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

Spherically linearly interpolate between q0 and q1.

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

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

GF_API std::ostream& operator<<	(	std::ostream &	,
		GfQuatd const &
	)

Output a GfQuatd using the format (re, i, j, k)
