Please can you offer some help on this problem, I have explored allmost all
resouces available to me.
here is a simple animation which will rotate a ball on first the X axis and
then the Y axis, no problem so far.
I want to create a multi stage animation with more than just 2 stages for
example:

Stage 1, rotate ball on the X axis
Stage 2, rotate ball on the Y axis
Stage 3, rotate ball on the Z axis
Stage 4, rotate ball on combinations of the ubove

once i have grasped the method of creating animations with more than two
sequence of events i will be able to create more complex animations.

Please! Please! help

Thanks in advance

Paul


Here is a simple scene that i created with the help of the povray
documentation.

#include "colors.inc"
camera
{ location  <0.0, 0.5, -4.0>
  direction 1.5*z
  right     4/3*x
  look_at   <0.0, 0.0,  0.0> }

light_source
{ 0*x // light's position (translated below)
  color red 1.0  green 1.0  blue 1.0  // light's color
  translate <0, 4, -10> }

sphere { 0.0, 1
texture {pigment {radial frequency 8}}

//First stage of the animation
//Rotate X Axis 360 deg.
#if ( clock<1 )
rotate < clock*360, 0 ,0 >

//Second stage of animation
//Rotate y Axis 360 deg.

#else
rotate < 0, 0, (clock-1)*360 >

#end
}

In the news group povray.announce-frequently-asked-questions is a complete
list of Pov related on line tutorials. Some of these are relaed to animation
and this topic is covered quite well. There is also a new tutorial not on the
list yet that might really interest you. It si lcated at the link below.

Thanks
I am reading with great intrest about the clockmod include and macro files,
it still seems rather complex at the moment but i am going to look at the
included scene files which should give me a better understanding of how to
use the files.

I usually use a #switch statement to make the different "stages" of the
animation - something like this (and I usually let each clock unit be
equivalent to one second):

#switch (clock)
  #range (0, 1)
  /* First part */
    #declare Clock = clock; 
    /* Everything in the scene uses Clock in stead of clock,
     * so that I can play around with the clock value. */
    #declare BallRot = <Clock*200, 0, 0>
    /* Rotate the ball 200 degrees during the first second */
  #break
  #range(1, 2)
    #declare Clock = clock - 1;
    /* Clock again runs from 0 through 1 */
    #declare BallRot = <1*200, Clock*150, 0>
    /* The ball was rotated x*200 before, now rotate it 150 degrees
     * around the y axis. */
  #break
  /* ...part 3 inserted here... */
  #range (3, 4.1) 
  /* You should make the end of the interval a bit larger, otherwise
   * the final frame may not be rendered correctly. */
  #break
#end

You could also have a look at the scene files for my entries in the IRTC
animation rounds - Four Seasons in the Oct-Jan '98 round, and Revenge od
the Dragon Lord in the Apr-Jul '98 round.

Good luck!

I must be doing something right i was actualy looking at the switch range
and break operators for making multi stage animations but i could not get
them working, with your example i can build on that and develope the
techniqe further, once again thanks for your help

This reply is probably too late, but check out

http://www.spiritone.com/~english/animaker/animaker.html

which is on my website and I use a variation of the #switch statement. The
thing works and hoepfully it explains it well enough. I haven't touched the
project for a while but if you are stuck, maybe it will help
