Dear Frank,
Thank you for your thorough test and recommendations. I fixed the errors, and created a manual that could help people start with less technical experince too. But I agree, some technical knowledge is required.
I also added an --ansi switch, now letter, ledger, tabloid and ANSI C papers are available too. Will check the possibility of the raster output.
I like your "hex globe", resembles a water lily. Looking forward to what you make out of it.
You wrote: "I suggest that you should change your ecliptic drawing system. The straight line segments don't look right...". But those are beautiful curves! Just projected, and when you glue them on the globe they become curves (and the curve looking latitudes paralels) as it can be seen on my first trial. (Please ignore the inaccurate pasting and gluing, and the paper stretches, I am not skilled enough to do this, globe making is a distinct profession. I like the atmosphere of this video. )
As a consequence your "star-cube" idea would require some other kind of projection I do believe, this Cassini (or transverse mercator) with +/- 45° longitude difference is very distorted. Anyway, I lowered the lower limit to four gores!
Adding date marks onto the ecliptic is put on the todo list along wit RA marks.
Milky way? It doesn't sound being a weekend hack project ... :-D Will see if I have time.
