public static void FrontFace(
	glFaceOrientation orientation
)

Public Shared Sub FrontFace ( 
	orientation As glFaceOrientation
)

public:
static void FrontFace(
	glFaceOrientation orientation
)

static member FrontFace : 
        orientation : glFaceOrientation -> unit 

Parameters

orientation

Type: OooglesglFaceOrientation
the orientation of front-facing polygons. Initial value is CounterClockwise.

The projection of a polygon to window coordinates is said to have clockwise winding if an imaginary object following the path from its first vertex, its second vertex, and so on, to its last vertex, and finally back to its first vertex, moves in a clockwise direction about the interior of the polygon. The polygon's winding is said to be counterclockwise if the imaginary object following the same path moves in a counterclockwise direction about the interior of the polygon. glFrontFace specifies whether polygons with clockwise winding in window coordinates, or counterclockwise winding in window coordinates, are taken to be front-facing. Passing CounterClockwise selects counterclockwise polygons as front-facing; Clockwise selects clockwise polygons as front-facing. By default, counterclockwise polygons are taken to be front-facing.
