I’m trying to tessellation a polygon non convex and i saw that i have to use this code:
gluBeginPolygon(tess);
gluTessVertex(tess, 100, 0);
gluTessVertex(tess, 100, 100);
gluTessVertex(tess, 150, 100);
gluTessVertex(tess, 150, 50);
gluTessVertex(tess, 200, 50);
gluTessVertex(tess, 200, 100);
gluTessVertex(tess, 250, 100);
gluTessVertex(tess, 250, 0);
gluEndPolygon(tess);
but it doesn’t work cause it tells me undeclared identifier… i saw that i must put gluNewTess but i don’t know how to write it for let it work…pls help me!!
