This is just a c# conversion and few updated notes for the old post : http:\/\/unitycoder.com\/blog\/2011\/08\/09\/latitude-longitude-on-3d-sphere\/<\/a><\/p>\n

Instructions<\/strong>
\n– Attach the script below to your sphere (Unity sphere UV mapping is not suitable so I downloaded this sphere model<\/a> and scaled transform to 5)
\n– Add earth texture map to the sphere (its included in the old version package<\/a>)
\n– Add a marker sphere, scale it to 0.3 or so
\n– Assign marker sphere to “marker” field on the script
\n– Set lat long values in the inspector (default value is for London, get more values from here www.findlatitudeandlongitude.com<\/a> )
\n– Note: Rotate your earth sphere by 180 degrees in Y axis (otherwise marker goes to wrong position)<\/del> *Probably not needed
\n– The hit play to test it.<\/p>\n

Resources:<\/strong>
\n– Map texture was taken from somewhere here : http:\/\/visibleearth.nasa.gov\/view_cat.php?categoryID=1484<\/a>
\n– Original math code is from: http:\/\/www.actionscript.org\/forums\/index.php#post722957<\/a> *link broken..<\/p>\n
