REQ>Sun Position-Time of Day and Geographic Data

[joegiampaoli]

The thing that also kind of makes this whole thing tricky is the sunlight color and sky color that change depending of the time of day. I know I can calculate each render with this data, I just wanted to know how possible it would be to do this in a more "automated" way, which would be nice by just selecting a location from a list, or entering your lat-long info and the time and date, with or without daylight savings time. Specially if a client requires an architectural render with this precise data.

YES: I am mostly speaking about blender. I know there are plugins out there for blender, but just thought it would be nice to see it as part of the blender>indigo system.

It's possible, there's equations in the original sky paper to do it.

yippy!

man, indigo is starting to have a really feature set! soon to be time-of-day-dependant sky, fractal cloud thingies, 64 bit builds, kool

as soon as my parents give the ok, im gonna donate a shitload of money to you ono

[joegiampaoli]

Shit, I have not donated lately! Thanks for the reminder...

Maxwell actually made you do this information to set the sun position (last I used it - might be different now).

Personally, I *don't* see the value in it. Calculate it yourself, if needed.

yeah and it's a PITA! It doesn't seem to correlate with the sun and time position in my exact location as well!

I prefer to set the sun exactly where I want it for the render

there also *might* be problems with the old sky model (I guess), it should work, like, perfect, for the new one, as long as the earthball has it's wider equator radius and it's smaller pole-radius. (and it's wonky axis, and.....)
