    <desc>Returns a 3x4 rotation matrix around the axis given by the vector (<code>rx</code>, <code>ry</code>, <code>rz</code>) by <code>angle</code> degrees. It can be used as a transformation for <funclink>AttachMesh</funclink> or for the "PictureTransformation" or "MeshTransformation" properties (see <emlink href="definition/meshes.html#Picture">Meshes</emlink>).</desc>
    <examples>
      <example>
        <code><funclink>this</funclink>[&quot;PictureTransformation&quot;] = <funclink>Trans_Rotate</funclink>(20, 0, 1, 0);</code>
        <text>Rotates the picture graphics of the calling object by 20 degrees around the Y axis.</text>
