Claim 27:
28. A method to produce, in a computer memory, a volume mesh structure of 3D model, the method comprising:
sorting surface vertices and internal vertices of primitive volumetric cells of a volume mesh structure that represents a three-dimensional (3D) model, to configure a memory according to a unified mesh structure including:
a list of three dimensional (3D) locations of surface vertices of the primitive volumetric cells of the volume mesh structure; and
a list of 3D locations of internal vertices of the primitive volumetric cells of the volume mesh structure; and
using a data structure that includes at least one base address pointing to a list comprising the first sub-list and the second sub-list, a count of surface vertices in the first sub-list, and a count of internal vertices in the second sub-list to store the list of three dimensional (3D) locations of surface vertices of the primitive volumetric cells of the volume mesh structure and to store the list of 3D locations of internal vertices of the primitive volumetric cells of the volume mesh structure in the computer memory, wherein the at least one base address is used for accessing the first sub-list and the at least one base address and the count of the surface vertices in the first sub-list are used to access the second sub-list in the computer memory.
