Wired has an exclusive video look at how sequences from Half-Blood Prince were converted into 3-D for IMAX screens.

“The first step is masking out objects in the scene so that we can turn those objects 3-D,” says IMAX’s Eric Robinson as he shows off the software. “The next step is, re-create the scene in 3-D so that we can generate depth information from that. Our proprietary render system generates a new image, which is offset from the original.”
