Detailed Description

Scene is the main visualization widget that shows the graphical Representation 's. To do this, the class Scene must be a child of the MainControl. Because the MainControl is also the main application object a Scene must be created with the pointer to the MainControl as parent widget.
Scene is capable of stereo 3D view with shutter glasses and CRT monitors. This only works, if the OpenGL-driver supports this. NVIDIA cards need a Quad buffer, like they are used in the "Quad" cards. For other NVIDIA cards, you can try the tool "Rivatuner", which tries to enable this feature for cards, which natively dont support this. To enter and leave the stereo mode, press ALT-Y. If your OpenGL doesnt support the stereo view, you will see an error message in the message bar at the bottom of the main window.

The Scene has tree different mouse modi:

To change between the first two modi, there is a menu entry with checkboxes in the main menu bar of the application.
In Picking mode, left mouse button selects composites and right mouse button deselects. There are two ways to (de-)select: Either click on single items, or draw a selection rectangle by keeping the mouse button pressed and moving the mouse. Users with only one mouse button can use the SHIFT button, while pressing the mouse button to deselect.
In Rotate mode, left mouse button rotates, mid mouse button zooms in and out and right button moves the view. Users with only one mouse button can use the SHIFT / CONTROL button, while pressing the mouse button.
The eye distance change mode is only available in the stereo view mode. Here a user can press the ALT-button and move the mouse left or right to adjust the eye distance to their desired value.
Its possible to add new modi, to do so, derive a new class from Scene and overload the mouse*Event methods.

Furthermore, users can create modified versions of the GLRenderer and pass them to the Scene with the method setGLRenderer.

Member Enumeration Documentation

Different Mouse Mode actions.

Enumerator:
TRANSLATE_ACTION 
ZOOM_ACTION 
ROTATE_ACTION 
ROTATE_CLOCKWISE_ACTION 

Definition at line 158 of file scene.h.

Predefined constants for the mode types Add new enums members in derived classes, for new modi. If you add new modi in this class, you have to add them in front of the PICKING__MODE entry.

Enumerator:
ROTATE__MODE 

Default value.

MOVE__MODE 

Move mode.

PICKING__MODE 

Picking mode.

Definition at line 143 of file scene.h.

Scene may hold several windows for different renering modes. If you need to retrieve a particular window, use this enum together with Scene::getWindow() to get a reference to it.

Enumerator:
CONTROL_WINDOW 

Main window that is always being displayed directly in the QT main interface.

LEFT_EYE_WINDOW 

Window into which left eye should be rendered. Indicates same window as CONTROL_WINDOW if no stereo is running.

RIGHT_EYE_WINDOW 

Window into which right eye should be renderer. Indicates same window as CONTROL_WINDOW if no stereo is running.
