Fixing and playing around with things while I am trying to grasp the concept of photon mapping and the k-d tree data structure. I will try to get a working implementation by the end of next week since I have to hand in the fourth progress report.

Unfortunately, he has removed his photo-scanned leaves asset which do contain the geometry for the leaves and all the associated maps.
