float dot(const SbVec3f &v) const

Returns dot (inner) product of vector and another vector.

SbBool equals(const SbVec3f v, float tolerance) const

Equality comparison within given tolerance –the square of the length of the maximum distance between the two vectors.

SbVec3f getClosestAxis() const

Returns principal axis that is closest (based on maximum dot product) to this vector.
