Changeset 7966 for code/branches/usability/src/orxonox/CameraManager.cc

Message:

some changes related to camera switching:

• added ViewportEventListener (currently only listens to camera changes in a viewport)
• Shader now correctly updates its visibility if the camera changes the scene
• (the same lines of code also fix the weird Ogre behavior which was originally fixed in CameraManager)
• GraphicsManager also updates the GUIManager's camera
• if all cameras are destroyed, CameraManager now officially switches to NULL camera
