For the sake of simplicity - help!

I finally got to wire my logo’s geometry to make it ‘cnc’ worthy…
I’ve tried this countless times and can’t figure out if there is anyway to wire such a simple thing better?

This is the basic shape - from the hex points you join the non-adjacent points to make a polygon that intersects itself.


Couldn’t find how to make all triangles join themselves or how to split adjacent polygons to assign that checkerboard black/white color.

If you really want to bother with this! I can’t figure out (since months) the simple checkerboard (find intersection points) create the polygons and split them easy way to do this. It should be easy to make grids (tryiangle/hex or square) and checkerboard it, but again here i go bananas trying.

The other issue i found kind of silly was:
you can create a perfect shape with multiple objects with different colors/geometry but replicating the group with colors can be a problem but i think that’s me not linking lists to colors versus “inherited” color but it would be nice to just give a shape a color and replicate that, wouldn’t it? Would make assemblies much easier. Im just a newbie what do I now know?

Thanks for any pointers!

Simple, hah! :rofl:

Rigging a sail would seem much simpler on a 3 mast boat right now :roll_eyes:

I don’t understand your question. If it is a question of coloring a “Map”, just use Map colouring Theory. I made a small script for that. You specify the number of color, and the algorithm try. The only tricky part could be the frontier check, but it seems to work here.

I have seen the 4 color theorem page before - but wanted to stay away from ‘code’ - each time i tried a new geometry grid i found issues finding adjacency (without calculating the patterns grids (like going polar) - i wont give up :wink:

Script 1
brep.Faces[i].AdjacentFaces(); → ok, AHA, oulala! That makes it easier :slight_smile:

I m still not sure how to regress or recurse in GH… Again, i want to stay away from code. I might have to change that POV. This is far simpler!

I need to learn C# now :slight_smile:

I was just starting with familiarizing myself with phyton. Irony is that im trying to get out of coding life… Only 40 years i started! But my main weapons - hypertalk and powershell are showing limits - and while i dont see how to bridge Livecode gui to GH yet, it’s in the to-do-list. GH could use a HyperCard like add-on IMOHO.

Script 2 - As Neo would say, now i know C#. Simple code! Im not used to oop c++ coding - i know C medium well. But i see the flow and what is happening - never wanted to dig in before into the oops of it all. My main tool is Hypercard - objects are GUI lists of objects directly - just wrap your enterprise quest results and logs and i do in seconds. GH like this i still struggle (after 1 year).

Thanks that was a learning experience. 2nd day of holiday off work and the usual scripting - it’s nice to change types of work pressures. Im trying to add color to my renewed interest in design. You’re an Icon Laurent! I studied graphic programming a lot decades ago, you’re an insipiration when i see what you do. Wish i had GH 40 years ago!

Over the years I’ve tried both one and two times to make something similar.
I always wanted to be able to do this: (11.8 KB)

Thank you Laurent!


Where we do the remote GUI for our GH parameters, we could use a nice Hypercard GUI editor (with fields (lists, tables that are ‘intelligent’), pictures/graphics/themes that are GUI event->condition-> give you the right choices (feed into GH?) → make an intelligent GUI/App) and make a nice application delivery compiler for GH geometries… My 2 cents…

I really miss Hypercard like GUI tools in the GH canvas…

It feels just like home in GH as it would be in Hypercard… But it’s different.

Create a geometry in GH and have a ‘pic’ preview in the canvas would be helpful? It would save time to go check your Rhino view… Wouldn’t be for all cases but like a text field, it would be handy to show an output…

It’s definitely simpler.

Before Laurent replied I tried to simplify it, but it very quickly gets very tangled.

I began my professional work 25 years ago using sort of Graphic programming, it was names AVS then AVS express

I can’t think using Grasshopper without programming, it is a natural extension/simplification. My only advice is: do your own library.

@lars.renklint I am happy if this little code is useful.

Nice solution but you need to weave (and enter manually) points…

Like i did with the connections… Doesn’t solve the intersection/adjacence issue.

Goes without saying once you go in the rabbit hole.
My gripe is learning all the libs you used for your code…

Gets me away from the creative/woodwork side.
