| Abstract: | In this paper, two explicit conversion formulas, which are different from these in 1],2] and 3], are derived between Bezier rectangles and Bezier triangles, by using the eleva-tion operator aod the difference operator. Two corresponding efficient and stable algorithmswith comparisons with other algorithms are also presented. In the cases of lower degree inpractical use straightforward results are presented. |
