....to sculpting applications, provided that a platform is available which allows storage and speedy rendering of large numbers of polygons. The four most significant polygon mesh based sculpting system are those of Parent, Allan et al., Leblanc et al., and Elson and Malone [Par77, AWW89, LPMTT91, Els90b, Els90a] Parent initiated use of the basic vertex movement decay function technique used in all of these systems. His is the only polygon mesh system that uses virtual tools. Allan advanced the use of decay functions and defined move vertex as the fundamental deformation technique; both ....

....the inventors of sculpting systems are woefully silent about the details of the smoothing techniques that they have used. The models created using Elson and Malone s S Geometry system suggest that they have used the Doo Sabin algorithm, though this is not explicitly stated in their publications [Els90b, Els90a] Allan et al. also use a smoothing decay function which appears to do a sort of averaging with no subdivision step [AWW89] although no concrete details are provided. SAM IAM offers users the option of choosing whether or not to subdivide before applying the smoothing technique. Should ....
