when i stalled VC 6.0,i checked my glu.h and i can’t find gluUnProject4,why?,how to handle that?
gluUnProject4 was introduced in GLU 1.3, but Windows ships with GLU 1.2, so it is not available on the Windows platform by default. You could, however, try to compile a new version of GLU from Mesa if you really need that function.
