| Abstract: | In this paper, some geometric properties (envelope, subdivision, variation diminishing, shape control, convexity preservence, etc.) of the rational cubic curve are given, which form the basis of the CONSURF surface lofting program, developed by Ball at the former British Aircraft Corporation (Warton). |
