NAME
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This command is obsolete and is provided for backward compatibility only.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 fol- lowed 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);
