Question about gluUnProject4(...)


I’m working with Borland C++ Builder 5
I guess it is using OpenGL 1.1 version

Does it has the function :
gluUnProject4(…) ??

In help I found only gluUnProject(…)

If my version does not have gluUnProject4,
can I use gluUnProject instead ? (because my
depth range is not the default [0,1],I use different.)

gluUnproject4 is in glu 1.3
If you don’t have it already, you can download from

The lib is for VC++ so I think you need a tool like implib to import to the Borland format.
