The keyword for coordinates and data is:
NGC Catalogue.

As I said, I haven't looked for it yet, but if I find something, I'll let you
know. I also made a PHP script with which I can create Povray arrays from
databases, if helpful. But it takes time, sorry.

Please ignore the last answer, I thought the forum had deleted the first block.
-----------


Now I was curious myself and went on a short search.

Maybe this is the original one:
https://heasarc.gsfc.nasa.gov/W3Browse/all/ngc2000.html

The data can be found here (ngc2000.dat):
https://cdsarc.cds.unistra.fr/ftp/cats/VII/118/


A newer version maybe is this here, but I havent found a download-file:
http://www.klima-luft.de/steinicke/ngcic/rev2000/Explan.htm

This one could be a competitor of yours:
https://cosmos-book.github.io/catalogue/NGC/index.html

one should be able to do this using an ini file, ie have a script executing a
scene or frame specific query and write the result(s) to a POV-Ray-style CSV
file, which would be available in the scene/frame for reading.

I also have a similar workaround.
A PHP script that converts an SQL database into an array.
But it is a detour that is limited in flexibility.

Nevertheless the reference to the shell commands is interesting, I didn't know
them before. I'll take a look, maybe I can use my PHP script a little better
with it.

Thanks,
m

my guess is that you will be able to use that code with (comparatively) little
adaptation.

in which case, likely, the default setting in the global 'povray.conf' will
"trip you up".  you have to set "[Shellout Security]" to 'allowed'.

Thanks a lot, I have already taken and tested it, works fine with
AlaSQL, which I am using as a DB engine.

Thanks again, I will start an intensive search after completing
application. Filling DB with the content will be an endless
procedure :).

Sorry for the inconvenience, it was my fault - I forgot
to comment out debug info and all 13979 records of NGC were printed to
browser's page. Now it works fine - no more crashes, I promise :).

Glad to hear it, as I am now taking care about mobile platform(s) too.
In general, it will support desktops, mobiles and VR headsets.

But nothing to see there yet and it's only a template, which I am
turning into a real application very fast. Hope till Saturday it becomes
much more interesting :).

Thanks, very well, I will examine it later, as now I am too busy with
coding. I have also registered in this serious astronomic community:
https://www.cloudynights.com/
and hope for their support.

The most desired thing for me now is coordinates of constellation
bounds, as I would like to store them as vectors to control separately -
one by one, but not sure if such a thing exists anywhere.
