No, what I did was increase direction

#declare CamFactor = frame_number/100;
//#declare CamFactor = 1000;
#declare CamAngle = frame_number;
#declare Cam0Location =  < 0 , (1+CamFactor) ,0>;

#declare Cam0Location = vrotate(Cam0Location, <0, 0, CamAngle>);
#declare Cam0Location = vrotate(Cam0Location, <0, CamAngle, 0>) + (<-3, 3, 
-3>*(1+CamFactor));



#declare Cam1Location =  <8.0 , 1.5 ,5>;

/*
  Declare the illusion camera pointing along the z-axis
*/
#declare UseIllusionCamera = 1;
#if (UseIllusionCamera)
  camera {  
        location Cam0Location
        look_at   <0.0 , 0.0 , 0.0>
        direction z * CamFactor
        right image_width / image_height * x
    }


Doing it this way gives me a perfect view on what the difference is
