"Webpasses through the first control point, and ends up at the last control point (i.e., the endpoints are “pinned”). In between, the curve passes near the control points but doesn’t go through them. If the number of control points is equal to the order, then moving any control point changes the shape of the entire curve2. If we have " - Control point in computer graphics

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: WebA common application for these curves in computer graphics is the creation of a smooth flight path that passes through keyframe points in space. The basic issue is how to derive the tangent vectors for each piece of the curve. There are two ways one might achieve this that are illustrated in the drawings below.
