virtual void vtkOpenGLTexture::PostRender ( vtkRenderer *  )

virtual

Cleans up after the texture rendering to restore the state of the graphics context.

Reimplemented from vtkTexture.

void vtkOpenGLTexture::ReleaseGraphicsResources ( vtkWindow *  )

virtual

Release any graphics resources that are being consumed by this texture. The parameter window could be used to determine which graphic resources to release. Using the same texture object in multiple render windows is NOT currently supported.

Reimplemented from vtkTexture.

virtual long vtkOpenGLTexture::GetIndex ( )
