[inline]

aiQuaternion::aiQuaternion	(	float	_w,
		float	_x,
		float	_y,
		float	_z
	)			[inline]

aiQuaternion::aiQuaternion

(

const aiMatrix3x3 &

pRotMatrix

)

[inline]

Construct from rotation matrix.

Result is undefined if the matrix is not orthonormal.

aiQuaternion::aiQuaternion	(	float	rotx,
		float	roty,
		float	rotz
	)			[inline]

Construct from euler angles.

aiQuaternion::aiQuaternion	(	aiVector3D	axis,
		float	angle
	)			[inline]

Construct from an axis-angle pair.

aiQuaternion::aiQuaternion

(

Member Function Documentation

aiQuaternion & aiQuaternion::Conjugate

(

)

[inline]

Compute quaternion conjugate.

aiMatrix3x3 aiQuaternion::GetMatrix

(

)

const [inline]

Returns a matrix representation of the quaternion.

void aiQuaternion::Interpolate	(	aiQuaternion &	pOut,
		const aiQuaternion &	pStart,
		const aiQuaternion &	pEnd,
		float	pFactor
	)			[inline, static]

Performs a spherical interpolation between two quaternions and writes the result into the third.

Parameters:

	pOut	Target object to received the interpolated rotation.
	pStart	Start rotation of the interpolation at factor == 0.
	pEnd	End rotation, factor == 1.
	pFactor	Interpolation factor between 0 and 1. Values outside of this range yield undefined results.

aiQuaternion & aiQuaternion::Normalize

(

)

[inline]

Normalize the quaternion.

bool aiQuaternion::operator!=

const aiQuaternion &

o

)

const [inline]

aiQuaternion aiQuaternion::operator*

(

const aiQuaternion &

two

)

const [inline]

Multiply two quaternions.
