Detailed Description

OffScreen Mesa rendering window.

vtkOSOpenGLRenderWindow is a concrete implementation of the abstract class vtkOpenGLRenderWindow. vtkOSOpenGLRenderWindow interfaces to the OffScreen Mesa software implementation of the OpenGL library. The framebuffer resides on host memory. The framebuffer is the collection of logical buffers (color buffer(s), depth buffer, stencil buffer, accumulation buffer, multisample buffer) defining where the output of GL rendering is directed. Application programmers should normally use vtkRenderWindow instead of the OpenGL specific version.

Return 1 if this class is the same type of (or a subclass of) the named class.

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

Reimplemented from vtkOpenGLRenderWindow.

◆ PrintSelf()

void vtkOSOpenGLRenderWindow::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
virtual

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 vtkOpenGLRenderWindow.

◆ Start()

virtual void vtkOSOpenGLRenderWindow::Start ( void  )
virtual

Begin the rendering process.

Implements vtkRenderWindow.

◆ Frame()

virtual void vtkOSOpenGLRenderWindow::Frame ( void  )
virtual

End the rendering process and display the image.

Implements vtkRenderWindow.

◆ WindowInitialize()

virtual void vtkOSOpenGLRenderWindow::WindowInitialize ( void  )
virtual

Initialize the window for rendering.

◆ Initialize()

void vtkOSOpenGLRenderWindow::Initialize ( void  )
overridevirtual

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 from vtkOpenGLRenderWindow.

◆ Finalize()

virtual void vtkOSOpenGLRenderWindow::Finalize ( void  )
virtual

"Deinitialize" the rendering window.

This will shutdown all system-specific resources. After having called this, it should be possible to destroy a window that was used for a SetWindowId() call without any ill effects.

Implements vtkRenderWindow.

◆ SetFullScreen()

virtual void vtkOSOpenGLRenderWindow::SetFullScreen ( vtkTypeBool  )
virtual

Change the window to fill the entire screen.

Implements vtkRenderWindow.

virtual void vtkOSOpenGLRenderWindow::SetSize ( int  x,
int  y 
)
virtual

Specify the size of the rendering window in pixels.

Reimplemented from vtkOpenGLRenderWindow.

virtual void vtkOSOpenGLRenderWindow::SetSize ( int  a[2])
inlinevirtual

Set the size of the window in screen coordinates in pixels.

Get the current size of the screen in pixels.

Implements vtkWindow.

◆ GetPosition()

virtual int* vtkOSOpenGLRenderWindow::GetPosition ( )

Get the position in screen coordinates (pixels) of the window.

Reimplemented from vtkWindow.

◆ SetPosition() [1/2]

void vtkOSOpenGLRenderWindow::SetPosition ( int  x,

)
virtual

Move the window to a new position on the display.

Reimplemented from vtkWindow.

◆ SetPosition() [2/2]

void vtkOSOpenGLRenderWindow::SetPosition ( int  a[2])
inlinevirtual

Reimplemented from vtkWindow.

Definition at line 103 of file vtkOSOpenGLRenderWindow.h.

◆ SetStereoCapableWindow()

virtual void vtkOSOpenGLRenderWindow::SetStereoCapableWindow ( vtkTypeBool  capable)
virtual

Prescribe that the window be created in a stereo-capable mode.

This method must be called before the window is realized. This method overrides the superclass method since this class can actually check whether the window has been realized yet.

Reimplemented from vtkRenderWindow.

◆ MakeCurrent()

void vtkOSOpenGLRenderWindow::MakeCurrent ( )
virtual

Make this window the current OpenGL context.

Implements vtkRenderWindow.

◆ IsCurrent()

virtual

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

Implements vtkRenderWindow.

◆ SetForceMakeCurrent()

void vtkOSOpenGLRenderWindow::SetForceMakeCurrent ( )
virtual

If called, allow MakeCurrent() to skip cache-check when called.

MakeCurrent() reverts to original behavior of cache-checking on the next render.

Reimplemented from vtkRenderWindow.

◆ ReportCapabilities()

const char* vtkOSOpenGLRenderWindow::ReportCapabilities ( )
virtual

Get report of capabilities for the render window.
