 +====== Progressive Lightcuts for GPU ======

 +**Abstract**: Lightcuts [[http://www.cs.cornell.edu/~kb/projects/lightcuts/index.htm|Walter et al. 2005]] is an attractive rendering algorithm that efficiently handles complex lighting by adaptively approximating the illumination at a point using clusters of virtual point light (VPL) sources. Two of its limitations are the infinite amount of
 +memory required for variance convergence and the bias introduced by VPL contribution clamping. We present a consistent progressive Lightcuts variant, which converges to the correct solution with a bounded memory footprint. This is essential for high quality rendering, especially considering the tight memory budget on the GPU.
