For 3D views in APOD, I would like to request stereo pairs over two-color stereo anaglyphics, and I'd like to know what others think. The stereo anaglyphic red/blue pictures give some sense of the third dimension, but they are monochrome, and they never seem to look right to me through the colored glasses. They seem more appropriate for comic books than for real pictures. On the other hand, stereo pairs can be in either monochrome or color, and they can show more detail. Your visual cortex isn't always fighting the red/blue preference. Of course, unless you are nearsighted, they also require special glasses to view.
A long time ago, NASA published a wonderful book of the Mars landscape (The Martian Landscape, by the Viking Lander Imaging Team, 1978) that included 3D visuals, all in stereo pairs. If you've ever studied geology, you know that stereo images showing topography are always in stereo pairs. I've thankfully never seen geological representations of topography as red/blue anaglyphic images.
I'd like to petition the editors of APOD that all future 3D views in APOD be given as stereo pairs. Comments?
