    Use the gluUnProject procedure. This is the format:
    Code :
    int gluUnProject(
      GLdouble winx,                   
      GLdouble winy,                   
      GLdouble winz,                   
      const GLdouble modelMatrix[16],   
      const GLdouble projMatrix[16],   
      const GLint viewport[4],         
      GLdouble * objx,                 
      GLdouble * objy,                 
      GLdouble * objz
