Implementing iBooks page curling using a conical deformation algorithm
One of iPad's most talked about apps is Apple's own iBooks e-reader. Perhaps its most eye-catching but completely superfluous feature is the beautiful, dynamic page curling effect that follows your finger naturally as you drag to turn pages. Unlike cheap implementations using simple masks and gradients, iBook's page curling is very realistic, with content that bleeds through and deforms accurately

The metaballs don't have generated UV coordinates, and tangents can't be calculated with the usual method because it relies on texture coordinates.
