Do you expect your computer to handle 100m just as well as .6m?




Tips for finding Earth-Like planets: Look for F, G, or K Class stars. M class habitables will almost always be tidelocked. Oceanias can, of course, also be habitable, they just have tiny amounts of land.

I think that my computer can load 100M galaxies. ComCypher said that we can see max 2M galaxies, so I think there aren't be problems. But always when I'm open SE only recomended catalog is opened.

Try to instal new version (9.7.2 or newest). I have SDSS addon in this version and I don't have any traveling problems (only I don't know how t instal experimental). You must look to your computer parameters because lot of galaxies (600.000-2.000.000) can crush computer.

Hi!

PanM: The 9.0.7.4 = 0.9.7.4 patch 6. smile I typed it wrong. With patch 5 is good works. But only E-type galaxies at the error occurs with patch 6.

Could someone revamp this mod into a .csv file? Because SpaceEngineer said it would load faster if you did that.

Is CSV an acceptable format now? I've been out of the loop for a while...I might look at doing another update now that SDSS data release 13 is available.

It is now the preferred format!

Code

Name,Type,RA,Dec,Dist,AbsMagn,Radius,Quat.w,Quat.x,Quat.y,Quat.z
NGC 1077-2/NGC 1077B/MCG 7-6-68/ZWG 539.95,SBb,2.76720007,40.093299,171388274,-19.07,12463.208,0.840432,0.534431,0.0164455,0.088246
NGC 1000/MCG 7-6-48/ZWG 539.67/NPM1G +41.78,E0,2.64690011,41.4603005,140145941,-20.13,14269.0703,0.761034,0.552704,-0.274793,-0.199585
...

(From the 'NGC-IC.csv' file that is in the 'Catalogs0980.pak' archive.)





Don't forget to look here.

Yes. And Vladimir said:

This addon should be updated. Better to converts catalogs to .csv - they loading faster and have smaller size.

Changelog: 2.0
  • Refreshed the galaxy collection using SDSS-IV DR13 data. Surprisingly there are 3 million fewer galaxies now than in the previous collection, but this is probably due to improved data cleansing.
  • Reprocessed the catalog files to use CSV format, which should result in faster loading times.
  • Galaxies have been relabeled according to the official SDSS designation format (SDSS JHHMMSS.ss+DDMMSS.s).

    Nice! I must update procedural galaxy generator using SDSS luminosity/type distribution. Do you have some links for me te read about this?

    Actually the type distribution that I'm using is rather simplistic and doesn't take into account variables such as distance. I believe I took my calculations from here:

    http://scienceandreason.blogspot.com/2010....es.html

    Now that you mention it, maybe I should have just left the classifications out of the CSV and let SE handle the calculation (for the non-Galaxy Zoo galaxies). I assume that Type isn't a required column?

    EDIT: Space Engine loads now, the sdss was downloaded as a .zip, so I converted it to .pak. I can see all the csv files load, but when in game I can't find any SDSS galaxies in the catalog.

    Thanks btw

    OP: Hi, this is a great add on, however the new version crashes space engine every time it loads for me. I have tried unzipping the folder, and leaving it unzipped. With it left compressed, there aren't any evidence of ssds galaxies in the program. Uncompressed, the program gets stuck loading the individual csv files and disappears. I'm not sure what I'm doing wrong, or maybe my pc just isn't fast enough before the program times out? lol
