Function Documentation

◆ GfDot()

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

Return the dot (inner) product of two quaternions.

Definition at line 280 of file quath.h.

◆ 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.
