glEdgeFlag(3G)		       OpenGL Reference			glEdgeFlag(3G)


NAME    [Toc]    [Back]

     glEdgeFlag, glEdgeFlagv - flag edges as either boundary or	nonboundary

C SPECIFICATION    [Toc]    [Back]

     void glEdgeFlag( GLboolean	flag )

PARAMETERS    [Toc]    [Back]

     flag  Specifies the current edge flag value, either GL_TRUE or GL_FALSE.
	   The initial value is	GL_TRUE.

C SPECIFICATION    [Toc]    [Back]

     void glEdgeFlagv( const GLboolean *flag )

PARAMETERS    [Toc]    [Back]

     flag Specifies a pointer to an array that contains	a single boolean
	  element, which replaces the current edge flag	value.

DESCRIPTION    [Toc]    [Back]

     Each vertex of a polygon, separate	triangle, or separate quadrilateral
     specified between a glBegin/glEnd pair is marked as the start of either a
     boundary or nonboundary edge.  If the current edge	flag is	true when the
     vertex is specified, the vertex is	marked as the start of a boundary
     edge.  Otherwise, the vertex is marked as the start of a nonboundary
     edge.  glEdgeFlag sets the	edge flag bit to GL_TRUE if flag is GL_TRUE,
     and to GL_FALSE otherwise.

     The vertices of connected triangles and connected quadrilaterals are
     always marked as boundary,	regardless of the value	of the edge flag.

     Boundary and nonboundary edge flags on vertices are significant only if
     GL_POLYGON_MODE is	set to GL_POINT	or GL_LINE.  See glPolygonMode.

NOTES    [Toc]    [Back]

     The current edge flag can be updated at any time.	In particular,
     glEdgeFlag	can be called between a	call to	glBegin	and the	corresponding
     call to glEnd.

ASSOCIATED GETS    [Toc]    [Back]

     glGet with	argument GL_EDGE_FLAG
