I was just compiling the sample code from the opengl superbible , when i got “‘GLTVector3’ : undeclared identifier” , i know it is defined somewhere in GLTools.h , but i just can’t find where gltools.h is. Where can i download this file or it is included in OS? i am using winxp sp2 , and i’ve downloaded glut lib , but there is none GLTools.h in it.~~~ 
BIG THX.
all the samples file includes a head file called “glt.h”
search the glt libs bu googlesman~~~ i can’t find glt.h anywhere , i’ve downloaded the latest source code of glt, compile it, but , dude , what’s it for??lol, i’m totally a noobie in gl. Still where can i find GltVector4?THX

maybe it’s the part of the header file
