contour plots can be used in mathematica to plot equations such as ellipsoids like: 1/10^2*x^2 + 1/6^2*y^2 + 1/15^2*z^2 == 1 a command like: ContourPlot3D[ 1/10^2*x^2 + 1/6^2*y^2 + 1/15^2*z^2 == 1, {x, -11, 11}, {y, -7, 7}, {z, -16, 16}] creates the ellipsoid

Attempt to find rotated QR codes and get the rotation
By thomas in UncategorizedAttempting to use zxing library to detect qr codes and its rotation.

After having read: http://groups.google.com/group/zxing/browse_thread/thread/ea911e890ea69ea5 The use of the zxing’s implementation to detect QR codes seems less promising.
