hi to all.

Despite being a quite newbie on POVRAY, I'm in a hurry to finish an
animation idea. I planned 2 steps of movement and in order to ease the
work I chose Chris Colefax's Spline Generator .

Assuming that clock is from 0 to 1, how can I achieve the animation
below to play only during "from 0.0 to 0.5" ? I only want to move the
camera during the remaining part.

sample object:
------------------------
object { objectx
                 //#declare spline_clock = clock //what should I write
here?
                 #include "mySpline1.spl"
                 translate spline_pos
                 no_shadow
                 }

thanks in advance and forgive me if the question is too easy!.

perhaps:

> object { objectx


#switch (clock)
  #range (0,0.5)
    #declare spline_clock = clock;
   #break

  #else

    #declare spline_clock = 0.5;
#end

Simple:

#declare spline_clock=clock/2;

More involved: Use Chris Colefax's Automatic Clock Modification macro
(autoclck.mcr), but it only works fully with v3.1 at the moment.

You declare a variable to go from 0 to 0.5 based on the clock going from 0
to 1, like this:

#declare your_clock=(
    From (0, 0)
    To (1,0.5)
);

#declare spline_clock=your_clock;

Hope this useful,
Alan.
