CatmullRomChain2

class CatmullRomChain2(points: List<Vector2>, alpha: Double = 0.5, val loop: Boolean = false)(source)

Calculates the 2D Catmull–Rom spline for a chain of points and returns the combined curve.

For more details, see CatmullRom2.

points

The List of 2D points where CatmullRom2 is applied in groups of 4.

alpha

The tension of the curve. Use 0.0 for the uniform spline, 0.5 for the centripetal spline, 1.0 for the chordal spline.

loop

Whether to connect the first and last point, such that it forms a closed shape.

Constructors
