Sculptured Surface Design and Implementation by Lofting Design Method Using Cross-sectional B-Spline Curves

This research presents a particular designing strategy for a free form of surfaces, constructed by the lofting design method. The regarded surfaces were created by sliding a B-spline curves (profile curves), in addition to describing an automatic procedure for selective identification of sampling p...
