inline

Returns the dot (inner) product of two quaternions.

GF_API GfQuaternion GfSlerp	(	double	alpha,
		const GfQuaternion &	q0,
		const GfQuaternion &	q1
	)

Spherically interpolate between q0 and q1.

If the interpolant alpha is zero, then the result is q0, while alpha of one yields q1.

GF_API GfQuaternion GfSlerp	(	const GfQuaternion &	q0,
		const GfQuaternion &	q1,
		double	alpha
	)

GF_API std::ostream& operator<<	(	std::ostream &	out,
		const GfQuaternion &	q
	)

Output a GfQuaternion using the format (r + (x, y, z)).
