So, shadowwolf... what the f*ck is a stereogram, and why do they all look similar?
What is a stereogram?
According to
Wikipedia: An optical illusion of depth created from flat, two-dimensional image or images.
In my terms its a 3D object (dept mask) hidden in a 2D image (e.g. wallpaper/ textured images, etc.)
Most of the stereograms i create are random dot stereograms and autostereograms.
locopuyo " Magic Eyes" is an optical illusion book that contains stereograms.
Why do they all look similar?
You are referring to the pattern repeating, right?
Once again according to
Wikipedia " If, over some area of the picture, the pattern is repeated at smaller distances, that area will appear closer than the background plane. If the distance of repeats is longer over some area, then that area will appear more distant (like a hole in the plane)."
This explains that the more repeating image/texture gives more dept to the 3d image and how one' s eyes can visualise the 3d object hidden.
But this depends on the type of stereogram one is creating.
