Constructor & Destructor Documentation

OpenGl_Annotation()

GEOM_Annotation::OpenGl_Annotation::OpenGl_Annotation	(	GEOM_Annotation *	theAnnotation,
		const Standard_Integer	theTextHeight,
		const OpenGl_GraphicDriver *	theDriver
	)

Some of the input properties are assigned by reference for dynamic draw (it is not likely that GL element will ever outlive the interactive object).

Parameters

theAnnotation	[in] the instance of interactive presentation class.
theTextHeight	[in] the height of the text label.
theDriver	[in] the instance of graphical driver required for initialization.
