Bezier Curve Algorithm Explained The algorithm takes a series of points on the x-y graph. This version of the algorithm displays it as a bunch of line segments, the exact number determined by the number of subdivision the coder chooses. For each iteration of t, the weight of each coordinate is added to find the point. 1) I suppose you mean "a way to do Bezier curves with Matplotlib", in contrast e.g. with Tkinter canvas, PyPI bezier 0.8.0, etc. Numpy offers just a method of creating arrays. 2) There&39;s no need for ntimes1000. It&39;s a total waste and inefficient programming. The same result is achieved with ntimes50. Drawing a cubic bezier curve out of any SVG or CANVAS frame. 1) interpolating 4 points The Bzier curve is defined as an array of 4 given points, each defined as an array of 2 numbers. The bezier function returns the point interpolating the 4 points. def bezier def bezier.interpol lambda a0 a1 a2 a3 t u round a0 u u u 1.
