Day/Night Cycles in Kitely

[Deuce Halsey]

Can someone please tell me the timing of the default day/night cycles in Kitely? I have noticed it getting dark for a while occasionally, but it doesn't seem to happen nearly as often as it does in SL. The cycle in SL is 4 hours of daylight followed by 2 hours of night - so there are four complete day/night cycles in every real 24 hour day. What is the ratio here in Kitely?

I have tried looking in the estate settings for my world. But I didn't see any cycle listed anywhere, if indeed it is listed in there.

Thanks!

Hi Deuce,

We haven't changed it from the OpenSim default but I don't know what that default is. That said, considering many OpenSim developers' goal of mimicking SL behavior it is very likely to be the same setting as you have in SL.

Here's an extract from the example configuration file OpenSim.ini at:
http://www.ics.uci.edu/~lopes/teaching/ ... penSim.ini

Code: Select all

; Uncomment the following to control the progression of daytime
; in the Sim.  The defaults are what is shown below
;[Sun]
    ; number of wall clock hours for an opensim day.  24.0 would mean realtime
    ;day_length = 4
    ; Year length in days
    ;year_length = 60
    ; Day to Night Ratio
    ;day_night_offset = 0.45
    ; send a Sun update every update_interval # of frames.  A lower number will
    ; make for smoother sun transition at the cost of network
    ;update_interval = 100

So it looks as though a default OpenSim day is 4 hours. But that can be tweaked by Windlight OSSL commands (see e.g. http://opensimulator.org/wiki/OsSetSunParam) which are also supported in Kitely (http://www.kitely.com/virtual-world-new ... functions/).

I use a sun position sensitive script for various types of lighting, but wasn’t exactly sure how long a day is in Kitely. Conducting tests over several hours, now I know from empirical evidence and here are the results. Please note that I’m talking exclusively about the “Use Shared Environment” setting, which is what the script I use responds to. If you have your own settings, please ignore everything I say!

A Kitely day is 4 hours of real time. Sunset (when the sun.z reading of sun position is 0.00 or less) is at 21:08 Shared Environment time. Sunrise (when the sun.z reading of sun position is 0.01 or more) is at 02:48 Shared Environment time.

Because of the reasonable time for sunset, but very early sunrise, it means that in Shared Environment time, there are 18 hours of dawn to dusk daylight (3 hours of real world time) and only 6 hours of dusk to dawn night (1 hour of real world time).

If you prefer to use Shared Environment settings, I hope this helps!
