> But maybe the trick is doing the calculation of the points that make up the curve separate, but strangely i thought they all had effect on eachother, but maybe that is not how Bezier curves work. I was so sure that what i programmed in both basic, pascal and java did take any number of points. It seem strange to me that only the neighbour point would affect the full curve?
