Subject: Create your own 3-D Mars images
Date: Thu, 17 Jul 1997 12:07:12 -0500
Hello LFM & Red Rover Enthusiasts,
If you were excited about viewing the 3-D stereo images from
Pathfinder, you might be interested to learn that you can create such
images on your own computer. The really GOOD news is that if your students
created a Martian landscape for the Red Rover project, you probably already
have all the tools you will need.
By taking two side-by-side ( 1-2 inches apart ) pictures from your
QuickCam ( already mounted on your Lego Dacta rover ) and saving them as
grayscale, you can then use the free software program NIH Image to stack
them, add a third all black slice, and then convert RGB to 8-bit color.
Convert to gif or jpeg and your students can even share their stereo images
with others on the web. You will need blue-red glasses to see the 3-D
effect.
Please e-mail back if you need more detailed instructions.
Happy to Contribute,
Tim McCollum
