Test 2D barcode readers (e.g., QR Code) by virtually printing them on small patches of 3D quadratic surfaces (e.g., ellipsoid), projecting them back to 2D, and scanning. Inspired by a barcode printed on a bottle whose shape resembled a hyperboloid of one sheet.
We don't want too extreme warpage, e.g., the surface tangent to the line of sight or even flipped backwards. What is a parametrization of quadratic surfaces that spans all possible "almost flat" patches?
Should the QR reader use detected position and alignment markers to interpolate a quadratic surface?
Analogous 1D version for regular bar codes? (Conic sections)
Repeat for higher order surfaces?
Also perspective projection.
