safeDerivative

fun safeDerivative(p0: Vector2, c0: Vector2, p1: Vector2, t: Double): Vector2(source)

Similar to derivative but handles cases in which p0 and p1 coincide.

fun safeDerivative(p0: Vector2, p1: Vector2, p2: Vector2, p3: Vector2, t: Double): Vector2(source)

Similar to derivative but handles cases in which p0 and p1 or p2 and p3 coincide.
