AngleCosine Method
Computes the cosine of the angle between two 3d vectors.

Namespace:  ceometric.VectorGeometry
Assembly:  ceometric.VectorGeometry (in ceometric.VectorGeometry.dll) Version: 1.8.0.0 (1.8.0.0)

Syntax

C#
public static double AngleCosine(
	Vector3d a,
	Vector3d b
)
Visual Basic (Declaration)
Public Shared Function AngleCosine ( _
	a As Vector3d, _
	b As Vector3d _
) As Double
Visual C++
public:
static double AngleCosine(
	Vector3d^ a, 
	Vector3d^ b
)

Parameters

a
Type: ceometric.VectorGeometry..::.Vector3d
A first 3d vector.
b
Type: ceometric.VectorGeometry..::.Vector3d
A second 3d vector.

Return Value

Returns the cosine of the angle between two 3d vectors.

Remarks

The computation of the cosine of the angle is numerically more stable and computationally less costive than the computation of the angle.
