What is Enhanced Photon Mapping Techniques about?
This document describes improvements made to the photon mapping algorithm and its implementation in an extended photon mapping integrator. Key improvements include shooting photons in proportion to light power to reduce weight variation, using an outgoing radiance photon map to speed up final gathering, and importance sampling final gathering rays based on photon distributions. These changes result in an implementation that is over seven times faster and produces higher quality images than the original phot
