beginner opengl where is GLU_EXT_object_space_tess ? or GLU_NURBS_ERROR?
im beginner , i have old opengl code that i want to port from mac to windows
in the code i see it is using some constants that i guess dealing with NURBS
Code :GLU_EXT_object_space_tess GLU_EXT_nurbs_tessellator GLU_NURBS_ERROR
and it gives me compilation error that it is : undeclared identifier . i tried to search in the header code in my source (this is what i have in my Microsoft Platform SDK for Windows Server 2003 R2\Include\gl\ dir :
Code :GL.h GLAux.h GLU.h freeglut.h freeglut_ext.h freeglut_std.h glew.h glut.h glxew.h wglew.h
according to the DoctorGL util im using :
Code :Video Card Vendor: NVIDIA Corporation Renderer: GeForce 6200 TurboCache(TM)/PCI/SSE2 OpenGL Version: 2.1.2 GLU Version: 184.108.40.206 Microsoft Corporation
but i can't find it , can someone please tell me what are this constants ?
