Re: New 64 bit 1.7 version suggestions and bugs

FMOD is not, to my knowledge, in open source. Why should this version of Celestia has FMOD functions embedded in the code? :(

Re: Interactive Addon: Invaders of Mars!

VERY impressive, incredible, Selden!!! The add-on is intensively coded in Lua (5.1). But I am wondering when Lua 5.1 has faded out and replaced by Lua 5.2, your add-on Lua code could be no longer compatible, unless Celestia forever uses Lua 5.1. This is also a worrying issue that has to add onto the...

Re: Upgrading Celestia with Lua 5.2

Having been struggling for the past few weekends to investigate and make Lua 5.2 (or 5.3) works in Celestia, the following are what I have so far found out: 1. The "upgrade celestia-1.6.1-alt-lua5.2.patch" (or under any other naming) could take Celestia through compilation, but beyond it c...

Re: Upgrading Celestia with Lua 5.2

It seems that Celestia will be ankered with Lua 5.1 forever or there are something buggy with Lua 5.2. Anyhow Celestia and Lua 5.2 do not work together :( .

Re: Upgrading Celestia with Lua 5.2

Hi, John

My OS is Windows XP, Win32 with Compiler VS2008 (also tried with VS2005 and VS2010).

The svn code under the version number 1.7 is really the same as Celestia 1.6.1 and SVN 5229.

Upgrading Celestia with Lua 5.2

Hi, Anyone has been successful in making Celestia work with Lua 5.2 (currently Celestia 1.6.1 is based on Lua 5.1)? I came across this site http://dl.fedoraproject.org/pub/fedora/linux/development/rawhide/source/SRPMS/c/?C=M;O=A where the download contain a patch file: celestia-1.6.1-lua-5.2.patch. ...

How to draw a line between planets or moons

There are ways to draw lines between stars, is it possible for Celestia to draw a line between planets and/or moons?

Re: New Horizons Add-On

Thanks to Chuft-Captain, it is a very helpful link.
It is encouraging to see some senior Celestians (or respectful old hands) are still around in the forum---a light of hopeful reviving in the dark for the community :) .

Re: New Horizons Add-On

There's no VSOP87 orbit for Pluto, so the errors in its position are much greater than for the other eight planets of the solar system. As an alternative to using an XYZ file for Pluto, you can use the JPL DE406 ephemerides with Celestia. ... ... ... This particular chunk of the full DE406 ephemeri...

Re: What is the unit of measurement in cmod models

CC

Umm, you're right and Celestia agrees with what you said. But my engineering inertia :wink: makes me think distance be gauged in light-year, astromomy-unit, kilometer, or metter--especially when I display a cmod model's size in a celx script, it is helpful to show the measurement unit.

What is the unit of measurement in cmod models

Hi

What is the unit of measurement of a coordinate value (e.g the values of the x y z of a vertex) in cmod models? Is it kilometer or just meter? or else?
