the philipps WOW 3d display is fully supported from Vizard, its plug and play. it looks 'stereo' out of a certain perspective, as it sends left/right eye info into different directions, so both your eyes get a different image.
3D displays which don't require 3D glasses (so called autostereoscopic displays) always have the drawback that they only work out of a certain perspective. when you move your head, the stereo will fall apart (both eyes see the same) or you see inverted stereo (left eye sees what right eye is supposed to see and vice versa).
next to that, such displays tend to have a certain amount of 'crosstalk' which means that even under optimal conditions (i.e. your eyes at the 'ideal' position) your left eye get's some percentage of the right eye's image and vice versa. this makes it 'harder' to look into such displays for a long time and causes headache after a few hours if you really have to work on such a display.
there are some autostereoscopic displays which are optimized for very low cross talk (i.e. are better for working in front of them for a couple hours) but those have stronger artifacts when your eyes move out of the sweet spot (i.e. black lines or circles).
such 'low crosstalk' displays can be combined with eye tracking and electronic or mechanic pixel shift technologies, and then the sweet spot 'follows' the eye and you will have indeed 'real' stereo perception for ONE person in front of such an eye tracked display in a certain area. Formerly ACD Kern (now purchased by Richardson Electronics) offers such a high end display for some $ 50,000.
so bottom line, autostereoscopic displays are certainly a very interesting technology (for example for marketing displays, shows, etc.) but come with a bunch of trade-offs which make them different from systems with shutter glasses or HMDs which provide 'real' tracked and zero-crosstalk stereo if used correctly.
hope that helps,
