+source code: https://git.rwth-aachen.de/carstenf/OpenGL/tree/master/QtMeshViewer
+
+===============================================================
+Controll:
+left mouse - rotate
+right mouse - move
+scroll - zoom
+space - reset view
++/- - adjust zoom speed
+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.

-- cloth not working correctly
-- optional display bones, shadow, collision,...
-- integrate into a software:
--> gui open file ( + drag and drop),
--> list all msh under a directory,
--> display shadows,
--> display colisions,
--> lights,
--> handle render flags,
-
