Raytracing PCD as implicit surface & Octree

36k points update: http://www.youtube.com/watch?v=hgr3zPSkvIs

Implicit surface: higher quality than disk render, more accurate surface silhouettes.
Raytracing and constructing implicit surface from pointcloud at interactive rates (video speed up)

3 clips:
1) No octree
2) In octree, radius 0.1: takes 60% time, very small speedup (compared to disk) since smooth surface requires more points. A denser model will benefit more from octree.
3) Radius 0.05: 36% time of 0.1 radius is a significant speedup. Smaller radius has less octree artifact due to less overlap, but less points mean it is statistically less stable as shown by the noise around ears.
(fastest version has noise mostly fixed in a later video)
