Examples of com.ardor3d.math.Quaternion.fromAxes()

com.ardor3d.math.Quaternion.fromAxes()
Updates this quaternion to represent a rotation formed by the given three axes. These axes are assumed to be orthogonal and no error checking is applied. It is the user's job to insure that the three axes being provided indeed represent a proper right handed coordinate system. @param xAxis vector representing the x-axis of the coordinate system. @param yAxis vector representing the y-axis of the coordinate system. @param zAxis vector representing the z-axis of the coordinate system. @return this quaternion for chaining

        // quaternion is computed, then normalized to unit length. The result is
        // the slerp of the two input quaternions with t-value of 1/2. The
        // result is converted back to a rotation matrix and its columns are
        // selected as the merged box axes.
        final Quaternion kQ0 = Quaternion.fetchTempInstance(), kQ1 = Quaternion.fetchTempInstance();
        kQ0.fromAxes(rkBox0._xAxis, rkBox0._yAxis, rkBox0._zAxis);
        kQ1.fromAxes(rkBox1._xAxis, rkBox1._yAxis, rkBox1._zAxis);


        if (kQ0.dot(kQ1) < 0.0) {
            kQ1.multiplyLocal(-1.0);
        }
