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?

Best regards,
Oleguer

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
