Hello, all.

Well, this was fun to do.  It initially started out as an experiment in
camera shake -something which becomes apparent towards the end of the anim -
but other things came into play (as they always tend to do when POV-ing).

The slightly jerky pull-back at the beginning was because I got the timing
between the camera angle and camera location slightly wrong - and I can't be
bothered fixing it tonight.

The lamp falling over at the end isn't quite perfect, but it's not bad for
one evening's work.

Thanks go to Chris Colefax for his Auto Clock Modifier - it would have been
a lot more work to do this one without his spiffy software.

And apologies if the mpeg encoding is a bit naff - my first attempt at
customising a .ctl file.

Bye,
Alan.

LOL ! Very nice (even nicer if there was some debris).

That was fun, good camera shaking I thought.  The lamps floated as if
underwater.  Was the red one supposed to blink?

Ta.  Done by affecting the camera's location and look_at vectors by a random
amount 'sampled' from another variable - all done using Mr Colefax's Auto
Clock Modifier.  The code looked something like this (apologies for the
line-splitting), and keep in mind that the stone ball hits the floor (and
the robot) at clock=0.6:

#local camera_shake=(
  From      (0,0)
  To        (0.6,0)
  To        (0.61,2.5)
  To_Using  (0.7,0.1,"D")
  To_Using  (1,0,"S")
);

#local real_lookat=(
  From    (0.0,<-1,10,0>)
  To_Using(0.65,<0,10,-60>,"D")
  To_Using(0.7,<0,10,-50>,"A")
  To_Using(1.0,<0,10,-20>,"S")
);
#local
cam_lookat=<real_lookat.x+(rand(seeder)*camera_shake/2)-(camera_shake/4),rea
l_lookat.y+(rand(seeder)*(camera_shake*4)-(camera_shake*2)),real_lookat.z+(r
and(seeder)*(camera_shake*4))-(camera_shake*2)>;

#local real_campos=(
  From    (0.0,<0,6,-50>)
  To      (0.1,<0,6,-50>)
  To_Using(0.35,<0,6,-70>,"S")
  To      (0.6,<0,6,-70>)
  To_Using(0.65,<0,15,-70>,"W")
  To      (0.7,<2,6,-70>)
  To_Using(1.0,<2,6,-60>,"S")
);
#local
cam_campos=<real_campos.x+(rand(seeder)*camera_shake)-(camera_shake/2),real_
campos.y+(rand(seeder)*camera_shake*3)-(camera_shake*1.5),real_campos.z+(ran
d(seeder)*camera_shake)-(camera_shake/2)>;

//  Camera
camera {
  location cam_campos
  right x*image_width up y*image_height
  angle From (0,30) To_Using (0.35,70,"S") To (1,70)
  sky <(rand(seeder)*camera_shake/4)-(camera_shake/8),1,0>
  look_at cam_lookat
  perspective
}

The seeder variable used in the rand() statements above was set using Yvo
Smellenbergh's tick_count function which, though useful for the purposes of
geting a fresh bunch of random numbers for every frame, has the side effect
of making every render of the total animation different - I think!  Correct
me if I'm wrong...!

> The lamps floated as if underwater.

Hmmm, I know.  I'll have a fiddle.  And then edit the scene.  The trouble is
getting the timing right with these things - render and re-render.  It would
be easier if I could get used to doing things visually in something like
Moray - but I prefer the handwritten approach.

> Was the red one supposed to blink?

The red one *is* oscillating a bit, but I think it's too fast for the camera
to catch properly.

This whole anim was just an evening's hack, but it's triggered some ideas
and also given me the incentive to try something bigger.  IRTC - here I
come?!?!

See ya,
Alan.

Ta.

I was going to have the ground crack up a bit with some dust and stuff
flying about and also have the robot realising his mistake and attempting to
run off just before being splatted - but then I realised that The Rock (no
relation) was coming on the telly so I turned the computer off.

This has actually triggered off a whole story in my head, so I think I'll
have a go at expanding it.  Maybe.  If I've got the time.  And that.

See ya,
Alan.

Hey, we were both watching the Rock at the same time - that's really, well,
really not that unusual I suppose. (love that movie).
