Re: Project "Celestia Origin", release dated April 30, 2020

You need either rebuild Celestia against liblua 5.1 or edit scripts to replace table.getn with #. Simple installation of lua 5.1 binary package is not enough. I'm using Fedora 31 (XFCE spin), on an x86_64; I'm a decent enough user to be able to follow directions to compile this or that, but 'rebuil...

Re: Project "Celestia Origin", release dated April 30, 2020

I guess you can try downgrading to 5.0. And, as it turns out, I can't actually perform that downgrade. Lua 5.0 requires "libreadline.so.4()(64bit)" which is provided by readline 4.3, while I have readline 8.0 installed; and since the protected package dnf relies on the newer readline, tha...

Re: Project "Celestia Origin", release dated April 30, 2020

You need Lua 5.1 Alright; I just downgraded to Lua 5.1.4-9, and trying to run Celestia provides the exact same error message. Should I try going further down to 5.0? I don't suppose it's possible to turn off Celestia Origin's extra lua-stuff, and just take advantage of its objects, models, and so f...

Re: Anybody besides me tired of constant captchas getting here?

I've minimized the annoyances of this site's captcha-pages with a Firefox extension called " Privacy Pass ". With it installed, every so often I visit https://captcha.website/ and fill out some captchas, which adds 30 'tickets' to Privacy Pass each time; and one of them gets used up every ...

Re: Project "Celestia Origin", release dated April 30, 2020

I just tried installing Celestia Origin v11 core on my linux machine, on top of Celestia 1.6.1. The installation itself appears to have completed without a hitch. However, now when I try to run Celestia, I get this error message: Error: lua-applications/lua_universal_tools_v5/lua_universal_tools_v5....

Re: Writing a novel, seeking help with Celestia

Say, does anyone have an SSC for the Martian trojans, such as 1999 UJ7?

It looks like the Sol-Mars L4 point might be close enough to my spacecraft's course to be interesting, and I'd like to double-check that.

Re: Writing a novel, seeking help with Celestia

I was a little nervous when I started reading the instructions in the readme of SevenSpheres' .7z, but Janus's .ssc slipped into my extra folders without any effort at all, and is working just fine. :) I seem to have missed a step in SevenSpheres' Barycenter suggestion; I'll be spending a bit of tim...

Re: Writing a novel, seeking help with Celestia

There is a Lagrange points addon; the download links seem to be missing but it's included in Celestia Origin (I can put it in a zip file and send it if you want). I'd appreciate that; 8.3 gigabytes seems a little much to download to get such a small addon. If you have a trajectory file, maybe I can...

Writing a novel, seeking help with Celestia

I started a mid-year NaNoWriMo a few weeks ago, and have found Celestia to be a great help in pinning down the occasional detail. Is there any chance someone here could write a quick location-object or two, within a day or so, to help me with more visualizing? I'm not worried about what they look li...

Deliberately adding noise?

I've been playing around with Phobos models, reading some old posts here, and have had a thought. From what I've been able to tell, the overall philosophy for Celestia seems to be to make it as accurate a solar-system viewer as possible - to be able to take the most accurate data available about a s...

Re: Preview Phobos

I think I've got a reasonably decent size-scale base set up, for my artist friend to zoom in and out and swing the camera around and so on. In case anyone's curious, here's the ssc info, and a quickie screenshot. SurfaceObject "Dome" "Sol/Mars/Phobos" { Mesh "domefix.cmod&qu...

Re: Preview Phobos

Specifying an object's orientation and long/lat on a spherical body are "easy" if you use one of v1.6.0's new directives. Getting the altitude right is going to take trial-end-error, though, since Phobos is an irregular 3D model, not a sphere. Here's the simplest SSC entry for placing an ...

(Nearly completely unrelated to the above; if I wanted to be silly, this would be the point where I linked to http://www.doomworld.com/pageofdoom/graphics/Wimap0.gif and suggested someone more skilled than I am at tweaking Celestia textures might enjoy figuring out the scale, and where on Phobos th...

Re: Preview Phobos

I do appreciate all the work that has been done on Phobos models and textures, and thank those who have done that work. John's model-and-texture add-on should do quite well enough as a reference for my artist friend, especially if I also show her the color-references Fridger posted. (Nearly complete...

Would applying your perl script to my existing, bumpier cmod remove the polar-pinch without smoothing the rest of the moon? No the script works from the *.tab data m1phobos.tab > m1phobos.cmod -- NOT -- old.cmod > new.cmod Thank you for the clarification. i have not looked for t00fri's map but as i...

Re: Preview Phobos

Hello, I haven't been able to find your updated Phobos model and texture on any Celestia site I know of; could you please tell me what it would take for me to produce similarly improved renderings of Phobos on my own computer? For various reasons I never upload work of mine to the Motherlode. I am ...
