Abstract
A method of the degree reduction for triangular Bezier surfaces is presented by minimizing the defined distance function between the original triangular Bezier surface of degree n and the degree reduced triangular Bezier surface of degree m(m≤n-1).Continuity at corner points of triangular Bezier surfaces are considered in degree reduction process.Finally some graphical examples are shown in order to illustrate the validity of the method presented here.
