Abstract:
1. A computer-implemented method comprising: providing a first texture map for a first portion of a three-dimensional surface, the first texture map being associated with a first mapping technique; providing a second texture map for a second portion of the three-dimensional surface, the second texture map being associated with a second mapping technique that is different from the first mapping technique; providing a third texture map for a third portion of the three-dimensional surface, the third texture map being associated with the second mapping technique; and generating a multiple-component map set that includes at least a portion of the first, the second and the third texture maps, the first texture map including cylindrical projection information, the second texture map including azimuthal projection information, the third texture map including azimuthal projection information, the first portion separating the second portion and third portion, the cylindrical projection information including plane-chart projection information, and wherein the providing the first texture map includes hexagonally re-parameterizing the cylindrical projection information using a linear transform.
