Can the sun position azimuth and elevation be set with Python?

[BrianMcAuslan]

Title says it all.   Thx

Edit

Note I'm not trying to calculate these values I want to assign them to the city engine environment settings. Idea is to set up a script as below.

assign sun position
set position by bookmark
snapshot
layer off.
layer on
snapshot
etc

set position bookmark
etc

Set new sun position
etc

Cheers

@nothing builtin but there are tons of libraries

Pysolar: staring directly at the sun since 2007 — Pysolar 0.7 documentation 

sunpos 1.1 : Python Package Index 

astral 0.7.4 : Python Package Index 

I could provide more, but I assume you have ruled out using externals

ok... I don't know what CE has for python methods and functions or properties, but certainly not within arcmap and arcpy.  I hate to send you back to troll through the help documentation but... The only mention of 'azimuth' was under 'light' for setting light source... but not direct mention of python

Hello Brian,

Sorry to inform you, that the sun can't be set via python.

The CityEngine team is aware of this missing feature.

I've added your request.
