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.

◆ SetFrameBlitMode()

virtual void vtkOpenGLRenderWindow::SetFrameBlitMode ( FrameBlitModes  )
virtual

SetGet how to handle blits at the end of a Frame() call.

Only happens when SwapBuffers is true.

The “blit” operation means copying something (pixels) from one region in memory to another. This is a common OpenGL operation: check out the glBlitFramebuffer OpenGL method. VTK OpenGL rasterizes 3D/2D geometry into color/depth attachments of an in-memory framebuffer: in the graphics world, this is called offscreen rendering.

The FrameBlitMode tells VTK where to copy the offscreen buffer. Either the default hardware framebuffer or the currently bound framebuffer. Here are the available modes:

  • BlitToHardware: This mode blits to the default framebuffer managed by platform(Win32/X/Cocoa) render windows. This is the default mode when VTK is used through one of the platform render windows (with vtkRenderWindow).
  • BlitToCurrent: This mode blits to the currently bound framebuffer. It is useful when an external framebuffer is bound just before the vtkRenderWindow::Frame() call. You’ll need this when integrating VTK with other UI frameworks because these UI frameworks create/have their own framebuffers. This only blits the color buffer.
  • BlitToCurrentWithDepth: Almost the same as BlitToCurrent, but this mode also blits the depth buffer.
  • NoBlit: no blit. The GUI or external code will handle the blit.
