Approximating Bézier Rectangular Surface Using Degree Elevation

Modeling Bezier surface at high degree is expensive in terms of computational time due to an excessive number of control points. This is a well-known major problem in Bézier surface construction. To significantly solve this problem, a new algorithm that can reduce computational time while remain a highly accurate result, is introduced by utilizing a simple equation to increase the number of control points. Therefore, the concept of degree elevation technique plays a key role in this study.
