Multiresolution representations (MR) for curves and surfaces have been extensively used in many areas of computer graphics.

The conventional MR is usually defined based on wavelets. However, in this lecture, I present a simple reverse subdivision approach for MR, and derive multiresolution filters for quadratic and cubic B-splines curves. I also show how to use and extend these filters for tensor-product surfaces, and 2D/3D images. Finally, some example applications in model synthesizing and contextual void patching for digital elevation models are discussed.
