I plan on entering the current round for the competition.  When I'm done
with my work, I plan to put it on my web-page.  But I don't want someone
taking it and using it without some recognition.  This has happened to me
before - someone put a link from their site to mine and used two of my GIF
animations.  So, I'd like to put my signature or name into each from of my
animation.  Does anyone know of a DOS or Windows tool that will allow me to
easily place text or superimpose an image into the corner of all my images
for an animation?  Currently my animation is at 360 frames, and I certainly
don't want to do it by hand!!

The only tool that is capable doing such a signature print is gimp.

The bad news is that this is a linux tool.
The good one is that I read some weeks ago that there is a port to
windows. I have no clue how good this port is but gimp is worth a try
even if have to install linux for it ;-)) .

You can write script-fu's in it that would search for all you 300+ files
and writes your name at a specific place. There might even be already a
script for that. Have a look.

I hope this was of any help for you!


Greetings,

Marc

Unfortunate for me, its not for DOS/WINDOWS...... the search continues....

You're sort of in luck. With the help of some of the kind folks in
another povray newsgroup (actually, a LOT of mathemetics help) I have
some povray 3.1 code to place a line of copyright text on the bottom
right of your animation frame no matter where the camera is looking.

Simply put, you put your camera location in the vector cam_l and
look_at in cam_lat. The following will set your camera using those
variable AND, most importantly, compute the translate and rotate for a
text object that it will place just a widget in front of the camera
lense.



//example
#declare cam_l = <.6,5.4,16>;     
#declare cam_lat =  <15,1,24>;
            
#local CamZ = 2; //the amount of camera zoom you want

#local CamD = vnormalize(cam_lat,cam_l);
#local CamR = vnormalize(vcross(y,CamD));
#local CamU = vnormalize(vcross(CamD,CamR));

Oh. Before I forget. There are some special considerations you might
need to take into account since the text is an actual object. Things
like shadows, reflections, etc. This could or could not be used to
your advantage.

It could also be used to create a HUD (heads up display) similar to
the mecha animation canyon.mpg in the last compo. Or to position an
angry bee in front of the camera buzzing about while you follow it
from flower to behind etc. :)

Considering that the image frames (most, not all though?) already exist, you 
would need to redo the animation from the start.
Using Lewis' suggestion, however, can still work by rendering only image_maps 
of the whole animation (a very fast way to re-do an animation). I made a thing 
I call "inxframe", an include file to do just this in a few different ways.
Only problem with it is figuring it out and getting it to work right. I more 
or less got to a point with it and stopped, but if you look at the example I 
have at the top of my links page you can see what is possible:

Hope you can use it if you try it.

Well, there's really a port to Win 95/ WIN NT. I looked it up at 

http://www.vtt.fi/tte/staff/tml/gimp/win32/

To my regret it has to be called alpha (maybe beta).


Povingly,

Marc

  Location and look_at... ok, but what about angle, sky and right?
  The right vector is not usually changed during an animation, but the
sky vector is very usually changed and also the angle (see the most probably
winner animation "the pool shark" at irtc :) ).

Well... for that you'll have to refer to the conversation in.... um...
the general newsgroup I think it was. I understood the concepts, but the
mathematics escaped me, so some kind folks straighted out my code there.
I believe the their rewrite originally contained sky vector transforms
but I cut it out to keep things simplier for my understanding. :)

It's essentially the same thing as the lensflare maths though. If you
understand that.... I've since used it to compute vectors for weapons
fire in an animation, as well.
