InterpolationKind

type InterpolationKind = "linear" | "cubic";

Defined in: core/interpolation.ts:18

Types of interpolation supported.

Functions

splineCurve()

function splineCurve(
   prev, 
   current, 
   next, 
   t, 
   graph
): ControlPoint;

Defined in: core/interpolation.ts:41

x0,y0,x1,y1 are the coordinates of the end (knot) pts of this segment x2,y2 is the next knot -- not connected here but needed to calculate p2 p1 is the control point calculated here, from x1 back toward x0. p2 is the next control point, calculated here and returned to become the next segment's p1.

Parameters

Parameter	Type	Description
prev	default	the previous point
current	default	the current point
next	default	the next point
t	number	tension coefficient
graph	default	graph object

Returns

ControlPoint
