Abstract
Massive point data sets representing meticulous details of various heritage sites and statues are now becoming available due to recent advances in multi-view stereo techniques. Photorealistic rendering of such point sets has not yet, however, matched their polygonal counterparts with respect to the interactivity of applications as well as the quality of light simulations. In these papers, we present a framework global illumination for point based models that involve the design of new data structures and GPU based implementations that enable us to further the state of the art by demonstrating diffuse and specular reflections, refractions, shadows and caustic effects on massive, complex point models at interactive frame rates.
