Knee Modeling

3. Knee Modeling

Reconstruction Algorithm

(a) Points extracted form CT volume via isosurfacing. (b) Alpha-solid of points in (a). (c) Signed distance function.
(d) Supporting tetrahedral mesh and surface A-patches approximating the surface of the alpha-solid. (e) Reconstructed surface model of the distal end of the femur.
