stereoscopic imagery

Hi all, I saw Avatar in 3d last week, wow - total immersion! Rendering stereo images with RS is easy, but viewing it comfortably is another matter. You can view the attached image by crossing your eyes until the two images merge and 'click', but it requires some practice and it can cause

Hi Mark,   If I remember correctly, the 3D setup we had at BYU in the animation/design department was with one projector horizontal polarization, and the other vertical polarization (obviously the same with the glasses). Playback was off of one of the supercomputers, that only a few people had

I think that the 3D displays are coming rather rapidly. In the mean time, however, I think that shutter glasses might be the most realistic approach. A few years back, one could get graphics cards with a separate v-sync output that could toggle LCD shutters at each frame. I was thinking about

To see 3D images side by side this is what you need http://www.pokescope.com/ The best technology in 3D projection is not rotating polarization but Dolby 3D. Each eyes only sees part of each color. Like that there is no loss of brightness. 3D in motion is really difficult. You cannot make

With the shutter glasses approach you can use regular frame rates. Dolby 3D and RealD 3D, use higher refresh rates showing the same image for each eye several (three) times before moving on to the next actual frame, but if you aren't too fussy about it, a 60 Hz refresh rate, just showing each

An old camera for film set-up was two lenses taking half each of the same film frame. This gets over the need to synch the takes. The projector had a similar mirror (actually a beam splitter type lens I think) and projected through the colour/polarising filter for a glasses viewing solution. In

Saw an interesting one, an animated gif on loop showing old stereo prints (for those old hand held stereoscopes) one after the other with a fairly decent delay. The eye was totally tricked and saw a 3D view. Even the extremes of shift were just about there. My guess is that these extremes

behaviour is a natural one for the eye Certainly. In fact one cue to depth perception for the brain is the degree the eyes have turned to bear on a point in space. The old stereo cameras had no such mechanism so far as I know. The two lenses simply pointed straight ahead. It is for this

Hi Mark, I saw Avatar too in Imax format. But I must say this stereo projection gave me a headache too. Not just me, but my son and daughter were complaining too. I think I had problems with focusing on the subtitles and the image at the same time. Furthermore, because of the 3D effect, you get
