After some intensive months of solving lots of personal issues, I will try now to come back to production here in the blog.
Today I started to work again a bit into Grasshopper, with the initial intent of grasping a bit of the VB.net language. The first task I set up to do was to convert an old Python script to calculate sun position information on a defined location and time. It was initially presented to me by Tobias Schwinn, which in turn based it on an original version from Carlos Lara. The math behind the sun position calculations was taken from this website.
It still does not do much. I will further work on another definition to create a sun diagram in Grasshopper, and later one to work out incident angles on objects. Please, keep in mind these are personal exercises, without much defined goal, and not entirely well written. But it might be useful for some people, so here it is.
