For anime, it's about camera points or translate all camera. I try different
way, and with this code there is the unique right vue on image, but.... there is
no move throught the spline. The clock turn round, but the camera stay right on
origin. What do you think about ?

The lines who have two slashs, give me bad result.



#declare CamSpline = spline{Spl_X_wing}

#declare SplineTransform = Spline_Trans(CamSpline,clock,y,.1,.5);

#declare pCam = <0, 0,1>;
#declare pCam_Transformed = vtransform(pCam, SplineTransform);
#declare pCam_L = <0, 0,-1>;
#declare pCam_L_Transformed = vtransform(pCam_L, SplineTransform);
///////////////////////////////////////////////////////


camera {angle 50*image_width/image_height


       // location CamSpline(clock)
      //look_at CamSpline(clock+.2)
        location pCam_Transformed
        look_at pCam_L_Transformed
 right   x*image_width/image_height
 up    y
 direction z*1
       // translate CamSpline(clock)
      //  Spline_Trans(CamSpline,clock,y,.1,.5)

}

Interesting, no?

So, later i find, an another solution but, for the clock's spline, the number of
point make many trouble in the scene.
The clock without number'spoint, like that, i can't use spline for camera
movement.



#declare SplineTransform = Spline_Trans(CamSpline,clock,y,.1,.5);

#declare pCam = <0, 0,0>;
#declare pCam_Transformed = vtransform(pCam, SplineTransform);
#declare pCam_L = <0, 0,1>;
#declare pCam_L_Transformed = vtransform(pCam_L, SplineTransform);


 camera {angle 50*image_width/image_height


        location    pCam_Transformed
        look_at  pCam_L_Transformed
 right   x*image_width/image_height
 up y
 direction z*1


}

Who know how, or why clock make trouble with clock*nbr_of_spline_point.

Thanks
