# gluTessBeginContour

delimit a contour description

## C Specification

                    void gluTessBeginContour
                    GLUtesselator* tess

## C Specification

                    void gluTessEndContour
                    GLUtesselator* tess

## Parameters

`tess`

  Specifies the tessellation object (created with gluNewTess).

## Description

`gluTessBeginContour` and gluTessEndContour 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.
