Hi,

Well, I did it the hard way. ;-) Sorry, it's my first animation ever.

camera {
   #switch(time_step)
     #range (0, 32.4999999)
         #local winkel = time_step / 64 * PI;
         #local xpos = -1.0 + time_step * .03;

         #local xview = xpos + 0.1;
         #local yview =0.30 + sin(winkel + 0.1) * 0.472;
         location  <xpos,  0.06, ypos>
         look_at   <xview, 0.02, yview>

         #declare bahn1_y = ypos;
