3D starmap software

Long ago I pulled someones 3D (xyz) frontier map coordinates off the web and plotted them with gnuplot.  This allowed me to rotate the map and view it from different perspectives but lacked because each star is just a pixel in the plot.  I added the star routes to help keep perspective.  Unfortunately gnuplot is not user friendly for game play and such.  I'd like to be able to zoom in/out, rotate, and click on stars for windows of system data and a system map.  I am wondering is anyone has every come across a 3D star map program that they like?<br /><br />-iggy
