Collecting outside points

quick question, and hopefully not a stupid one. I have a custom 3d cellular automata script i wrote in rhinoscript and i would like to take each cell and dispatch only the outermost faces to apply a…Continue

Girih shape tiling and packing
Hey guys I'm doing independent research studio at school and we are working with the girih shapes. Instead of perfect tiling we are arranging the shapes so they leave these planned gaps (almost like…Continue

cull outside faces

so after seeing the new 3d voronoi component (very awesome btw! thank you!) i wanted to recreate a manual 3d voronoi project i did. for the last part im looking for the easiest way to cull out all…Continue

at first i thought this was happening because i had saved the components folder so the grasshopper plugins i had wouldnt be removed. after deleting that folder and completely re-installing…Continue

Aaron Coffman replied to mohammad's discussion How to Draw special grid?"glad i found this post! i tried to ive it a shot with your instructions michael but i seem to keep getting errors when replacing the points back into the list. could you point out what i did wrong? im sure its something stupid i…"
Mateusz Zwierzycki replied to Aaron Coffman's discussion Collecting outside points"This one should do the job...
Approach in two steps :
cull bottom and top faces first
use convex hull to determine which faces are outermost
You can achieve same effect with top and bottom faces by using 3d convex hull*,…"
Aaron Coffman replied to Aaron Coffman's discussion Collecting outside points"hey mateusz thanks for the reply. the definition is close but perhaps a larger group of CA cells would help better. here is just another image to show the cellular automata grows at 10 long x 10 wide x 25 high. the highlighted…"
Mateusz Zwierzycki replied to Aaron Coffman's discussion Collecting outside points"Belive or not, these are only outermost faces :
If you want to delete faces which are top or bottom one, cull them by face normal at (0.5;0.5) parameter (eval surface component) - if normal vector's z value <> 0 then false, else…"

quick question, and hopefully not a stupid one. I have a custom 3d cellular automata script i wrote in rhinoscript and i would like to take each cell and dispatch only the outermost faces to apply a pattern to them. i attached a quick image of the outside faces. thanks everyone.See More
Aaron Coffman posted a discussionGirih shape tiling and packing
Hey guys I'm doing independent research studio at school and we are working with the girih shapes. Instead of perfect tiling we are arranging the shapes so they leave these planned gaps (almost like the rhombus piece but tighter). Is there a way I could use galapagos to analyze the edge lengths and get the pieces to tile? Arranging these manually is getting to be a pain so I was looking for a more automated way to arrange these. Thanks.See More
