Multi Laser planetarium in python3 for LJ.
v0.01
Sam Neurohack
Accuracy could be tested against apparent data and starchart at https://www.calsky.com/cs.cgi?cha=7&sec=3&sub=2
Remember to set the same observer position and time.
See Readme for more information
Todo:
- use debug mode and check altaz calculated values against online sites.
- Validate aa2radec() with online calculator. Rewrite it to remove need for Astropy.
- Findout how to use OSC in python 3.
-
- Code WebUI page.
- UpdateStars() in each laser sky. Get magnitude. See UpdateSolar for example.
- All Draw operations should also check visibility in the given laser altitude range.
- Rewrite CityPosition() with proper search in a python dictionnary.
- Better python code. Better varuable to understand easily Update() methods.
LICENCE : CC
Remember : LJ will automatically warp geometry according to alignement data. See webUI.
