    Re: where exactly did i click ?

    There is a method by which you can restore the screen space x,y coordinates

    gluUnProject maps the specified window coordinates into object coordinates
    using modelMatrix, projMatrix, and viewport. The result is stored in objx,
    objy, and objz. A return value of GL_TRUE indicates success, and GL_FALSE
    indicates failure.

    I tried this but i have not been able to get it to work so did all my transformation math myself and used screen space coordinates to retrive my x,y,z values.

    If anyone has been able to make gluUnproject work do post a code sample in here for reference.

    Thanks

    Dont argue with fools, they bring you down to their level and beat you with experience.
