Hypothesis: I can hand-draw a stereogram!

Conclusion: You tell me! Can you see it 3d?

#stereogram

@noneuclideandreamer the last one is hard, perhaps some clues on the outside could help the eyes align.
@shironeko I mean the angle of the last one is so that you basically only see one face...
@noneuclideandreamer yeah so my eyes naturally want to align the front face but that's slighty too far apart for stereo.

@shironeko Hmm, that of course highly depends on the size of your screen...

My little squares are 0.5cm. I assumed for my calculations an eye distance of 8cm and a eye-screen distance of 32cm. But intererestingly it seems to kinda work for different zoom factors.

@noneuclideandreamer First two look good.

For the third, the shaded base is a bit odd. The stereograms that I'm used to don't have filled regions - it's hard to track between the eyes.

I don't think the fourth works. I think the sides mean that the "trick" is revealed, and the lack of other clues breaks the 3d illusion.

@loopspace Yeah the colored bottom makes it weird.

And the perfect angle of the last doesn't work...

@noneuclideandreamer As others said, the third one is a bit troublesome. The others, pretty good.

I think the grid lines throw it off a bit. the cubes are rendered opaque but you can see the grid through them. if you drew the cubes as full wire frames, or did it on plain paper, might improve things.

@bit101 Interesting... I think of the cubes as behind the grid...
@noneuclideandreamer ah... that would work. :)
