gluTessBeginContour

Purpose

Delimits a contour description.

Library

C bindings library: libGL.a

C Syntax

void gluTessBeginContour(
    GLUtesselator*	 tess)
void gluTessEndContour(
    GLUtesselator*	 tess)

Parameters

tess
Specifies the tessellation object (created with gluNewTess).

Description

The gluTessBeginContour subroutine and gluTessEndContour subroutine delimit the definition of a polygon contour. Within each gluTessBeginContour/gluTessEndContour pair, there can be zero or more calls to gluTessVertex. The vertices specify a closed contour (the last vertex of each contour is automatically linked to the first). See the gluTessVertex reference page for more details. gluTessBeginContour can only be called between gluTessBeginPolygon and gluTessEndPolygon.
