No complicated set-up. But I need 3D curve because it uses all the 3 axis to define the shape. Once again, you already had the drawing part in your code, what it's missing is the curve definition (and that, of course, is a pure mathematical thing and has nothing to do with OpenCV). newest bezier-curve questions feed Computer Graphics. Now, I am testing on some points. The curve always passes through the first and algorithm is first shown to be a blend of vanilla gradient descent and Gauss-Newton iteration. Simon Cozens Posts: 324. The control points for the smoothing algorithm will be placed on the tangent line, and their displacement from the curve point will control the curve appearance.
