Hello there,

Finally, I managed to finished my Season's greetings and send it of to a
copy shop. I stopped making X-mas cards years ago, because X-mas is too much
associated with the Church and commerce. Therefore, with the same benevolent
feelings towards my fellow humans, I make New Year's cards (although with
X-mas tree). This year it's the third one made with povray. I can send the
paper version (200 gram paper) just before New Year to all my relatives and
friends.

However, whoever reads this post can view my New Years card on my homepage
right now. Lucky you. The address is
http://home.planet.nl/~ejvermeulen/home.html and choose the link under
povray. I made the page just in fifteen minutes, so don't expect too much
from the lay-out.

I included some other files I made with pov-ray. At this moment, I should
thank all you guys and girls who have been a much appreciated help to me in
this newsgroup this past millennium. I have learned a lot from the various
questions and solutions posted here, and now and then managed to understand
and use some of the code supplied in the various povray newsgroups and at
websites. Thank you very much.

In the New Year's card I used a povray file I have been working on the past
half year, that should show the apartment where I hope to move to in April
or May. It's quite bare. However, should anyone be interested in seeing the
huge amount of inc files and the few items already placed (kitchen closets,
bath tub, 'the small room', couch, a simple television and computer), I will
be happy to send a 13 kilobyte zip file with the povray scene file and the
various include files.

Erik,
I too would rather not do a "Christmas" card, but I love the
traditions. I think almost all the "Christmas" traditions were
stolen from pagan Solstice celebrations but people don't
understand when you try to celebrate or wish them a happy solstice!

   here's my non-Christmas card, even though it says "Merry Christmas":

Harold,

I had already admired your X-mas card. I just took a look with a red/green
glasses, it's great.

How did you manage to obtain the 3D view?

Erick,
Stereoscopic imaging is the reason I got into POV-Ray. It is easy
to make a stereo (3D) pair. There are some complex formulae for
choosing how much separation to make between the left and right
rendering, but basically you can use the 1 to 30 rule, which states
that the left and right camera should be separated by 1 unit for
every 30 units between the camera and the nearest object (or main
object if the nearest object in small or unimportant). This rule
is based on the standard human eye separation (about 2.5 inches)
viewing something about six feet away. For the card image I used
something like this (I don't have the file here at the office):

// Left camera, render and save under a different name
camera

  location <-7.0,  5.0, -460>
  look_at  <-7.0,  0.0,  0.0>
}

// Right camera, render a second time
camera

  location < 7.0,  5.0, -460>
  look_at  < 7.0,  0.0,  0.0>
}

I this case I took into account that the fractal object was located at z*-40
so to get a 1:30 ratio the separation needed to be about 14 (420/30=14).
By moving the look_at with the camera you keep the cameras parallel, which
avoids keystone distortion.

However, you might be asking how did I make the red/blue anaglyph image from
the left and right image. Well, I used VRex's DepthCharge Developer Studio,
but it can be done easily with Photo Shop or Paint Shop Pro. It is easier to
do with Paint Shop Pro than with Photo Shop (IMHO). I can't give
you step by step instructions right now, but basically you open both images,
convert them to gray scale, separate the RGB color channels, then combine
the
Red channel from the left image with the Blue and Green from the right
image.
Then grab your red/blue (or maybe green) glasses and enjoy.

Thanks, I will try that (and I also prefer Paint Shop Pro abov Photoshop)

You should try using the red from one image and the blue+green from the other
instead of just grey.

Oh, I've tried them all. For images with a lot of red or blue the
gray scale method works best. When I convert stereo photos to
anaglyph I try them as color anaglyphs and gray scale and
choose the one that works best. I also use the Stereoscope Java
applet on my web sites so the viewer can decide for him/her self
which is best.

Have you tried mixing grayscale and color? I get some nice stuff that way.
