Add an update operation.

virtual void osgViewer::ViewerBase::advance ( double  simulationTime = USE_REFERENCE_TIME)
pure virtual

Implemented in osgViewer::CompositeViewer, and osgViewer::Viewer.

bool osgViewer::ViewerBase::areThreadsRunning ( ) const
inline

Return true if viewer threads are running.

Definition at line 86 of file ViewerBase.h.

virtual bool osgViewer::ViewerBase::checkEvents ( )
pure virtual

check to see if events have been received, return true if events are now available.

Implemented in osgViewer::CompositeViewer, and osgViewer::Viewer.

virtual bool osgViewer::ViewerBase::checkNeedToDoFrame ( )

Execute a main frame loop. Equivalent to while (!viewer.done()) viewer.frame(); Also calls realize() if the viewer is not already realized, and installs trackball manipulator if one is not already assigned.

Reimplemented in osgViewer::CompositeViewer, and osgViewer::Viewer.

void osgViewer::ViewerBase::setDone ( bool  done)
inline

Set the done flag to signal the viewer's work is done and should exit the frame loop.

Definition at line 121 of file ViewerBase.h.

void osgViewer::ViewerBase::setEndBarrierOperation ( osg::BarrierOperation::PreBlockOp  op)

Set the end barrier operation. op may be one of GL_FLUSH, GL_FINISH, or NO_OPERATION. NO_OPERATION is the default. Per BarrierOperation::operator()(), a glFlush() command, glFinish() command, or no additional OpenGL command will be issued before entering the end barrier.

void osgViewer::ViewerBase::setEndBarrierPosition ( BarrierPosition  bp)

Set the position of the end barrier. AfterSwapBuffers may result in slightly higher framerates, but may lead to inconsistent swapping between different windows. BeforeSwapBuffers may lead to slightly lower framerate, but improve consistency in timing of swap buffers, especially important if you are likely to consistently break frame.

void osgViewer::ViewerBase::setEventVisitor ( osgGA::EventVisitor *  eventVisitor)
inline

Set the EventVisitor.

Definition at line 127 of file ViewerBase.h.

void osgViewer::ViewerBase::setIncrementalCompileOperation ( osgUtil::IncrementalCompileOperation *  ico)

Set the incremental compile operation. Used to manage the OpenGL object compilation and merging of subgraphs in a way that avoids overloading the rendering of frame with too many new objects in one frame.

void osgViewer::ViewerBase::setKeyEventSetsDone ( int  key)
inline

Set the key event that the viewer checks on each frame to see if the viewer's done flag should be set to signal end of viewers main loop. Default value is Escape (osgGA::GUIEVentAdapter::KEY_Escape). Setting to 0 switches off the feature.

Definition at line 139 of file ViewerBase.h.

void osgViewer::ViewerBase::setQuitEventSetsDone ( bool  flag)
inline

if the flag is true, the viewer set its done flag when a QUIT_APPLICATION is received, false disables this feature

Definition at line 145 of file ViewerBase.h.

void osgViewer::ViewerBase::setRealizeOperation ( osg::Operation *  op)
inline

Set the graphics operation to call on realization of the viewers graphics windows.

Definition at line 191 of file ViewerBase.h.

void osgViewer::ViewerBase::setReleaseContextAtEndOfFrameHint ( bool  hint)
inline

Hint to tell the renderingTraversals() method whether to call releaseContext() on the last context that was made current by the thread calling renderingTraverals(). Note, when running multi-threaded viewer no threads will be made current or release current. Setting this hint to false can enable the frame loop to be lazy about calling makeCurrent and releaseContext on each new frame, helping performance. However, if you frame loop is managing multiple graphics context all from the main frame thread then this hint must be left on, otherwise the wrong context could be left active, introducing errors in rendering.

inline

Definition at line 212 of file ViewerBase.h.
