abstract
The problem of planar mapping and deformation is central in computer graphics, where applications range from image warping and character animation, to non-rigid registration and shape analysis. I will present a framework for adapting general, smooth, function bases for constructing provably good planar mappings. The term "good" in this context means the map has no fold-overs (injective), is smooth, and has low isometric or conformal distortion. Our approach bridges the gap between mesh and meshless methods, allowing us to construct meshless maps with bounded distortion.
