gluBeginPolygon

gluBeginPolygon, gluEndPolygon: delimit a polygon description.

C Speciﬁcation

void gluBeginPolygon(

GLUtesselator* tess)

void gluEndPolygon(

GLUtesselator* tess)

Parameters

tess Speciﬁes the tessellation object (created with gluNewTess).

Description

gluBeginPolygon and gluEndPolygon delimit the deﬁnition of a nonconvex polygon. To

deﬁne such a polygon, ﬁrst call gluBeginPolygon. Then deﬁne the contours of the polygon

by calling gluTessVertex for each vertex and gluNextContour to start each new contour.

Finally, call gluEndPolygon to signal the end of the deﬁnition. See the gluTessVertex and

gluNextContour reference pages for more details.

Once gluEndPolygon is called, the polygon is tessellated, and the resulting triangles are

described through callbacks. See gluTessCallback for descriptions of the callback

functions.

Notes

This command is obsolete and is provided for backward compatibility only. Calls to

gluBeginPolygon are mapped to gluTessBeginPolygon followed by gluTessBeginContour.

Calls to gluEndPolygon are mapped to gluTessEndContour followed by

gluTessEndPolygon.
