It seems the military-cinematic complex has discontinued their drive for 3D, with close to zero movies being showed in 3D, at least in my city, in recent months, whereas for many years they were, to use the textbook words, "ubiquitous", a "plethora" of 3D movies! [1] Now, even sure bets like "Star Wars: Rise of Skywalker" was only shown in 3D for a very short while, then only in 2D, and the current "Sonic the Hedgehog" doesn't even seem to be available in 3D to begin with... [2] Unthinkable, just one year ago! I have to take it back from them, somehow. (Heh, I suppose this is the kind of story one shouldn't tell, but I did LSD once and Emacs in a Linux VT with the projector and font lock, and psitrance from the speakers, and the beauty was just breathtaking, it was more than 3D, the text floated in the air and glowed and bussed with the music...) Anyway in an attempt to make sense of the 3D technology available, I wrote this [last] on IRC. I was thinking about the anaglyph approach, because one can specify the colors in a Linux VT with great refinement (0-255 for each of RGB, i.e. your everyday hex computer color code, e.g. #636e1a for army green), shouldn't it then just come down to learning just what red/cyan or green/magenta colors it should be, for your specific anaglyph product? Especially since Infitec seems to have improved the anaglyph approach to a large degree, if one believes what I write below... re: 3D cinema technology/methods: 1) ancient-school side-by-side/cross-eye stereoscope, 2) old-school anaglyph glasses (red/cyan or green/magenta lenses, anyway poor 3D so why bother), 3) active glasses which blocks left/right upon receiving a periodic signal from the 3D gear (I think this is what IMAX does), 4) polarized glasses (let thru according to the direction of the light, i.e. the light intended for the left eye is perpendicular to the light intended for the right eye, also requires special gear - I think this is what I have at my local cinemas, or _had_ before they all dropped 3D that is...), and 5) Infitec glasses which is an upgrade of the anaglyph idea but uses a more advanced/better RGB scheme. the Blu-ray 3D version of "Battle Angel Alita" that I found shows two side-by-side frames, so what does that mean? I get a stereoscope and its 3D? one can play it in one frame with mplayer with -vo gl:stereo=1 and the result is something that might look like poor 3D with anaglyph glasses, only I don't have any so can't try... I have two polaroids and one pair from IMAX, but as expected, they won't help without the special treatment...
