    ------------------   
    DEFO1 = CINEMA GEO1 GEO2 GEO3 VEC1;


    Description :
    _____________

    This procedure generates an animation of a object GEO1 according
    to a succession of view points GEO2 and view directions GEO3 for a
    fixed direction of the observer head VEC1.

    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)

    VEC1  : direction of the axis of the observer's head (POINT 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 VEC1;
       OEIL1 = (GEO2 'ELEM' 1) 'POINT' 1;
       OPC11 = (GEO3 'ELEM' 1) 'POINT' 1;
       OPC12 = VEC1;
       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;
