For me they alternate between flickering, seeing only one colour and a weird
'both at the same time' effect, I can't get the blend thing at all.
Interesting how the squares end up being purple and the *'s teal.

One of my 'dream projects' is a game which would play with nonidentical stereograms like this.

I don't think it is really possible to blend those two colors because the light/contrast information is too dissimilar between the two and the light/contrast information is predominent over the color information in our vision. So the mind is forced into discriminate mode.

Do they have the same Value and Saturation? Cause that might help a bit

I can't really consistently do stereograms or magic eye puzzles Sad

I can't do crosseyed stuff at all, it seens! I decided to try to separate the image in 2 and animate them with 1 frame of pause and it worked, or so I think. Not sure if what I am seeing is red-yellow or just orange. Pretty ballin' though.

Yeah, I get this. If I focus on a specific point in the image, and don't let my eyes move from that spot, they eventually settle to a single solid color. It's not a blend of the two colors, just one of the original colors.

However, if I move my eyes around the image, I get the flickering effect.

Actually the real 3Ds has only 256 colors, they can fake 56026 colors using this technique

Please tell me you're making a stereogram rogue.

Any and every game I'll make will be 3D (as in, viewable as stereo) because it's easy as long as you do it from the start. Then when we get mass 3D displays most of the work is already done.

I'm one of those lucky people who can do 'snake-eyes', which is like the opposite of crossing your eyes and involves forcing your vision together without actually staring at your nose etc.
Makes stereograms instantly work for me.

Edit: apparently it's called binocular fusion. It involves splitting vision naturally into two parts and overlapping the resulting afterimage. Most people can do it in childhood and lose the ability later.
Can anyone else here still do it? I haven't even thought about it in a long time.

I'm not sure what you're talking about, but I can cross my eyes instantly and with ease (in fact, they tend to do that on their own... I have corrective glasses for this). Keep 'em crossed, concentrate on either image, control the degree of crossing. No need for noses.

Do they have the same Value and Saturation? Cause that might help a bit

No, just randomly picked a teal to go with the purple.

Fixed.

Made no difference in terms of the effect, but it looks less like bright magic and more like a hologram.

This is the next 3DS visual gimmick

I'm hoping it's a next visual gimmick for 3D displays in general, whenever we get them. I mean, it's pretty easy, you just need two color variations of the same texture (might seem that's twice as much work, but there's also specular, normal and illumination maps).



The effect itself is mostly limited to holograms and magic, though. I've tried using it to create subtle lighting effects, fire, etc. but it doesn't work that way.

Certain things in nature produce this effect, such as certain fish and insects. Their body reflects light differently from different angles, thereby sending a different color to each eye.

Where the heck did 56026 (from earlier) come from, moi?

For that matter, where did 64770 come from o_O
