processor shoots first projection of rays at a cluster of existing hit points for acquiring a depth map of the existing hit points; \n (II) graphics processor shoots at least one second projection of rays, through said cluster of existing hit points, utilizing the acquired depth map for creating secondary rays; \n (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; \n (IV) existing hit points are matched with points of intersections of related secondary rays and the render target; and \n (V) the identity of objects represented at the points of intersection of secondary rays with the render target are located.
