Distributing Hexagons on curved Surface with Sun attractor

Dear all, could you please help me in this.., I have a little experience in working with Grasshopper, and my intent was to distribute hexagon panels on a curved surface, I started by lofting curves one and panelizing it later with Lunchbox, extracting the curved points and so forth, but indeed I wanted those hexagons to get affected by the sun point attractor in such a way to get smaller in some places and bigger in another but not exceeding a limit of getting intersected and actually the result is becoming a bit tedious and not exciting because the resulting panels in some point of the attractor will have the same size, I tried Image sampler but didnt work properly, so if there is any ideas can be helpful in enhancing this definition will be highly appreciated.
see attached files.

Hi.

In my opinion, your approach is much more like point attractor reponsive facade, not the sun responsive one.

You must consider that the sun is vast and far away from us, so the sunrays are always parallel to your facade.

In this case, your sun position according to your modeling setup is not very useful and only matter is hypothetical azimuth and altitude angle.

I've applied azimuth angles to cell opening intensity, whereas altitude to cell extrusion intensity.

Check attached. You can choose sun and point responsive mode respectively.

Hi Kim, thanks a lot for your reply, its perfect now I can choose between sun and point attractor as well and the facade openings will get affected (azimuth angles to the openings and altitude to extrusion amount) which is so simple and I dont know how it was absent on my mind.

thanks again

In addition to HK stuff get this attached as well (surface and curve are internalized).

Works with any number of attractors (if this make any sense) and either in push or pull mode.

With regard results:

Either you get the fast option ("interactive" so to speak):

Or the long way home (Rhino is pathetically slow when "solids" are involved - but Rhino is not a solid modeller anyway):

Thanks Peter it seems interesting, I have passed through but quickly and I need to understand it well because there is a lot of stages need to get focus on especially you have used C# scripts along with the definition, but anyway thanks so much and appreciate a lot your help.

Hi
I'm trying to check the issue, but I didn't find the attached files?
sorry but I'm really interested to this topic

hello,

I tried the similar file for flat surface instead of curved surface, but could not achieve the previous result. I don't know where is the error. Kindly help its urgent.
