GfDot()

GfHalf GfDot ( const GfQuath &  q1, const GfQuath &  q2  )

inline

Return the dot (inner) product of two quaternions.

GfSlerp()

GF_API GfQuath GfSlerp	(	double	alpha,
		const GfQuath &	q0,
		const GfQuath &	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.
