all hdr does is take light, or more accurately, color data from a set of exposures and uses a given algorithm to produce the photographed scene as the human eye, or a receptacle with the ability to perceive a greater dynamic range would have captured it.
this however, just takes geometric data and a light source and computes the distrubition of light against the given angeles on a pre-rendered background. it's pretty simple in theory, but the effects as displayed are pretty impressive to see because of the illusion of real light being cast.
a few minutes of doing this in photoshop to simulate effect (mine isn't near as good because i can't compute math for angles light attenuation, etc.)
