Example 2 with Quaternion

    // Compute the cosine of the angle between the two vectors.
    // If the dot product is negative, slerp won't take
    // the shorter path. Note that v1 and -v1 are equivalent when
    // the negation is applied to all four components. Fix by
    // reversing one quaternion.
