Re: Keyboard Short-Cuts For Orbit Lines

Will those orbit commands be made official? I want to add a nebula label toggle command for Frank, so it'd need to be something other than N if N is used for spacecraft orbits.

OpenClusters

The opencluster.cpp file doesn't do anything much yet. Is anybody working on it now? Frank asked me to add commands to toggle them and their labels, which is easy. But I know of no addons with OpenCluster objects to see the toggling work.

Re: Missing spacecrafts

Check to see if the capitalization of the models' filenames are the same as the capitialization used in the ssc files. The case in filenames matters in Linux.

Re: question concerning educational extras

You can use the --config command line option if your Celestia is new enough to specify another config file like this: celestia --config alt.cfg On Windows you could make .bat files specifying different config files with different directories specified in the extra directories section of the config f...

Re: Mimas's oblateness

I found something about Mimas's shape here. http://www.shatters.net/forum/viewtopic.php?t=6572&highlight=oblateness+mimas

Won't Mimas's long axis be pointed at Saturn? The oblateness parameter makes it oblate all the way around.

Mimas's oblateness

This picture shows Mimas's oblateness. http://saturn.jpl.nasa.gov/multimedia/images/raw/raw-images-details.cfm?feiImageID=40563 Wikipedia has the same picture and said that the long axis is 10% longer than the short one, which I also got with measurements of the picture. The mean radius is 298.6 km,...

Re: What is the "Mass" parameter in the SSC file used

The extrasolar.ssc file distributed with Celestia has a Mass parameter associated with each exoplanet, and the number used there is Earth masses, so while the actual units specified is irrelevant to Celestia (at the moment), for purposes of processing the extrasolar.ssc file (as I did when creating...

Re: What is the "Mass" parameter in the SSC file used

The mass is given in Earth masses, not kilograms. The masses loaded in solarsys.cpp and used by getMass() and setMass() in body.cpp are just floating point numbers with no units assumed by the code. The place where units are assumed is with the overlay display code in celestiacore.cpp. That code do...

What's the version of your "celestiacvs.exe" ?

I can't see the Levels 11 and 12 added on the 1.4.0pre6.


It is the lastest from the cvs this week.

Re: What is the "Mass" parameter in the SSC file used

Celestia can read mass, but doesn't do anything with it. I made a version of Celestia that uses it to display the mass and to find the density. Now Celestia requires both the period and semimajor axis. Maybe I'll change it to compute one from the other if the mass is given. I think it is in kilograms.

Re: Any news of...

Don't be afraid of not getting new Celestia executables. One was made available in a new thread in the developer's forum about adding new keyboard shortcuts for toggling orbits by object type. It's based on the cvs code. Now that Fridger showed me how to make patches, I also plan on making a patch f...

Re: Keyboard Short-Cuts For Orbit Lines

Thanks for the patch. I didn't get around to making one because I didn't know how to make patch files. I can use diff, but the diff files don't look like patch files. :?

Re: CVS deepsky.dsc

Are there any catalogs with the nearby small galaxies including satellites of the Milky Way and the Andromeda? Could they be added to deepsky.dsc? If there are no big catalogs with those galaxies, I'll make an addon for them.

Re: Keyboard Short-Cuts For Orbit Lines

I know where in the sources the keyboard commands are handled, so I'll look into it. I'll need to find how to set and clear specific orbits or sets of orbits.
