ABSTRACT:
A method for determining data characterizing a primitive resulting after the primitive has been subjected to clipping determines the data after the primitive has been clipped. The data, which may be attribute data, is not determined prior to clipping, thereby saving processing time if the primitive is clipped entirely from view (i.e., a viewing plane displayed on a display device). The primitive initially is defined by a set of initial vertices and a set of attributes associated with the initial vertices. After each instance of clipping, the primitive becomes a resulting primitive defined by a modified set of vertices that may include a new vertex and a modified set of attributes associated with the modified set of vertices.
