DESCRIPTION
.LP
.LP
This program is part of Netpbm.
.LP
\fBppm3d\fR reads two PPM images as input and produces a PPM as
output, with the images overlapping by \fIhorizontal_offset\fR pixels
in blue/red format. The idea is that if you look at the image with
3-D glasses (glasses that admit only red through one eye and only green
through the other), you see an image with depth. This is called a
stereogram.
.LP
\fIhorizontal_offset\fR defaults to 30 pixels. The input PPMs
must be the same dimensions.
.LP
To make a different kind of stereogram, use \fBpamstereogram\fR.
That makes a steregram that you view without special glasses, just by
letting your eyes unfocus so that each eye sees different parts of the
image.
