New modeling techniques in multi-space CAD

摘要

This paper investigates new wavelet-based multiresolution modeling techniques in CAD. MRA techniques are extended to detail feature transplanting and detail feature copying from previous MRA editing including sweep editing, fractional editing, synthesis editing and detail blending. Two new editing methods called detail feature transplanting and detail feature copying are added to previous sweep editing, fractional editing, synthesis editing and detail blending. Detail feature transplanting editing is a way to transplant detail features of a curve/surface to another curve/surface. Detail feature copying editing is a way to copy or move detail features on the same curve/surface.
