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 ?
