    <desc>Multiplies two or more 3x4 transformation matrices in the given order. This way the effects of more than one transformation can be combined. The result 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_Mul</funclink>(<funclink>Trans_Translate</funclink>(7000), <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 and afterwards displaces it by 7 units into Z direction towards the camera.</text>
