Syntax
public struct SplineConstructors
Spline(Vector3, Vector3, Vector3, Vector3)
Initializes a new instance of the Spline struct.
Declaration
public Spline(Vector3 a, Vector3 b, Vector3 c, Vector3 d)Parameters
| Type | Name | Description |
|---|---|---|
| Vector3 | a | Point A. |
| Vector3 | b | Point B. |
| Vector3 | c | Point C. |
| Vector3 | d | Point D. |
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)
Evaluates the point using a cubic equation.
Declaration
public Vector3 GetPointOnSpline(float s)Parameters
| Type | Name | Description |
|---|---|---|
| float | s | A distance. |
Returns
| Type | Description |
