[BSplineBezier] - It is a Visual C++ 6.0 (and above) source code to draw B_Splines and Besier Curves + 3D surface and complex spline on it surface on canvas using ONLY mathematical functions and WinApi.No OpenGl fuctions are used. So you can understand internal mathematical apparatus.You can move points by mouse for redraw Bezier.Use mouse Left button to rotate 3D surface.
[bspline_tools] - this package implement a b spline algorithm in 1D 2D and 3D level. the Interpolation detail could be choose as use like.
