WebJul 8, 2024 · The control points are on lines that are tangent to the circle, so they are at right angles to these radial vectors. A vector at a right angle to another is simply the original vector with the X and Y coordinates swapped and one of them made negative. Here's the program running with different angles: WebThe goal of LeGrange interpolation is to create a smooth curve that passes through an ordered group of points. When used in this fashion, these points are called the control points. The general idea, as with all curve algorithms, is to use the control points to generate parametric equations.
