For my project I need two things: 1) to create a Bézier curve (or any curve, for that matter) 2) for a ball to follow that curve
My initial plan was to draw an ellipse with the center in the ball and find the intersection between this ellipse and the curve (which I will have two, as the radius of the ellipse will be just outside that of the ball). However, then it dawned on me that even though I can DRAW a curve - I don't have its explicit function, so I won't be able to find any intersection at all.
What if it is not a curve - but some optional path drawn by the user? I won't be able to calculate its function easily as well.
What might be the standard procedure? Creating waypoints and approximating any path to a set of lines?
