Hi!

I am trying to create a tower which is solar responsive.

Now i have created a parametric tower with floors which rotate amongst a centre point. I can change the rotation with a slider.

What i am trying to accomplish is to let the floors individualy rotate, so that the biggest surface of the facade is following the sun. I don't know how i can do that?

Can i let the sun be an attractor point and then let the facade follow the point?

And how can i easily get the sun in the grasshopper file. i am now trying with Heliotrope plug-in.

I have attached my grasshopper and rhino files

Hope anyone can help me!
