Nonlinear Magnification Fields

Abstract:: We introduce nonlinear magnification fields as an abstract representation of nonlinear magnification. Methods are provided for converting transformation (distortion) routines to magnification fields and vice-versa. This new representation provides ease of manipulation and power of expressiveness. We can exploit these on a number of levels: from fine-grained low-level details, to user-interfaces layered on top of our representation, to using the data itself to define the magnification.
