Question

Use de Casteljau algorithm to find P(0.4, 0.6) on a Bezier surface with following control points. (Only for “Y”)   P00 = (2,3,6)    P01 = (3,1,5)    P02 = (6,7,5)    P03 = (8,1,2)   P10 = (3,6,7)    P11 = (4,2,1)    P12 = (4,7,2)    P13 = (5,4,3)   P20 = (5,6,1)    P21 = (6,7,2)    P22 = (3,4,2)    P23 = (6,5,3)   P30 = (6,3,2)    P31 = (5,6,2)    P32 = (4,6,7)    P33 = (8,3,2)
