    ------------------   
    DEFO1 = CINEMB GEO1 GEO2 GEO3 GEO4;


    Description :
    _____________

    This procedure generates an animation of a object GEO1 according
    to a succession of view points GEO2, view directions GEO3 and
    directions of the observer head GEO4.

    Contents :
    __________

    GEO1  : object to be explored (MAILLAGE type)

    GEO2  : sequence of POI1 defining the successive locations
            of the view point (MAILLAGE type)

    GEO3  : sequence of POI1 defining the successive view directions
            (MAILLAGE type)

    GEO4  : sequence of POI1 defining the successive directions of the
            axis of the observer's head (MAILLAGE type)

    Remark :
    ________

    It is advisable to use the option DIRE of the directive TRAC in
    order to animate DEFO1. If FLO1 denotes the distance between the
    view point and the view plan, the following input can be used:

       DEFO1 = CINEMA GEO1 GEO2 GEO3 GEO4;
       OEIL1 = (GEO2 'ELEM' 1) 'POINT' 1;
       OPC11 = (GEO3 'ELEM' 1) 'POINT' 1;
       OPC12 = (GEO4 'ELEM' 1) 'POINT' 1;;
       OPC11 = OPC11/('NORM' OPC11);
       OPC12 = OPC12 'MOINS' ((OPC11 'PSCA' OPC1)*OPC11);
       OPC12 = OPC12/('NORM' OPC12);
       OPC13 = OPC11 'PVEC' OPC12;
       PC11  = OEIL1 'PLUS' (FLO1*OPC11);
       PC12  = PC11 'PLUS' OPC12;
       PC13  = PC11 'PLUS' OPC13;
