+ * Cameras have a representation in the node graph and can be animated.

+ * by the node which corresponds to the camera. This allows for camera
+ * animations. For static cameras parameters like the 'look-at' or 'up' vectors

+ * be encoded in the node transformation. The following (pseudo)code sample 
+ * shows how to do it: <br><br>
+ * @code
+ * // Get the camera matrix for a camera at a specific time
+ * // if the node hierarchy for the camera does not contain
+ * // at least one animated node this is a static computation
+ * get-camera-matrix (node sceneRoot, camera cam) : matrix
+ * {
+ *    node   cnd = find-node-for-camera(cam)
+ *    matrix cmt = identity()
+ *
+ *    // as usual - get the absolute camera transformation for this frame
+ *    for each node nd in hierarchy from sceneRoot to cnd
+ *      matrix cur

+ *         cur = eval-animation(nd)
+ *      else cur = nd->mTransformation;
+ *      cmt = mult-matrices( cmt, cur )
+ *    end for
+ *
+ *    // now multiply with the camera's own local transform
+ *    cam = mult-matrices (cam, get-camera-matrix(cmt) )
+ * }
+ * @endcode
+ *
+ * @note some file formats (such as 3DS, ASE) export a "target point" -
+ * the point the camera is looking at (it can even be animated). Assimp
+ * writes the target point as a subnode of the camera's main node,
