Hi there!
After some time of coding and restructuring I finally managed to clean
up the repaint-code using the property-tree as interface for the data
between fg and sg. Now everything is calculated where it's supposed to
be: Environmental data in fg's environment, positional data in the
reposition code and color in repaint. Nice and clean ;-)
I'm using the following property-tree nodes for interaction between the
sun-code and the environment:
/environment/relative-humidity // data for repaint
/environment/atmosphere/density-tropo-avg // data for repaint
/environment/atmosphere/altitude-half-to-sun // data for calculating
avg density
/environment/atmosphere/altitude-troposphere-top // data for
calculating avg density
Is the location of the nodes ok, or should I move them somewhere else?
I'm really happy about the solution with the property tree.
Since everything is working fine, I can address the other points in the
coming days.
