Abstract
This paper provides four alternative sets of discrete conditions, which ensure that a patch of a parametric tensor-product B-spline surface is locally convex. These conditions are at most of degree six with respect to the control points of the surface. Their weakness is analytically investigated and graphically illustrated for a bicubic B-spline surface of industrial interest.
