Claim One:
1. An apparatus for interactively magnifying a first texture to generate a high resolution display image, pixels of said high resolution display image having varying levels of detail, said apparatus adapted for use with an interactive computer graphics processing system, the first texture and a second texture being stored in the interactive computer graphics processing system, the first texture being of higher resolution than the second texture, said apparatus comprising: extrapolating means for using the first and second textures to generate an extrapolated frequency band approximating high frequency image information contained in a texture of higher resolution than said first texture; scaling means for scaling said extrapolated frequency band on a per pixel basis as a function of each pixel's level of detail to generate a scaled extrapolated frequency band, said scaled extrapolated frequency band approximating high frequency image information contained in a magnified image of the first texture; and image augmenting means for augmenting the first texture using said scaled extrapolated frequency band to thereby generate a magnified image of the first texture.
