| Abstract: | carving , for visibility preprocessing of unrestricted (nonaxial) models. It is different from visibility preprocessing applied directly
to nonaxial data. As a sculptor carves a statue, carving splits the nonaxial portion of a model, and results in a model with
only axial polygons and a set of cuttings. The visibility information of the carved axial model can then be computed with
the cuttings as detail objects. |
