Claim 5:
6. The method of claim 1 further including:
producing a surface mesh representation of the 3D structure;
wherein producing the volume mesh representation of the 3D structure includes producing the volume mesh representation of the 3D structure based upon the surface mesh representation of the 3D structure;
producing a 3D image scan data model of the 3D structure that includes 3D viscoelasticity information that indicates viscoelasticity at 3D locations within the 3D structure;
wherein producing the surface mesh includes producing based upon the 3D image scan data model;
further including:
determining viscoelasticity values that correspond to surface vertices of the primitive volumetric cells and determining viscoelasticity values that correspond to internal vertices of the primitive volumetric cells based upon the 3D viscoelasticity information of the 3D image scan data model;
wherein determining deformation of the volume mesh includes determining deformation as a function of the viscoelasticity values determined to correspond to the surface vertices and to internal vertices.
