Write short notes on rendering bi-cubic surface patches of constant u and v method?
The simple way is to draw the iso-parmetric lines of the surface. Discrete approximations to curves on the surface are formed by holding one parameter constant and permitting the other to vary at discrete intervals over its whole range.
This makes curves of constant u and constant v.
Differentiate among interpolation spline and approximation spline? When the spline curve passes by all the control points then it is known as interpolate. When the curve is

There are mostly two kinds of Video Tele Conference systems: 1) Desktop systems are add-ons to normal PC's, transforming them in Video Tele Conference devices. A range of variou
To prove ‾P (1) = p n Solution : since in the above case we determine each term excluding B n,n (u) will have numerous of (1 - u) i (i = 0 to n) consequently by using u = 1
