Follow-up on this: volume colorization and SSAO prototype is now available in VTK + 3D Slicer and the results are very impressive. Quality is comparable to (and in some aspects better than) other “cinematic” medical image renderings and its computational cost is very low. See details in this topic:

The computation was also really slow and on some computers it did not work at all. Most of the medical examples that were showcased in Kitware blogs looked quite odd, too, they looked different but not really better than plain volume rendering. With the help of @pieper and @LucasGandel we implemented two improvements in VTK and 3D Slicer that dramatically improve clarity…
