Graphic3d_AspectLine3d() [1/2]

Graphic3d_AspectLine3d::Graphic3d_AspectLine3d

(

)

Creates a context table for line primitives defined with the following default values:

Color = Quantity_NOC_YELLOW; Type = Aspect_TOL_SOLID; Width = 1.0;

Graphic3d_AspectLine3d() [2/2]

Graphic3d_AspectLine3d::Graphic3d_AspectLine3d	(	const Quantity_Color &	theColor,
		Aspect_TypeOfLine	theType,
		Standard_Real	theWidth
	)

Creates a context table for line primitives defined with the specified values. Warning: theWidth is the "line width scale factor". The nominal line width is 1 pixel. The width of the line is determined by applying the line width scale factor to this nominal line width. The supported line widths vary by 1-pixel units.
