Problem 1a
Re-wording for the first sub-question (homework PDF updated on 10/18/2010):
"If you tilt your head sideways (i.e., tilting your head over to one of your shoulders, so that the imaginary line segment connecting your eyes is now aligned with the vertical direction), will the displayed images appear dimmer in one eye, both eyes, or neither eye? Justify your answer."
Each LCD shutter in this problem is like a giant LCD pixel, which includes two polarizers at right angles to each other, and a crystal that can be used to twist the light. The shuttering is done by selectively applying a voltage that either lets the crystal twist the polarization by 90 degrees between the polarizers (letting light through), or does not let the crystal twist the polarization at all (not letting light through).

Problem 4
Your answer should be parameterized in terms of b, as well as m and beta. (homework PDF updated on 10/26/2010)
Problem 6
The image size (and thus height h) is constant
throughout the problem. (homework PDF updated on 1024/2010)
The angle theta is between the line going to the top of
the image rectangle and the line going to the bottom of the image rectangle.
It is *not* the angle between the z-axis and the top line; that angle would
be theta/2. (homework PDF updated on 10/27/2010)
The projection matrix you solve for in part (a) should be in terms of h and theta only, no other symbols. (homework PDF updated on 10/27/2010)
