class AspectMarker3d from Graphic3d inherits AspectMarker from Aspect

	---Version:

	---Purpose: Creates and updates an attribute group for
	--	    marker type primitives. This group contains the type
	--	    of marker, its colour, and its scale factor.
	---Keywords: Marker, Color, Scale, Type

	---Warning:

	--	    Colour		: YELLOW
	--	    Scale factor	: 1.0

-- Purpose	:	Declaration of context-specific variables
--			for drawing 3d markers.
--
-- Reminder	:	A context for drawing 3d markers inherits:
--			- the colour
--			- the type of marker
--			- the scale factor
--			defined by AspectMarker.
