Being new to Celestia and CELX it is not obvious for me how to get my small C++ application, which is receiving/decoding real time coordinate information and quaternions concerning current positioning + rotation of two satellites to update positions of my two spacecraftmodels sat1.3ds sat2.3ds in Celestia. Please give me some hint on how/where to start.

Unfortunately, Celestia does not yet reread its data files while it's running. After your program writes the updated SSC file, you have to stop and then restart Celestia.

Thanks for your fast comment. According to http://celestia.h-schmidt.net/celx-summary-1.1.html under 2.4.5 you can read:".....1.3.2 You can access the x-component directly by using position.x (this works for assignment too: position.x = 1)" , Sounds like a CELX/LUA-script should be able to set the position.x, position.y,position.z for a spacecraft if you can make the CELX-script i call a C++-routine, which is fetching coordinate data from the network. How then to make the CELX-script call a C++-routine....?

No, you can only set the components of the position itself, but this doesn't change the spacecraft.

Hi, ovr -

I don't have answers for you, but I'd like to know what you find out. I'm trying to do something very similar. Thanks.
