Real time ray tracing of point-based models

Mirroring the development of rendering algorithms for polygonal models, z-buffer style rendering for point-based models has given way recently to more advanced methods. A fast raycasting based approach [Wald and Seidel 2005] shows shadows, but does not demonstrate reflective effects. The more general raytracing approach [Linsen et al. 2007] is substantially slower.
