Bezier's surface

Bezier's surface for operative network M with parameters (m+1) x (n+1) dots is defined by parametric formulation: where are Bernstein polynom for u and v̼ <0,1>.

$$$APPLET

Applet: Bezier's surface, select with a mouse one from command point in left-top and move it with a key: in line of axis x (q , w -), in line of axis y (e +, r -), in line of axis z (t +, y -), with keys 1-6 you can change axonometry
