TOD resource

  1. To kick things off, a nice link Comso found.


    It gives dusk/dawn as well as sunrise/sunset times, so the duration of these events is included, which helps set the sun intensity value after the sun is out of view.

    Sun intensity drives the skies appearance, so is important even after the sun has dipped out of view (sun diffuse = 0)

    Feel free to post curve sets up, or other handy links, values, trends, anything that helps people make their own quality TOD sets for different places!

  2. Apart from that calculator, I also use this one for a different info set:


    The advantage of the one Dave posted is that it shows the durations of the daytime phases, including dawn and dusk length, which can be very useful. This one here has the info in another format and displays astronomic, nautic and civil dawn/dusk for example.
