GLUTESSENDPOLYGON(3G) GLUTESSENDPOLYGON(3G)NAMEgluTessEndPolygon - delimit a polygon descriptionC SPECIFICATIONvoid gluTessEndPolygon( GLUtesselator* tess )PARAMETERStess Specifies the tessellation object (created with gluNewTess).DESCRIPTIONgluTessBeginPolygon and gluTessEndPolygon delimit the definition of a convex, concave or self-intersecting polygon. Within each gluTessBeginPolygon/gluTessEndPolygon pair, there must be one or more calls to gluTessBeginContour/gluTessEndContour. Within each contour, there are 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, gluTessBeginContour and gluTessEndContour reference pages for more details. Once gluTessEndPolygon is called, the polygon is tessellated, and the resulting triangles are described through callbacks. See gluTessCallback for descriptions of the callback functions.EXAMPLEA quadrilateral with a triangular hole in it can be described like this: gluTessBeginPolygon(tobj, NULL); gluTessBeginContour(tobj); gluTessVertex(tobj, v1, v1); gluTessVertex(tobj, v2, v2); gluTessVertex(tobj, v3, v3); gluTessVertex(tobj, v4, v4); gluTessEndContour(tobj); gluTessBeginContour(tobj); gluTessVertex(tobj, v5, v5); gluTessVertex(tobj, v6, v6); gluTessVertex(tobj, v7, v7); gluTessEndContour(tobj); gluTessEndPolygon(tobj); In the above example the pointers, v1 through v7, should point to different addresses, since the values stored at these addresses will not be read by the tesselator until gluTessEndPolygon is called.SEE ALSOgluNewTess(3G), gluTessBeginContour(3G), gluTessVertex(3G), gluTessCallback(3G), gluTessProperty(3G), gluTessNormal(3G), gluTessBeginPolygon(3G) GLUTESSENDPOLYGON(3G)
