◆ SetImmediateModeDrawToFront()

Standard_Boolean OpenGl_View::SetImmediateModeDrawToFront ( const Standard_Boolean  theDrawToFrontBuffer)
overridevirtual
Parameters
theDrawToFrontBufferAdvanced option to modify rendering mode:
  1. TRUE. Drawing immediate mode structures directly to the front buffer over the scene image. Fast, so preferred for interactive work (used by default). However these extra drawings will be missed in image dump since it is performed from back buffer. Notice that since no pre-buffering used the V-Sync will be ignored and rendering could be seen in run-time (in case of slow hardware) and/or tearing may appear. So this is strongly recommended to draw only simple (fast) structures.
  2. FALSE. Drawing immediate mode structures to the back buffer. The complete scene is redrawn first, so this mode is slower if scene contains complex data and/or V-Sync is turned on. But it works in any case and is especially useful for view dump because the dump image is read from the back buffer.
Returns
previous mode.
