Environment Map Morphing
R. A. Manning and C. R. Dyer,
Computer Sciences Department Technical Report 1423, University of Wisconsin - Madison, December 2000.
The techniques of static and dynamic view morphing are extended to allow for (1) interpolation between arbitrary, uncalibrated environment maps (complete or partial), (2) camera motion directly towards or away from the scene (so that the epipole is visible), and (3) views of dynamic scenes in which an object's vanishing point is visible inside the object. It is shown that, by using an image cylinder instead of an image plane, the scanline property can be preserved and the morphing process can be made continuous for environment maps. Environment map interpolation together with layering provides an uncalibrated, sprite-like graphics primitive similar to ``billboarding'' techniques.
