Is it compulsory to enter the detail images?

Regards,
Oleguer

Rules http://www.povcomp.com/rules
4.i. "In addition, two detail views of disparate areas of the main image 
shall be submitted."

"Shall" pretty much signifies that they are compulsory.

Are you having some sort of trouble creating the detail images?  If so, 
maybe someone can help in that regard.

Hello,

Thank you very much. No for the moment because I'm going to try it for the
first time now. If I have problems I will ask here.

Best regards,

Now I have questions:
My main render is Width=1280 Height=960, I selected this space:
Start_Row=0.33 +E0.25 +SC0.55 +EC0.75
but I want to have this space of my main render at 1280x960 (as the main
render). If I render it with the same resolution .ini file it only uses this
part of the resolution ( Start_Row=0.33 +E0.25 +SC0.55 +EC0.75 ). How can I
do to use all the space?

Thanks in advance,
Oleguer

First, note that the area you choose isn't using a valid syntax (E0.25) and 
if we assume it to be +ER0.25 then the end row is smaller than the start row 
: it should be something like +SR0.25 +ER0.33 + SC0.55 +EC0.75. Also, 
assuming this is right, it  has an unusual format ratio of 3.33. This is 
perfectly valid according to the rules, but make sure that this is really 
what you want.

Second, look at the example given here http://www.povcomp.com/samples/

If by "using all the space" you mean rendering the detail view as a 
stand-alone picture without needing to crop it out, then you'll need the 
zoomin.inc include file (and perhaps to modify the camera definition) (link 
given in the page above).

However, it can be simpler to render the detailed parts using the partial 
render. If the relative width of the partial render is 20% (+SC0.55 +EC0.75) 
then render your image at 5 times the size +W6400 +H4800 using the partial 
render parameters and then load the resulting image in your favourite 
editing program to cut out the black borders (you don't need to be 
pixel-precise).

Hello Gilles,
Thank you to ask my question.
I understood my mistake and I corrected it. Now I used this code "+SR0.44
+ER0.66 +SC0.66 +EC0.79". I understood if I use this option I have to use
the zoom.inc.
But if I use the other option I have to multiply the image resolution by 5
and substract "EC0.79-SC0.55=24", in that way, the partial render is 24%.
Multiply 960*5=4800 and 1280*5=6400, so +W6400 and +H4800.
On the resolution box I have to put the main resolution (960x1280)?
Then I can cut the black borders using CorelDraw or Photoshop.
Did I understand all right?

Best regards,
Oleguer

(I assume it's +SC0.55 +EC0.79. Be sure of your parameters before rendering 
anything !!!!)

To your question: not exactly. Zoomin.inc is a macro that creates a camera 
definition according to the partial render parameters you give to it *** in 
your scene code ***. If you're using this macro, you must no pass the 
partial render parameters in the command line (or in the ini file). You must 
give them to the macro.

If you don't want to modify your scene code to use zoomin.inc, you can 
simply render your scene file using +w6400 +h4800 +SR0.44 +ER0.64 +SC0.55 
+EC0.75. It will give you a 6400 x 4800 image containing a "useful" (i.e. 
non-black) 1280 x 960 area, corresponding to 1/25 of the image, that you can 
extract with CorelDraw, Photoshop etc. Make a try with a 640 x 480 image 
first to make sure you got the technique right (you should get a 128 x 960 
useful area).

Yes, I'm sorry, the mistake was writting the numeber here.
I rendered the image like this +w6400 +h4800 +SR0.44 +ER0.64 +SC0.55
+EC0.75 and in BMP format is very big, it's 87'9 Mb. Is it normal?

6400 x 4800 pixels (30 Mpix image)  x  3 bytes (24 bit image)  =  92160000 bytes
which corresponds to the 87.9 MB you have (the BMP header adds a few more bytes).

	I'd suggest you save your images using a lossless compression format
such as PNG or TIFF.  Just use the POV-Ray +FN flag (for PNG) while rendering,
or convert the BMP to e.g. PNG using your favorite image editor.

Yes, I have converted  to .JPG and it's smoller, only 527 Kb.

Thanks,
Oleguer

I cut the black marge with Photoshop and when I put the file on the Internet
it says me that the area is more than 1/25 of the main image area.
What's the problem? Must I reduce the resolution of the image with Photoshop
to arrive at the same resolution of the main image?
That's the code "+w6400 +h4800 +SR0.44 +ER0.64 +SC0.55"

Thanks,
Oleguer

Note that I personally favour BMP for output. The main reason is that images 
of this size take ages to save in PNG in the image editing program I'm using 
(and in the other I tested), so working on large PNG files can be really 
painful. Saving and loading BMPs is extremely fast in comparison.

