From: jvanripe_nyx10_cs_du_edu (Fleeb The Fantastique) Date: Sat Jan 08 23:11:22 CST 1994 Gads.. my apologies to those people who haven't seen stereogram images before. I've gotten a few mail inquiries as to how to read those 3-d pics I posted. Hopefully, I can help a few people here... Generally, the x's at the top of the gibberish you see are your guides for finding the background (usually) layer. If you look 'past' the X's, trying to get two of the x's to overlap each other, then get your eyes to focus on the lettering so they don't look so blurry, you may be able to see the images that are hidden in the gibberish below. This is the best trick I can think of to explain what you need to do.. they are not uuencoded files, and they are not set to any super-special format that requres another machine or program to see. You just need to figure out how to view them.. and that can take a little while, training your eyes to do weird stuff. Someone else asked me how I did these things... Someone uploaded a uuencoded file here that contained mk3d.zip. Unfortunately, mk3d.zip held an executable that works on an MS-DOS machine .. and I'm using an Amiga 500. Fortunately, the person also included the source code for the program. Unfortunately, the source code was written in C, and I don't have a C compilor handy. Fortunately, I'm a fairly bright person, and can convert C code to E code, if I have to (E being the language I've been working with the most on the Amiga.. it's really nice, although it has a few limitations at the moment). Unfortunately, the differences between the languages made the job sorta hard, and it took me almost 2 full days of debugging and screwing around to get my own version of mk3d work for the Amiga. Fortunately, when I was done, I came up with an executable that was less than half the size of the MS-DOS executable, and had a few extra functions it could do over the original. So.. if you own an Amiga, and you have access to ftp, look Real Soon Now (c) by Some Other Person, Inc. for mk3d.lha to appear at the aminet sights... you'll be able to make these yourself. mk3d for Amiga... another fine product of the Cheese Olfactory Workshop. - Trey -- If this address doesn't work, try jvanriper_uncavx_unca_edu_ /\/\ PGP key signature = 42 6E 5B EC 54 F5 8E 90 78 B5 0F 37 FC 1D A6 28 /\/\ I can see clearly now the fallout's done.

The technique that works best for me is to pretend to focus on the BACK of your terminal. Pretend that you can see completely through to the electron gun at the back of your tube. As you do that you'll see the picture start to "swim" around & then you'll see shapes that "jump out" at you. Good luck, Ron P.S.

I'm glad you liked them... the planet one, if you haven't looked carefully, has another planet set under the 'background' (without a ring). This other planet (meant to be a sort of large 'moon') is to the left of the other planet (your left, that is).

OK, so now how do one eyed people, like myself view them??? Does anyone really think these qualify as ascii art? Being as I can't make anything out, I guess I can't really judge.

Same here, I keep having the idea that I'm being fooled, and that it's just a lot of gibberish. I'm not totally one-eyed (one sees 20% the other 120% of normal), but apparently enough not to be able to see any sense in these pics. And it's not that I can't do the focussing right, cause I'm very good at forcing my eyes into unusual focusses (is that a word?) and I'm sure I'm doing everything correctly. Or is there anybody else out there with a 'lazy' eye, who has some advice as to how to view these pics. -Tob From: s1171180_giaeb_cc_monash_edu_au (Rowan Crawford) Date: Mon Jan 10 09:36:36 CST 1994 [about how to focus the 3D pics...] Ok, I've been viewing these types of things for years, so I guess it's a bit easier for me, but here's how to do it: Start by working on the X's at the top only. The best pic would be one with the X's closer together (the man/woman have them far apart so they're harder). Cross your eyes so that the X's in the middle come together in the middle: X X (this is on the screen) X (this is what you get when you cross your eyes) Now adjust your head orientation so that the two X's perfectly line up. You now have to try and focus on this ONE object. This is exactly how REAL 3 dimentionality works, so it's not too hard. When you get that focused, you should realise that it actually looks like it is sitting /out/ of the page. Once you have this, practice shifting focus between the X and something in the background (but not in the main pic). This shifting abilty is neseccary to get the right effect with the pics. Ok, now yo have that down, move down to the main pic. If you have a look at it, you'll see large repeasting patterns the same distance apart as the X's. So go into cross eye'd focus again and try to get one part in focus. The pics are made from several layers and the idea is to try and separate these layers in your mind. If it helps, here's some quite ideas of what the pics look like: the naked woman:: -oo- )( || The arms, body and legs ar in one plane (the object is actually located over on the right of the mess) with the "area between the legs" being into the screen with the background, and the breasts are actually two more layers in front. the naked man:: \i/ oo Hmm, looks like two legs sticking up in the air with the penii in the middle facing upwards and the balls (for lack of a different term) sitting out another plane. Planet:: _ <(_)> I big slightly oval object in the center (one plane) witha ring going around it (like saturn) which sits out another level. the bat and ball thing:: o o \ o A bat going up at an angle with three balls around it at different levels. All these are just SHAPES, not a shaded ascii pic or anything like that. Once you get the hang of it, they do look really cool and you can actually view them with very little effort at all. Hope that helps, Row. From: jaker_csugrad_cs_vt_edu (Jacob Rose) Date: Mon Jan 10 14:56:31 CST 1994 Bill C.

