three-d display menu

--------------------------------
This menu is for displaying greyscale images in three dimensions, using a technique similar to the old 3D movies, with the funny glasses and all. The idea is that you can display one greyscale image, using another greyscale image to represent the altitude at which pixels from the first image are displayed. Put more succinctly, the first image encodes surface intensity, the second, altitude. The system presents a display that must be viewed with 3D glasses (the kind with a red filter on the right eye and a blue filter on the left eye).

The menu operates as follows:

  1. Enter the name of the first greyscale image in the B&W image menu field. This is the image that encodes surface intensity.
  2. Enter the name of the image that encodes altitude in the Altitude image menu field.
  3. Enter the amount of parallax you want in the Maximum shift menu field. A good starting value is 20. Higher values may cause the undulations of the surface to appear more starkly.
  4. Enter the width you want for the image in the Display width menu field.
  5. Click on DISPLAY.
