Hi all, happy guyz,
I'm working about an architectural project, a museum, a great project that
is born when I look at my first radiosity image (look the file, please).
I use PoV - Ray from Dos version, but only for joke...
now I have nice ideas and PoV - Ray 3.1 seems to be the right choice, 'cause
it's free, it's powerful ( not having a visual reference when I work, I must
concentrate a lot about the idea and not about the program, I think ) and it
has a lot of communities !!!

And so, here it is the question:
for a great museum, a great radiosity rendering, I need a great camera :),
especially a 16:9 camera and I have problem setting the dimension, aspect
ratio and so on about that camera.
I've seen yet the help file, but if you are still read this mail ( and so
you are not sleeping ), you will understand I have yet problems.
I will appreciate any help of any type: links to tutorials, to documents, to
addresses of girls or to ' how making money very fast' or to both things, or
a direct solution for this problem or simply a word of encouragement.
Thanks and bye,


P.S. Sorry for bad english and for nice question.

I suppose your problem is that your image gets stretched when you set the
16/9 ratio at the command line. ( +W1600 +H900 for example ).

Here is a short answer (but the best source of information you'll find is the
POV-Ray
Documentation, which is normally provided with the official distribution ) :

as you know it, by default, images are rendered for 4/3 ratio resolutions (640
x 480 for example).
So POV supposes the following lines are implicit in your source file :

camera {
    location ...
    look_at ...
    right < 4 / 3, 0, 0 >     /* Direction of the "right" of the camera */
    up    < 0, 1, 0 >           /* Direction of the "up"   */
}

That's why the problem arises when images have an aspect ratio different from 4
/ 3.
In your case, the only thing you have to do is to change the first commented
line to :

...
    right <16 / 9, 0, 0>
...

This way, the renderer will compensate the deformation introduced by your
"original"
aspect ratio of 16 / 9.

For more info, on cameras, nothing's better than POV's Docs and example source
files.

right.  and welcome to the newsgroups.  you will want to read the
announcements newsgroup (all of the messages).  in them you will find
the proper useage for these groups, rules, etc.  this is a friendly way
of telling you that the image that you attached is in the wrong
newsgroup.  the povray.binaries.images group is where all images should
be posted.  commonly, if a message requires a picture for explaination,
you should put something similar to the following in your message:

"...<your problem>...

see the image i posted in p.b.i to see what i mean.

..."

by the way, no need to appologize for your english.  do your best to get
your point across, and we'll do our best to understand:)

Hi,
Skippy Fastol, for the moment, thanks and sorry for these thanks that are so
late !
Ryan Constantine thank you for your suggest and I hope you consider this:
the initial problem was to find the povray communities, I didn't believe
that was a server a part and I didn't believe that are all these newsgroups
:))
So I'm sorry for this situation, but like my gradfather was used to tell:
'One victory can only teach you how to enjoy, much defeats teach you how to
live'.
Sorry again, Ryan.
See you later,
