d13 Posted December 1, 2017 Share Posted December 1, 2017 Hi Everyone! Ok - crazy idea time! First of all, I discovered this: http://stars.chromeexperiments.com/ Pretty cool! I discovered that it's based on this CSV database of star positions: https://github.com/astronexus/HYG-Database I'm building a model of the solar system, so I now I thinking "wouldn't it be nice if instead of a skydome to surround my planets, I actually plot real stars as particles!" I'm just musing through this right now, by my guess is that I would need to extract the x/y/z position values of each star (with the Sun as 0/0/0) and then create particles for each one. Does that sound right? If so, my first step is to Decode the CSV file: https://raw.githubusercontent.com/astronexus/HYG-Database/master/hygfull.csv Here's the first line (with the headings for each data item) and the first entry: StarID,Hip,HD,HR,Gliese,BayerFlamsteed,ProperName,RA,Dec,Distance,Mag,AbsMag,Spectrum,ColorIndex 1,2,224690,,,,,0.00025315,-19.49883745,45.662100456621,9.27,5.97222057420059,K3V,0.999 All I need is the x/y/z coordinates - do any of you out there know which of those values refer to them? Thanks!! Quote Link to comment Share on other sites More sharing options...
