Detailed Description

OpenGL render window that allows using an external window to render vtk objects.

vtkExternalOpenGLRenderWindow is a concrete implementation of the abstract class vtkRenderWindow. vtkExternalOpenGLRenderer interfaces to the OpenGL graphics library.

This class extends vtkGenericOpenGLRenderWindow to allow sharing the same OpenGL context by various visualization applications. Basically, this class prevents VTK from creating a new OpenGL context. Thus, it requires that an OpenGL context be initialized before Render is called.

See also

Render()

It is a generic implementation; this window is platform agnostic. However, the application user must explicitly make sure the window size is synchronized when the external application window/viewport resizes.

See also

SetSize()

It has the same requirements as the vtkGenericOpenGLRenderWindow, whereby, one must register an observer for WindowMakeCurrentEvent, WindowIsCurrentEvent and WindowFrameEvent.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

PrintSelf()

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

Start()

void vtkExternalOpenGLRenderWindow::Start ( )

overridevirtual

Begin the rendering process using the existing context.

Reimplemented from vtkRenderWindow.

IsCurrent()

bool vtkExternalOpenGLRenderWindow::IsCurrent ( )

overridevirtual

Tells if this window is the current graphics context for the calling thread.

Reimplemented from vtkRenderWindow.

GetAutomaticWindowPositionAndResize()

virtual int vtkExternalOpenGLRenderWindow::GetAutomaticWindowPositionAndResize ( )

virtual

Turn on/off a flag which enables/disables automatic positioning and resizing of the render window.

By default, vtkExternalOpenGLRenderWindow queries the viewport position and size (glViewport) from the OpenGL state and uses it to resize itself. However, in special circumstances this feature is undesirable. One such circumstance may be to avoid performance penalty of querying OpenGL state variables. So the following boolean is provided to disable automatic window resize. (Turn AutomaticWindowPositionAndResize off if you do not want the viewport to be queried from the OpenGL state.)

SetAutomaticWindowPositionAndResize()

virtual void vtkExternalOpenGLRenderWindow::SetAutomaticWindowPositionAndResize ( int  )

virtual

Turn on/off a flag which enables/disables automatic positioning and resizing of the render window.

By default, vtkExternalOpenGLRenderWindow queries the viewport position and size (glViewport) from the OpenGL state and uses it to resize itself. However, in special circumstances this feature is undesirable. One such circumstance may be to avoid performance penalty of querying OpenGL state variables. So the following boolean is provided to disable automatic window resize. (Turn AutomaticWindowPositionAndResize off if you do not want the viewport to be queried from the OpenGL state.)

AutomaticWindowPositionAndResizeOn()

virtual void vtkExternalOpenGLRenderWindow::AutomaticWindowPositionAndResizeOn ( )

virtual

Turn on/off a flag which enables/disables automatic positioning and resizing of the render window.

By default, vtkExternalOpenGLRenderWindow queries the viewport position and size (glViewport) from the OpenGL state and uses it to resize itself. However, in special circumstances this feature is undesirable. One such circumstance may be to avoid performance penalty of querying OpenGL state variables. So the following boolean is provided to disable automatic window resize. (Turn AutomaticWindowPositionAndResize off if you do not want the viewport to be queried from the OpenGL state.)

AutomaticWindowPositionAndResizeOff()

virtual void vtkExternalOpenGLRenderWindow::AutomaticWindowPositionAndResizeOff ( )

virtual

Turn on/off a flag which enables/disables automatic positioning and resizing of the render window.

By default, vtkExternalOpenGLRenderWindow queries the viewport position and size (glViewport) from the OpenGL state and uses it to resize itself. However, in special circumstances this feature is undesirable. One such circumstance may be to avoid performance penalty of querying OpenGL state variables. So the following boolean is provided to disable automatic window resize. (Turn AutomaticWindowPositionAndResize off if you do not want the viewport to be queried from the OpenGL state.)

GetUseExternalContent()

virtual bool vtkExternalOpenGLRenderWindow::GetUseExternalContent ( )

virtual

Turn on/off a flag which enables/disables using the content from an outside application.

When on the active read buffer is first blitted into VTK and becomes the starting point for VTK's rendering.

SetUseExternalContent()

virtual void vtkExternalOpenGLRenderWindow::SetUseExternalContent ( bool  )

virtual

Turn on/off a flag which enables/disables using the content from an outside application.

When on the active read buffer is first blitted into VTK and becomes the starting point for VTK's rendering.

UseExternalContentOn()

virtual void vtkExternalOpenGLRenderWindow::UseExternalContentOn ( )

virtual

Turn on/off a flag which enables/disables using the content from an outside application.

When on the active read buffer is first blitted into VTK and becomes the starting point for VTK's rendering.

UseExternalContentOff()

virtual void vtkExternalOpenGLRenderWindow::UseExternalContentOff ( )

virtual

Turn on/off a flag which enables/disables using the content from an outside application.

When on the active read buffer is first blitted into VTK and becomes the starting point for VTK's rendering.
