summary 
This article develops a special case of the Betaspline curve and surface technique called the Beta2spline. While a general Betaspline has two parameters (B1 and B2) controlling its shape, the special case presented here has only the single parameter B2. Experience has shown this to be a simple but very useful special case that is computationally more efficient than the general case. Optimized algorithms for the evaluation of the Beta2spline basis functions and rendering of Beta2spline curves and surfaces via subdivision are presented. This technique is proving to be quite useful in the modeling of complex shapes. The representation is sufficiently general and flexible so as to be capable of modeling irregular curvedsurface objects such as automobile bodies, aircraft fuselages, ship hulls, turbine blades, and bottles
