Hierarchical multiresolution reconstruction of shell surfaces
Bajaj, CL; Xu, GL; Holt, RJ; Netravali, AN
AbstractWe present an adaptive, hierarchical Hh-multiresolution reconstruction algorithm to model shell surface objects from a matched pair of triangulated surfaces. Shell surfaces are an interval of contours of trivariate functions with prismatic support. In the H-direction, a hierarchical representation of the scaffold is constructed. For any adaptively extracted scaffold from the hierarchy, a sequence of functions in the h-direction (regularly subdivided mesh) is constructed so that their contours approximate the input shell to within a given error epsilon. The shell surfaces can be made to capture sharp curve creases on the shell while being C-1 smooth everywhere else. Using an interval of isocontours of smooth trivariate spline functions, rather than a pair of inner and outer surface splines, one avoids the need for interference checks between the inner and outer surface boundaries.
