Detailed Description

Class to render an OpenInventor scene in a Qt OpenGL window.

This class extends RenderArea to add mouse and keyboard interactions.


Member Enumeration Documentation

Camera clipping planes adjustment mode.

When adjustment mode is set to AUTO, the camera near and far planes are dynamically adjusted to be as tight as possible (least amount of stuff is clipped) before each render traversal. When adjustment mode is set to MANUAL, the user is expected to manually set the camera near and far planes.

Enumerator:
AUTO 
MANUAL 

Constructor & Destructor Documentation

RenderAreaInteractive::RenderAreaInteractive ( QWidget *  parent  ) 

This constructor initializes the QOpenGLWidget using the default QSurfaceFormat.

virtual RenderAreaInteractive::~RenderAreaInteractive (  )  [virtual]

Destructor.


Member Function Documentation

virtual void RenderAreaInteractive::activateStereo ( bool  activated  )  [virtual]

Activate/Deactivate stereo.

Reimplemented from RenderArea.

ClippingPlanesAdjustMode RenderAreaInteractive::getClippingPlanesAdjustMode (  ) 

Get the camera clipping planes adjustment mode.

virtual SoInteractiveComplexity::InteractiveMode RenderAreaInteractive::getInteractiveMode (  )  const [virtual]

Gets the current interactive mode.

Implements SiRenderAreaInteractive.

SoDEPRECATED SceneInteractor* RenderAreaInteractive::getRootSceneGraph (  )  const

Return the root of the scene graph.

Deprecated:

Deprecated since Open Inventor 10500
Use getSceneInteractor() method instead.
virtual SceneInteractor* RenderAreaInteractive::getSceneInteractor (  )  const [virtual]

Return the root of the scene graph.

Reimplemented in RenderAreaExaminer, and RenderAreaOrbiter.

virtual bool RenderAreaInteractive::isStereoSupported (  )  const [virtual]

Returns true if stereo can be activated.

virtual SbBool RenderAreaInteractive::processEvent ( const SoEvent event  )  [virtual]

Processes the passed event to the scene graph managed here.

Returns TRUE if the event was handled by a node.

NOTES

virtual SbBool RenderAreaInteractive::processEvents ( const std::vector< const SoEvent * > &  eventList  )  [virtual]

Processes the passed event to the scene graph managed here.

Returns TRUE if at least one event was handled by a node.

NOTES

void RenderAreaInteractive::setClippingPlanesAdjustMode ( ClippingPlanesAdjustMode  mode  ) 

Set the camera clipping planes adjustment mode.

When adjustment mode is set to AUTO, the camera near and far planes are dynamically adjusted to be as tight as possible (least amount of stuff is clipped) before each render traversal. When adjustment mode is set to MANUAL, the user is expected to manually set those planes. Updating clipping planes after a camera move is not enough, if a dragger or a rendered shape is moved, they can disappear or become partially clipped. Default is AUTO.

void RenderAreaInteractive::setInteractiveMode ( SoInteractiveComplexity::InteractiveMode  mode  )  [virtual]

Sets the current interactive mode.

Implements SiRenderAreaInteractive.

virtual void RenderAreaInteractive::setSceneGraph ( SoNode sceneGraph  )  [virtual]

Sets the scene graph to render.

Reimplemented from RenderArea.

void RenderAreaInteractive::setStereoCameraBalance ( float  balance  ) 

Set the stereo balance.

void RenderAreaInteractive::setStereoCameraOffset ( float  offset  ) 

Set the stereo offset.

virtual void RenderAreaInteractive::viewAll ( const SbViewportRegion viewport  )  [virtual]

Move the camera to view the scene defined by the given path.

Equivalent to calling the SoCamera method viewAll(). Camera position is changed, but not orientation.

virtual void RenderAreaInteractive::viewAxis ( const SbVec3f direction,
const SbVec3f up 
) [virtual]

Moves the camera to be aligned with the given direction vector while keeping the "up" direction of the camera parallel to the specified up vector.
