Attention all POV-Ray artists:

StereoIMAGEnation

The Cascade Stereoscopic Club of Portland Oregon is a 3-D
(stereoscopic) photography club. Starting this year they are
sponsoring a contest in stereoscopic images, whether photographic
or rendered. Medals will be awarded but there is no cash prize,
although winning would feel good and look good on your resume.
There is a $5 entry fee. I would enter, but I can't because I'm one
of the judges ;-)  Deadline is June 9th, but you need to register early.

Submissions must be stereoscopic and formatted as a left-right-left
triplet. Visit their website for more specifics.

If you don't often render your scenes in stereo then you might want
to try it. The 3D effects are great and it is easy to do.

 *** Here is the basic way to create your left-right
 *** stereo pair as separate images:

First you create the perfect image (many of you have already!).

The next step is to apply the "One to thirty" rule. This heuristic is an
easy
way to calculate the separation between the left and right cameras. Find
the object closest to the camera, divide the distance between the nearest
object and the camera by 30. That is the amount you should shift your
camera between rendering the left and right images. You should shift the
look_at point by the same amount.

Render the left image with the camera at x - one half the "1 to 30"
distance,
then render the right with the camera positioned at x + one half the amount.
Shift the look_at the same amount. The resulting left and right images
should
make a perfect stereoscopic pair. Use an image editor to arrange the images
into one JPEG in a left-right-left triplet image. The total dimensions
should
not exceed 1200x500 pixels.

Please enter the contest, it represents a bridge between the 100 year old
traditions of stereo photography and the new world of ray tracing.

Let me get this straight.  We pay you $5 for you to deign to look at our
image, and if we win, we get nothing?  So, what exactly does this marvelous
entry fee pay for?

Nice racket if you can convince anyone to enter, which I doubt.

Well you don't pay me anything, It's not my contest, I'm just a
volunteer image judge. To give you some background, there is a
whole long standing tradition of photography competitions. They
have always had an entry fee. In a traditional photo competition
the entry fee would go toward paying for the return postage on
the photographs and paying for the rental of a hall to hold the
judging and showing of the slides/prints. I suppose the Cascade
Stereoscopic Club figured they needed some fee to cover costs,
even if it is only some printing and the cost of ribbons and medals,
but you'd have to ask them. I don't know. I had thoughts similar
to yours... why a fee if the materials are all electronic and hence
no postage?

I'm thinking of having the Oakland Camera Club do a similar
competition but without a fee. That would be because the club
gets it's web space and e-mail from me and I don't ask the club
to pay any part of the $220 a year that I spend to maintain the
web space and e-mail :-) then the club would just have to pick
up some printing and the cost of medals.
