Detailed Description

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

This class extends RenderArea to add mouse and keyboard interactions.

Definition at line 21 of file RenderAreaInteractive.h.

Member Enumeration Documentation

◆ ClippingPlanesAdjustMode

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.

Constructor & Destructor Documentation

◆ RenderAreaInteractive()

RenderAreaInteractive::RenderAreaInteractive ( QWidget *  parent)

This constructor initializes the QOpenGLWidget using the default QSurfaceFormat.

◆ ~RenderAreaInteractive()

virtual RenderAreaInteractive::~RenderAreaInteractive ( )
virtual

Destructor.

Member Function Documentation

◆ activateStereo()

virtual void RenderAreaInteractive::activateStereo ( bool  activated)
virtual

Activate/Deactivate stereo.

Reimplemented from RenderArea.

◆ getClippingPlanesAdjustMode()

ClippingPlanesAdjustMode RenderAreaInteractive::getClippingPlanesAdjustMode ( )

Get the camera clipping planes adjustment mode.

◆ getInteractiveMode()

virtual SoDEPRECATED SoInteractiveComplexity::InteractiveMode RenderAreaInteractive::getInteractiveMode ( ) const
virtual

Gets the current interactive mode.

Implements SiRenderAreaInteractive.

◆ getRootSceneGraph()

SoDEPRECATED SceneInteractor * RenderAreaInteractive::getRootSceneGraph ( ) const

Return the root of the scene graph.

◆ getSceneInteractor()

virtual SceneInteractor * RenderAreaInteractive::getSceneInteractor ( ) const
virtual

Return the root of the scene graph.

Reimplemented in RenderAreaOrbiter, and RenderAreaExaminer.

◆ isStereoSupported()

virtual bool RenderAreaInteractive::isStereoSupported ( ) const
virtual

Returns true if stereo can be activated.

◆ processEvent()

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

◆ processEvents()

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

◆ setClippingPlanesAdjustMode()

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.

◆ setInteractiveMode()

SoDEPRECATED void RenderAreaInteractive::setInteractiveMode ( SoInteractiveComplexity::InteractiveMode  mode)
virtual

Sets the current interactive mode.

Implements SiRenderAreaInteractive.

◆ setSceneGraph()

virtual void RenderAreaInteractive::setSceneGraph ( SoNode sceneGraph)
virtual

Sets the scene graph to render.

Reimplemented from RenderArea.

◆ setStereoCameraBalance()

void RenderAreaInteractive::setStereoCameraBalance ( float  balance)

Set the stereo balance.

◆ setStereoCameraOffset()

void RenderAreaInteractive::setStereoCameraOffset ( float  offset)

Set the stereo offset.

◆ viewAll()

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.

◆ viewAxis()

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.