Also, while partial BMP files seem to be fool-proof, partial PNG files can 
be a problem (my editor don't open them for instance), so I don't think it's 
advisable to use PNG as an output format in this case (converting the BMP to 
PNG after the render is advisable). Of course, these PNG-related issues may 
not exist with the image editor Oleguer is using, so your mileage may 
vary...

Please carefully read the rules and check out and also carefully read the
notes how to compute the detail image area on the sample page at
<http://www.povcomp.com/samples/>.  These two pages explain in great detail
how the detail image area is computed and what the requirements are.

The message you get tells you that the area you entered as the area of the
detail image within the main image exceeds 1/25 of the total area of the
main image. The area of the detail image is what you entered on the upload
page of the detail image, in pixel coordinates within the main image. This
has nothing to do with the size in pixels of the detail image.

Visit POV-Ray on the web: http://mac.povray.org

But, if I put this code "+w6400 +h4800 +SR0.44 +ER0.64 +SC0.55"
For the detail image 1 it tells me that "Size: 2877x957, Main Area: 0/0 to
0/0   461 KB "
What is wrong? Is my code wrong? I must select an smoller space?
Yes Gilles, I get a BMP and then I cut it with Potoshop, no problem with the
size. The next time I will render it directly on PNG and it will be smoller
and easier to work with it.

Thank you very much,
Oleguer

If that's indeed your parameters then it's wrong since you didn't provide a 
+EC value. The detail view goes up to the right border so it's larger than 
the 1/25 required in this case. Just check the size of the image you 
submitted. It shouldn't be larger than 1280 x 960 in your case. If it is, 
cut some margins it until it fits. I don't know about Photoshop, but the 
editor I use has a feature that lets you cut out a precise area.

Ok, now I rendered with this code "+w6400 +h4800 +SR0.44 +ER0.64 +SC0.55
+EC0.75" and the image is very big, I cut all the black marge and I only
have my portion of the image and when I upload this portion of the image it
gives me the same advertisment.
I think the problem is I did the portion of the image very big, is it right?

Thanks,
Oleguer

Oh, yes, I have to reduce the portion of the image to 960x1800, like the
main image. Is it?

What is the size, in pixels, of the image you're trying to send?

Well, as you can see it's too big as you made a mistake while passing the 
partial render parameters. Remove parts of it until it fits in 1280 x 960 
(or 1280 x 957).

Gilles, the message Oleguer is quoting is from the povcomp submission
website.  It has nothing to do with the size of the image, Oleguer simply
did not enter any coordinates for the detail view area.

On the detail image upload page you are asked to enter the pixel coordinates
of your detail image location within the main image. You have to enter valid
location values there. As it stands, you did not enter anything there at
all!

So I don't have to reduce the size. Ok, I understood that part. But how can
I now the cordinates?

As I already told you, please read the description on the samples page at
<http://www.povcomp.com/samples/>.  It explains how to compute all
detail-image related numbers.  If you have problems understanding anything
particular on that page, please ask specific questions.  If you have
difficulty with the language, I would recommend to find a friend or relative
more fluent in English to assist you understanding the instructions and
explain them to you locally.  It is essential that you read and seriously
attempt to understand those instructions for anybody here to help you with
specific problems.

Yes, Ok I had read this web page. Now I used this code "+SR0.44 +ER0.61
+SC0.58 +EC0.75". The main picture is in 1280x960.
1280/25= 51'2 and 960/25= 38'4.
How can I now if my square is 51'2 width and 38'4 height? Because I supose
that if the square is biger than 51'1x38'4 I can't upload it.

"In the above example, detail #1 occupies the area 424,328 to 615,583 in the
960x1280 image. This equates to +SC0.441667, +EC0.640625, +SR0.25625 and
+ER0.455469. These values are simply arrived at by dividing the desired
column by the width (e.g. 424/960) or the row by the height (e.g. 328/1280).
These won't necessarily always equate to the exact pixel you want but it
will be close enough for the purposes of the submission."
424/960= 0.441667, so +SC0.441667.
328/1280= 0.25625, so +SR0.25625.
How do you know the other number that appear on the exemple? ( +EC0.640625
and +ER0.455469).

I suposse the coordinates are my code: 0.44, 0.61, 0.58, 0.75. Is it?

Thanks to all the people who are helpping me.

Best regards,
Oleguer

By performing the same computation as for the start row and column.

No, as the upload page clearly states, you have to provide the pixel
co-ordinates. The relative co-ordinates are obviously not pixel coordinates.
As you arrive at the relative co-ordinates by dividing the pixel
co-ordinates, you have to simply reverse this operation to compute the pixel
co-ordinates from the relative co-ordinates. For example 1280*0.44=563.
