Claim 19:
20. A data storage and retrieval system for a computer memory comprising:
sorting means for sorting surface vertices and internal vertices of primitive volumetric cells that include both surface vertices and internal vertices, included within a volume mesh structure that represents a three-dimensional (3D) model, to configure said memory according to a unified mesh structure, said unified mesh structure including:
a first list including 3D locations of surface vertices of primitive volumetric cells included within the volume mesh structure; and
a second list including 3D locations of internal vertices of primitive volumetric cells included within 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 first sub-list and to store the second sub-list 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.
