Detailed Description

OpenGL rendering window.

vtkOpenGLRenderWindow is a concrete implementation of the abstract class vtkRenderWindow. vtkOpenGLRenderer interfaces to the OpenGL graphics library. Application programmers should normally use vtkRenderWindow instead of the OpenGL specific version.

inline

Return a message profiding additional details about the results of calling SupportsOpenGL() This can be used to retrieve more specifics about what failed.

Definition at line 336 of file vtkOpenGLRenderWindow.h.

Create and bind offscreen rendering buffers without destroying the current OpenGL context.

This allows to temporary switch to offscreen rendering (ie. to make a screenshot even if the window is hidden). Return if the creation was successful (1) or not (0). Note: This function requires that the device supports OpenGL framebuffer extension. The function has no effect if OffScreenRendering is ON.

Reimplemented from vtkRenderWindow.

bool vtkOpenGLRenderWindow::GetUseOffScreenBuffers ( )

Reimplemented in vtkOpenVRRenderWindow, vtkWin32OpenGLRenderWindow, vtkOSOpenGLRenderWindow, and vtkXOpenGLRenderWindow.

virtual void vtkOpenGLRenderWindow::Initialize ( void   )
inlinevirtual

Initialize the rendering window.

This will setup all system-specific resources. This method and Finalize() must be symmetric and it should be possible to call them multiple times, even changing WindowId in-between. This is what WindowRemap does.

Reimplemented in vtkOpenVRRenderWindow, vtkCocoaRenderWindow, vtkIOSRenderWindow, vtkEGLRenderWindow, vtkOSOpenGLRenderWindow, vtkXOpenGLRenderWindow, and vtkWin32OpenGLRenderWindow.

virtual void vtkOpenGLRenderWindow::PushContext ( )
inlinevirtual

Ability to push and pop this window's context as the current context.

The idea being to if needed make this window's context current and when done releasing resources restore the prior context. The default implementation here is only meant as a backup for subclasses that lack a proper implementation.

Reimplemented in vtkCocoaRenderWindow, vtkXOpenGLRenderWindow, and vtkWin32OpenGLRenderWindow.

Definition at line 397 of file vtkOpenGLRenderWindow.h.

virtual void vtkOpenGLRenderWindow::PopContext ( )

bool vtkOpenGLRenderWindow::InitializeFromCurrentContext ( )
overridevirtual

Initialize the render window from the information associated with the currently activated OpenGL context.

Reimplemented from vtkRenderWindow.

Reimplemented in vtkXOpenGLRenderWindow, and vtkWin32OpenGLRenderWindow.

virtual unsigned int vtkOpenGLRenderWindow::GetDefaultFrameBufferId ( )
virtual

Returns the id for the frame buffer object, if any, used by the render window in which the window does all its rendering.

This may be 0, in which case the render window is rendering to the default OpenGL render buffers.

Returns
the name (or id) of the frame buffer object to render to.
virtual bool vtkOpenGLRenderWindow::SetSwapControl ( int  )
inlinevirtual

Set the number of vertical syncs required between frames.

A value of 0 means swap buffers as quickly as possible regardless of the vertical refresh. A value of 1 means swap buffers in sync with the vertical refresh to eliminate tearing. A value of -1 means use a value of 1 unless we missed a frame in which case swap immediately. Returns true if the call succeeded.

Reimplemented in vtkXOpenGLRenderWindow, and vtkWin32OpenGLRenderWindow.
