Patent ID: 7034824

Claim:
A method, comprising: defining a patch of vertices of a model; and determining a parameterization of a local neighborhood patch covered by a common overlap patch where two or more sub-neighborhood patches of the model partially overlap such that each sub-neighborhood has a portion that does not overlap one or more other sub-neighborhoods, wherein the common overlap patch of the sub-neighborhood patches is of sufficient size to contain a region of interest and sufficient to enable the region of interest to be moved or extended while remaining within common overlap patch, wherein the parameterization of the local neighborhood patch is determined based on the two or more sub-neighborhood patches including the common overlap patch and also based on the location of the region of interest with respect to the model, and wherein when the location of the region of interest is moved or extended with respect to the model within the local neighborhood patch the parameterization is automatically re-determined based on the two or more sub-neighborhood patches including the common overlap patch and also based on the previously presented location of the region of interest with respect to the model.
