NAME
gluBeginPolygon - delimit a polygon description
C SPECIFICATION
void gluBeginPolygon(GLUtesselator* tess);
C SPECIFICATION
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This command is obsolete and is provided for backward compatibility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().
EXAMPLE
A quadrilateral with a triangular hole in it can be described like
this:
gluBeginPolygon(tobj);
gluTessVertex(tobj, v1, v1);
gluTessVertex(tobj, v2, v2);
gluTessVertex(tobj, v3, v3);
gluTessVertex(tobj, v4, v4);
gluNextContour(tobj, GLU_INTERIOR);
gluTessVertex(tobj, v5, v5);
gluTessVertex(tobj, v6, v6);
gluTessVertex(tobj, v7, v7);
gluEndPolygon(tobj);
