(L) [2014/01/26] [tby shiqiu1105] [Spatial date structure, kdtree or hash grid.] Wayback!Hi,
I have noticed that the original photon mapping algorithm uses a kdtree for storing all the photons, where as more recent implementation such as PPM or VCM uses a regular hash grid.
Is there a particular reason except for the ease of implementation? Any comparison?
Thanks.
