    def _build_transform(
        self, x: float, y: float, z: float, a: float, b: float, c: float
    ) -> gp_Trsf:

        rv = gp_Trsf()
        m = a ** 2 + b ** 2 + c ** 2

        rv.SetRotation(
            gp_Quaternion(
                2 * a / (m + 1), 2 * b / (m + 1), 2 * c / (m + 1), (1 - m) / (m + 1),
            )
        )

        rv.SetTranslationPart(gp_Vec(x, y, z))

        return rv

Example #2

def tq_to_loc(t, q):
    T = gp_Trsf()
    Q = gp_Quaternion(*q)
    V = gp_Vec(*t)
    T.SetTransformation(Q, V)
    return TopLoc_Location(T)
