JPL has just started releasing stereo 3-D images taken from the IMP (imager
for Mars Pathfinder) camera. They're not bad.

Once again, I have reprocessed some of the images to increase their sharpness
-- but mostly I've resized and brightened them to maximize the 3-D effect
when viewed on a 600 x 800 (SVGA) high-color PC display. The images that
exist on our webpage are at:

I've also included instructions below on how to build some quick-and-dirty
3-D glasses. These same instructions appear on each of the stereo image
pages.

=====================================

Three-D glasses are somewhat difficult to find, but a reasonable quality
substitute can be readily synthesized using standard Cellophane that is
available at almost all arts and crafts stores. The following instructions
are for the Cellophane distributed by Bemiss-Jason. Their cellophane is
manufactured in England, so it should be readily available almost everywhere
in North America and Europe.

Place one thickness of red cellophane (Part No. 7310-0) over your left eye.
Place two thicknesses of blue cellophane (Part No. 7315-0) over your right
eye. The two thicknesses are necessary because the blue is more transparent
than the red. Nor is it as good an on-color color filter as the red. The
differences in transparencies between the two colors will leave the stereo
image somewhat red in color, but that's necessary to get good red-blue
channel separation between the two superimposed images -- and thus good
stereoscopic effect.

These images have been reprocessed from the JPL images and have been resized,
sharpened and brightened so as to maximize the 3-D effect when seen on an
SVGA (600 x 800 pixel) PC high-color (15-bits or better) display.

You will want to see as much of the image at one time as you possibly can. If
you are using a Netscape browser, go to the Options menu and deselect the
"Show Directory Buttons" and "Show Location" options. Doing this should
provide you with enough screen area to completely see all of the image.

To get the best possible 3-D effect, sit at least an arm's length away from
the screen. Be sure that the top of the image is on the screen because this
is the reference point for the 3-D effect. If it is not present, the stereo
effect will be diminished.
