Rendering of photo-realistic images at interactive frame rates is currently a n extensively researched area of computer graphics. Many of these approaches attempt to utilize the computation al power of modern graphics hardware for ray tracing based methods. When using path tracing algorithms the ray p aths are highly incoherent, hence we propose an efficient technique that minimizes the divergence in executionflow and ensures full utilization by intelligently regenerating the paths. We analyze the conditions under which our improvements provide the highest speedup, and demonstrate the performance of the overall system by re ndering interactive previews of global illumination solutions using (bidirectional) path tracing with progressive refinem ent.
