Patent ID: 7623992

Claim:
A method of generating a refined isosurface within an original volume based upon an importance function, comprising the steps of: forming an initial, regular grid within said original volume, said regular grid comprised of a multitude of uniformly spaced apart vertices; obtaining an importance function of said original volume, said importance function identifying areas of high importance and areas of low importance on said original volume; applying said importance function to said initial, regular grid to warp said regular grid modeling said original volume to form a relaxed grid having a higher Tessellation density in the areas of high importance on said original volume and having a lower Tessellation density in the areas of low importance on said original volume, said relaxed grid defining a warping function; using said warping function to return said relaxed grid to a regular grid shape within said original volume thereby warping the original volume based on said relaxed grid to obtain a warped volume; extracting a warped isosurface from said warped volume; unwarping said warped isosurface using the said relaxed grid to obtain said refined isosurface; and using said refined isosurface to form a dataset to visualize said original volume.
