NAME
gluBeginPolygon, gluEndPolygon
- delimit a polygon description
C SPECIFICATION
void
gluBeginPolygon(
GLUtesselator*
tess )
void gluEndPolygon(
GLUtesselator* tess )
delim $$
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This command is obsolete and is provided for backward compatibility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);
