Rational Bezier surface is a common fitting tool in Computer Aided Geometric Design. The injectivity of curve/surface implies the one-to-one property and there is no self-intersection of curve/surface. In this paper, we propose a geometric method for checking the injectivity of rational Bezier surface based on its control points. (C) 2015 Elsevier Ltd. All rights reserved.
