LCD glasses normally,
Polaroids, the screen is black!
OK, solved that mystery. As I _did_ use this monitor with the Asus glasses before, and it worked normally, what could it be? The clue: I have 2 Asus LCD shutter glasses. This time I took the very old ones (1995 or so?), and those do not work with this LCD (but work with a CRT of course). Because in case of the LCD, when light comes through, that light has one unique polarisation. Those old glasses, manufactured _before_ LCDs were commonly available, have the polarisation 90 degrees rotated from the LCDs, so nothing comes out when eyes are horizontal and looking at a LCD monitor.
Took my newer (8 year old or so) Asus LCD shutter goggles, the ones I normally use, and all works OK. Turning those 90 degrees blacks out the LCD though... So it seems Asus changed the design when LCDs became available and rotated the polarisation plane
90 degrees to accommodate those (sure hope they do not make them random out of a piece of sheet ;-).The old ones are in a box marked; Asus VR 3D VR100G, those do not work with LCD. The new ones are in a white box without markings...., those came with the Asus VR7100 de Luxe graphics card I bought in in 2001 or so.
Now that is clear no?? LOL Anyways you need the right glasses, or keep your head tilted all the time, but hey, you could turn the LCD monitor vertical and the cameras too! hehe
On problem left: I need more frames per second. Now that is an adventure involving display, USB, driver, and webcams.
An interesting idea for a new product: TV blank out glasses. When you do NOT want to watch a movie in the living room that everybody else is watching, wear those old LCD glasses. The screen will be 100 % black.
OK Usenet patent, here you find it guys: PRIOR ART. Would not surprise me if somebody already thought of that before me. You can experiment with a LCD monitor and rotating Polaroid sunglasses too I think.
