)

Public Shared Function GetAngle ( 
	quaternion1 As QuaternionD,
	quaternion2 As QuaternionD
) As Double

public:
static double GetAngle(
	QuaternionD quaternion1, 
	QuaternionD quaternion2
)

static member GetAngle : 
        quaternion1 : QuaternionD * 
        quaternion2 : QuaternionD -> float 

Parameters

quaternion1

Type: DigitalRune.Mathematics.AlgebraQuaternionD
The first quaternion.

quaternion2

Type: DigitalRune.Mathematics.AlgebraQuaternionD
The second quaternion.

Return Value

The quaternions are interpreted as orientations. The result is the angle of the quaternion which would rotate an object in the first orientation to the second orientation.

The result is only valid for unit quaternions.
