Abstract :
Wavelet method has been found to be very effective in treating geometric modeling due to its properties of localization both in time/spatial and frequency domains. We discuss how wavelet multiresolution techniques can be applied to free-form feature (FFF) surface design, present one 2-stage CAD design approach combining feature concept and multiresolution representation. The approach proves that wavelet multiresolution technology is available for the extraction of FFF in the region of interest (ROI). The wavelet coefficients indicate the degree of detail in the solution; this makes feature/detail manipulation intuitive and convenient. Finally, an integrated framework of FFF surface design is given and discussed by an instance.
