Bézier Representation of Trim Curves [chapter]

D. Lasser, G.-P. Bonneau
1995 Geometric Modelling  
The composition of Bezier curves and tensor product Bezier surfaces, polynomial as weil as rational, is applied to exactly and explicitely represent trim curves of tensor product Bezier surfaces. Trimming curves are assumed tobe defined as Bezier curves in surface parameter domain. A Bezier spline approximation of lower polynomial degree is built up as weil which is based on the ' exact trim curve representation in coordinate space.
