Celestia Forums

Hello, 5 years later I found my stuff back (ouch!) These are scripts adapted from the MPC Perl script by Arlene Ducao. I made them a while ago, so do NOT launch them without reading the content and adjusting URLs, etc. Otherwise you are likely to get errors all over :wink: Awful code by the way, but...

Hi Dirl,

i haven't been cel-scripting for quite a while now, and the links for the scripts are down because the hosting company closed my account without notice last year.

I will look into my old computer files and post again if i find it

I finally managed to find time to dig into vectors and stuff. It took me a while, but i think i now have a relative velocity (Vinfinity) display script. I checked solar planets velocities and some asteroid-Earth close approaches and it seems accurate. If anyone thinks it is not right, please tell me...

Hello Guillaume, i found this document on DonG scripting pages. It is about marking objects, not labelling features of objects (cities, geological sites, etc). I found nothing about labelling of planetary features in Cel scripts. Will tell you if i find anything. This is what you want to do, right ?...

Hi eburacum, thanks for your post. If you have any suggestion on the script, feel free to tell. Regarding your question, you can try this (newer) version it is ready for star support (a few code uncommenting is necessary, but it's all documented in the code). The problem i ran into is that Celestia ...

understood, thanks!

thanks again,

so the script could look at these error bar values for each object, and decide how many digits to use, right ?

can you explain me how you get to this number of 7 from the object's webpage?

thanks Selden, What are the Epochs of the different parameter sets? good call, the time of perihelion for this comet was : MPC 2453553.5 JPL 2453554.249694 so one of the two computations must be earlier/less accurate (?) After a quick search, I'd suggest using the parameters available from the JPL S...

Fridger and Selden: hi, i hope i didn't interfere with your discussion. Reading back your previous posts, i am beginning to doubt the orbital data i use from the JPL small body database can be used "as is" in Celestia without transformation. I am very unfamiliar with quaternions, planes of reference...

I'll jump on this topic: i made a script that converts data from the JPL Small Body Database into ssc files. see http://asolignac.free.fr/celestia/files.htm for examples of comet and asteroid files and http://asolignac.free.fr/celestia/scripts.htm for the celx "converter" script Note that the files ...

Hello Guillaume,
you can try this:


http://asolignac.free.fr/celestia/the_marker_beta.celx.txt


It's a first version, but it works.
bugs/suggestions from anyone else are welcome

Tu es fran?§ais au fait ?

Amaury

Your lists were very helpful by the way...

Hello Maxim, here are a few additional flags for the C7 section of the CELX def?° file, namely: automag, grid, lightdelay, locations, partialtrajectories & smoothlines. Amaury /C7"Flags" Asteroid Comet Invisible Moon Planet Spacecraft Unknown automag asteroids atmospheres boundaries ch...

did you try the console or celestia:print/flash commands to debug step by step? i would check if the subroutine exit happens before or after the period is returned.

not sure if this is of any help, maybe you did it already

amaury

Still working on it... (wrong radius formula)

amaury

oops, didn't know about that one, it clearly is safer.

Hello blueberry, the Earth is declared in the data folder, in the solarsys.ssc file, under: "Earth" "Sol" if you comment (#) or remove all the lines declaring the properties of a planet, it will disappear from the solar system you can also use these lines to replace the model or texture used, etc. D...

i get it : there should be a wait() right after c:requestsystemaccess() on line 242... i didn't get the error myself because my celestia config file had systemaccess on auto (i got tired of pressing (y) all the time while testing :)) i can't upload anything from work, and no home connection for a we...

Escape => ERROR :/

Uh ?!?
do you get an error when you press escape ?

Please do not use the current script as its output for comets is inaccurate. However the asteroid part is ok. I will upload a better one when it is updated.
