I read this and several other articles to try to find out how they were applying the red and blue highlights so the anaglyph glasses will work. Unfortunately, they did not say how the images were modified. The article did say the glasses worked quite well, which brings up the question of why they are spending huge amounts of money on expensive goggles and graphics cards, when a couple of pieces of colored plastic would do the job about as well. On the other hand, I know several people that, due to physical limitations, have no stereovision whatsoever, and they have no problems maneuvering in a 3D world at all, so an effectively monochrome 3D representation produced by the anaglyph glasses may not be as necessary as NASA is implying.
