Matrix4d.rotate

Apply a rotation transformation, rotating the given radians about the specified axis, to this matrix. <p> When used with a right-handed coordinate system, the produced rotation will rotate a vector counter-clockwise around the rotation axis, when viewing along the negative axis direction towards the origin. When used with a left-handed coordinate system, the rotation is clockwise. <p> If <code>M</code> is <code>this</code> matrix and <code>A</code> the rotation matrix obtained from the given angle and axis, then the new matrix will be <code>M * A</code>. So when transforming a vector <code>v</code> with the new matrix by using <code>M * A * v</code>, the axis-angle rotation will be applied first! <p> In order to set the matrix to a rotation transformation without post-multiplying, use {@link #rotation(double, Vector3d)}. <p> Reference: <a href="http://en.wikipedia.org/wiki/Rotation_matrix#Axis_and_angle">http://en.wikipedia.org</a>
