Try to add gluLookAt function which will tell the position of your camera/eye.
(If this is not the required answer,please explain the problem )

Many transformations ( translation, rotation and scale ) are apply by user to the scene and, i want to retrieve the camera view in the modified scene !! How can i obtain the viewpoint because after i must send it to Acis modeler in order it calculates hidden or visible lines ? I had no problem with Parasolid because it uses the same method as opengl ( i just send it the modelview matrix ) whereas i don't how can i make with Acis.
