Constructor & Destructor Documentation

VRS::Alternative::Alternative	(	int	id = 1,
		double	intensity = 0.5
	)

The Alternative attribute specifies that shapes that are marked with it are rendered in a transparent way that absolutely prevents transparency artifacts. All shapes in the scene graph with Alternative attributes that hold the same ID (called a shape set in the following) are treated together. First, all shapes in the scene graph without Alternative attribute are rendered (opaque). Then, for each shape set, only the frontmost fragment is blended to the frame buffer (using the intensity of the corresponding Alternative attribute).
