Abstract
A system and method of interactively magnifying a first texture to generate a generally unblurred high resolution display image at a particular level of detail are disclosed. The method of the present invention includes the step of extrapolating from the first texture and a second texture to generate an extrapolated frequency band. The extrapolated frequency band approximates high frequency image information contained in a texture of higher resolution than the first texture. The method also includes scaling the extrapolated frequency band as a function of the particular level of detail to generate a scaled extrapolated frequency band, wherein the scaled extrapolated frequency band approximates high frequency image information contained in a magnified image of the first texture at the particular level of detail. The method of the present invention further includes augmenting the first texture using the scaled extrapolated frequency band to thereby generate a magnified image of the first texture at the particular level of detail.
