Grasshopper

algorithmic modeling for Rhino

Creating a faceted facade

Hey guys,

 

I'm pretty new to Grasshopper, I've only used it a few times for very simple mundane tasks, but as of now I'm trying to create something outside of my realm of understanding.

 

Basically all I need to do is create a faceted facade(s).  There's two planes that are on the north and east face of the building, they're disconnected, but I imagine I can use the same command for both and just adjust a few sliders to get a different look and feel for each side.  I rigged together a script involving multiple points within my rhino model, but I'll have to add, delete, and then reset all of the points in order to adjust the facade when my project inevitably undergoes changes per my professor.

 

I feel like my best approach would be to create a somewhat random array of points on my surface and then adjust those points along the x/y axis and create triangles between all of them... sadly I do not know how to do this.

 

Any help is greatly appreciated!

it depends what you want to achieve. Take a look at voronoi diagrams, delauney triangulation, isosurfaces and maybe some kind of grid ? 

 

Also it would be probably nice to use attractors - maybe use sun vector as an attractor ? look for topics related with it - there are many here.

here you can find mine and Evert Amador solutions for attracting a custom shaped grid. 

You can also attract points to move perpendiculary to surface, after that use delauney triangulation.

This should give something like this http://designplaygrounds.com/deviants/tessel-kinetic-sound-installa...

Try this GH definition. It uses Mateusz suggestion of using the Delauney triangulation with randomized points.  Let me know if it works for you.

Hi Stan,

Thanks for sharing the script! Just wondering if it's possible to tweak it to apply to a closed surface such as a pipe?

Thanks in advance

Exactly what I was looking for.  I really appreciate the help!
