Hello everybody :)

I would like to know how I can make a animation, it means, I have a 3d 
object, and I want to go through this object, using a specific way (I 
want to define a way, with a spline for example, and I want that the 
camera follow this way.)

Thanks to your answers :)

Take a look in the example scenes that came with POV for
animations\splinefollow.pov

Ensure that FirstPerson is set to yes (I've rendered it both ways and
don't remember whether it was initially yes or no)

#declare FirstPerson = yes;

In particular, observe this part of the code:

// First-person-view camera
// Follows the same path as the first aircraft
#if (FirstPerson=yes)
   camera {
      location 0
      look_at z
      translate <0,0.4,0.4>
      Spline_Trans (MySpline, clock*11, y, 0.5, 0.5)
   }
#end

The "11" comes from the fact that the MySpline in this scene happens to
be specified from 0 to 11.

The translate <0,0.4,0.4> simply moves the camera so that it is outside
the first aircraft, which also moves round the same spline in this
example.
