Class QuaternionExtensions

Extension methods for advanced Quaternion operations. Provides interpolation methods with control over rotation direction.

Inheritance

QuaternionExtensions

Namespace: NWH.Common.Utility

Assembly: NWH.Common.dll

Syntax

public static class QuaternionExtensions

Methods

Add(Quaternion, Quaternion)

Adds two quaternions component-wise.

Declaration

public static Quaternion Add(Quaternion p, Quaternion q)

Parameters

Type	Name	Description
Quaternion	p	First quaternion.
Quaternion	q	Second quaternion.

Returns

Type	Description
Quaternion	Component-wise sum.

Lerp(Quaternion, Quaternion, float, bool)

Linear interpolation between two quaternions with optional short/long path control. Unlike Unity's Quaternion.Lerp, this allows choosing rotation direction.

Declaration

public static Quaternion Lerp(Quaternion p, Quaternion q, float t, bool shortWay)

Parameters

Type	Name	Description
Quaternion	p	Starting rotation.
Quaternion	q	Target rotation.
float	t	Interpolation factor (0 to 1).
bool	shortWay	True for shortest rotation path, false for longest.

Returns

Type	Description
Quaternion	Interpolated quaternion.

ScalarMultiply(Quaternion, float)

Multiplies all components of a quaternion by a scalar value.

Declaration

public static Quaternion ScalarMultiply(Quaternion input, float scalar)

Parameters

Type	Name	Description
Quaternion	input	Input quaternion.
float	scalar	Scalar multiplier.

Returns

Type	Description
Quaternion	Scaled quaternion.

Slerp(Quaternion, Quaternion, float, bool)

Spherical linear interpolation between two quaternions with optional short/long path control. Provides smooth rotation interpolation with control over rotation direction.

Declaration

public static Quaternion Slerp(Quaternion p, Quaternion q, float t, bool shortWay)

Parameters

Type	Name	Description
Quaternion	p	Starting rotation.
Quaternion	q	Target rotation.
float	t	Interpolation factor (0 to 1).
bool	shortWay	True for shortest rotation path, false for longest.

Returns

Type	Description
Quaternion	Interpolated quaternion.
