Methods

CalculateCubicSpline(int, Vector3[])

Calculates the natural cubic spline of the control points. The segments are represented as: a + bu + cu^2 + d*u^3 algorithm adopted from: http://www.cse.unsw.edu.au/~lambert/splines/.

Declaration
public static Spline[] CalculateCubicSpline(int n, Vector3[] v)
Parameters
Type Name Description
int n

the number of control points.
Vector3[] v

the array of vectors.
Returns
Type Description
Spline[]

The spline.

CalculateCubicSpline(ref int, ref Vector3[], out Spline[])

Calculates the natural cubic spline of the control points. The segments are represented as: a + bu + cu^2 + d*u^3 algorithm adopted from: http://www.cse.unsw.edu.au/~lambert/splines/.

Declaration
public static void CalculateCubicSpline(ref int n, ref Vector3[] v, out Spline[] c)
Parameters
Type Name Description
int n

the number of control points.
Vector3[] v

the array of vectors.
Spline[] c

The c.

GetPointOnSpline(float)

Evaluate the point using a cubic equation.

Declaration
public Vector3 GetPointOnSpline(float s)
Parameters
Type Name Description
float s

A distance.
Returns
Type Description
Vector3

The point.
