I've been thinking about that as well. My opinion is that it's NOT linear-- that
the RED/BLUE 'mix' should not be equal across the model (and/or that the
mid-point 'mix line' should not extend exactly to the mid-point of the model or
of a larger entire scene.) The analogy I thought of was the visual effect of
looking through binoculars at distant objects: The 3-D effect is reduced there;
objects at different distances look kind of like flat planes, because our eyes
are only _____ inches apart (not much parallax.) And MUCH more of a 3-D effect
looking at closer objects.
