+===============================================================
+Controll:
+left mouse - rotate
+right mouse - move
+scroll - zoom
+space - reset view
+L - set light to current position
+esc - close
+
+using the X, Y, Z buttons you can activate/deactivate the rotating directions.
+
+tipp: do round movement to rotate the object in z-direction, when all directions are acitvated
+
+textures marked with a '*' couldn't be open.
