kochanekBartels(pt1: Vec2, pt2: Vec2, pt3: Vec2, pt4: Vec2, tension: number, continuity: number, bias: number): Vec2
A second order function returning an evaluator for the given 2D Kochanek–Bartels curveparampt1 Previous point
parampt2 First point
parampt3 Second point
parampt4 Next point
paramtension The tension of the curve, [-1..1] from round to tight.
paramcontinuity The continuity of the curve, [-1..1] from box corners to inverted corners.
parambias The bias of the curve, [-1..1] from pre-shoot to post-shoot.
returnsA function which gives the value on the 2D Kochanek–Bartels curve at t
