QuaternionD.Invert Method

QuaternionDInvert Method

Inverts the quaternion.

Namespace: DigitalRune.Mathematics.Algebra
Assembly: DigitalRune.Mathematics (in DigitalRune.Mathematics.dll) Version: 1.14.0.0 (1.14.0.14427)

Syntax

C++

Copy

public void Invert()

Public Sub Invert

public:
void Invert()

member Invert : unit -> unit

Exceptions

Exception	Condition
MathematicsException	The length of the quaternion is zero. The quaternion cannot be inverted.

Remarks

The (multiplicative) inverse of a quaternion is calculated by using the following formula:

q^-1 = q^* / (q q^*) = q^* / N(q)

The inverse of a unit quaternion is the same as its conjugate. You might consider using the method Conjugate because it is faster than Invert.
