# Syntax

C# |
---|

public static double Triple( Vector3d a, Vector3d b, Vector3d c ) |

Visual Basic (Declaration) |
---|

Public Shared Function Triple ( _ a As Vector3d, _ b As Vector3d, _ c As Vector3d _ ) As Double |

Visual C++ |
---|

public: static double Triple( Vector3d^ a, Vector3d^ b, Vector3d^ c ) |

#### Parameters

- a
- Type: ceometric.VectorGeometry..::.Vector3d

The left 3d vector.

- b
- Type: ceometric.VectorGeometry..::.Vector3d

The middle 3d vector.

- c
- Type: ceometric.VectorGeometry..::.Vector3d

The right 3d vector.

#### Return Value

Returns the triple product [a,b,c] of three 3d vectors.# Remarks

The triple product [a,b,c] is equivalent to a * (b x c), where

- * denotes the dot product Dot(Vector3d, Vector3d) and
- x denotes the cross product Cross(Vector3d, Vector3d)

The triple product is the determinant of the matrix formed by the column vectors a, b, c.
