Function Documentation

◆ GfDot()

double GfDot ( const GfQuatd q1,
const GfQuatd q2 
)
inline

Return the dot (inner) product of two quaternions.

Definition at line 262 of file quatd.h.

◆ GfSlerp()

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.
