This article describes the data/samples/objects/gui_02.cpp sample.
The gui_02 sample demonstrates how to display the current scene on a virtual monitor created with the WidgetSpriteViewport and assigned to a GUI object, namely:
- Create the flat GUI object
- Create an instance of the WidgetSpriteViewport class and associate it with the camera
- Assign the created instance to the GUI object
- Set modelview and projection matrices for the associated camera and change them according to the time spent since the world loading. It will force the camera go round the objects in the scene.
