[umen242]

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
like :

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 :

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 :

Video Card Vendor:    NVIDIA Corporation
Renderer:             GeForce 6200 TurboCache(TM)/PCI/SSE2
OpenGL Version:       2.1.2
GLU Version:          1.2.2.0 Microsoft Corporation

but i can't find it , can someone please tell me what are this constants ?

I guess you need GLU 1.3.
Windows comes with GLU 1.2, as you see in your output.
mesa3d comes with GLU 1.3 but you have to compile it yourself.