You can't; all these images are are depths, so without stereoscopic vision it's impossible to see them. You could write a program that could crank out a page of depths based on what's in the image, having it search out matching points and generate the depths from them, but it would be a royal pain... jacob rose_____________________________________________jaker_csugrad_cs_vt_edu e v o l u t i o n i s b e a u t i f u l 224 payne hall virginia tech blacksburg virginia 24060-0008.......703/232-5955 From: rbeck_island_csc_ti_com (Ron Beck) Date: Mon Jan 10 10:34:53 CST 1994 In article <14109_dirac_physics_purdue_edu>, bcr_bohr_physics_purdue_edu (Bill C .

Points that are close have a greater divergence than points that are distant (or is it the other way around). Having only one eye deprives you of viewing these just as it deprives you of depth perception in the "real" world. Here's another example of an ascii stereogram which is viewed in the same way as the SIRDS. This shows the word far as away from you and the word near as close to you. Note that there are more "n"s than there are "f"s which will make the "n"s look closer. Subject: A genuine ASCII stereogram! Here's an ASCII single image random dot stereogram for your enjoyment. To get the 3d effect, you need to diverge (unfocus) your eyes such that two adjacent letters in the same row come together. To help you focus, try to make the two capital O's at the top look like three. Once you've done that, the rest of the image should jump out of the screen at you! O O n n n n n n n n n n n n n n n n n f f f f f f f f f f f f f f e e e e e e e e e e e e e e e e e a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a a r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r r The other example I really like is this "room". Try moving your head back from the screen and moving it about a bit once you have focused on the image to increase the stereo effect even more. Have fun! Perhaps we can have a whole series of these!

Is it just me? no. i think that the monitor glows and that it is under glass has a lot to do with how easy it is to view these things on a computer. i think if you print them out and want to view them, do it in strong light, (backlit might be best) and under glass, so you can focus on the reflections. try to print them out on a good printer so the letters are DARK. i've printed them out, and haven't been able to view them either. those are my ideas on how you might be able to do it. don't forget to get really close to the picture. you should probably hang the picture or prop it up so it isn't lying flat, but is vertical. oh well. those are my ideas. -- _____ _____ _____ _____ _____ _____ |\ /| |\ /| |\ /| |\ /| |\ /| |\ /| david berner | O | | O | | O | | O | | O | | O | biology major |/_\| |/_\| |/_\| |/_\| |/_\| |/_\| dcberner_host0_colby_edu From: OSTRIDGE_venus_cc_hollandc_pe_ca (LISA OSTRIDGE) Date: Tue Jan 11 08:09:19 CST 1994 I thought that the 3-D pics were really amazing. The technique that I used to figure them out was to pick a spot on my reflection in the monitor. Focus on this one spot. ( Works especially well when wearing a light colored shirt ). Let your eyes gradually go out of focus. The picture gradually appears. Hope that this helps. Birdie From: me90drj_brunel_ac_uk (DR J) Date: Tue Mar 22 05:00:01 CST 1994 Todd D.
