Stereogram Depth Masks
The software that creates a stereogram must be told the depth (z-dimension, into
the screen) of every pixel in the resulting stereogram.
The typical way to provide that information is with a gray-scale image (called a
depth mask) of the 3D object to be contained within the stereogram. The color
of each pixel in the depth mask determines the depth of the object's features.
Here is a selection of various depth masks used in stereograms. I've accumulated
these as I've learned about stereograms. Unfortunately I did not track where they
came from. Over the next few weeks (today is 30 April 2006) I'll try to locate the
sources and post credits as appropriate, as well as remove any images for which I
cannot get approval to post.
