If you are talknig about "filling space structures" there are a lot of approaches, everything depends on what you want.

 

Starting from the very regular ones to more caothic

 

very mathematical types

if you are looking for some "organic" or more "irregular" structures...

Hope this start might help, its a fast "aggregation" of interesting stuff for your matter

If you're interested, some of my sample models regarding tessellation etc are on my blog.

 

One of the sample models is emulating the Beijing Water cube  http://geometrygym.blogspot.com/2010/08/tessellation-in-grasshopper...

Thanks for your help, these where great to start my research on the subject!

Right now we have a more defined idea of where our project is heading to.. and is sort of complicated.

We are trying to create a parametric skyscraper with the spatial attributes of foam formations. I would like to recreate a foaming structure based on defined polyhedrons (so far I think we are going to use the two polyhedrons from the weaire-phlean structure) and contain them on a shell we created based on some site characteristics...

My big problem right now is trying to figure out if there´s a way to variate the polyhedrons size trough its growth to create a closer similarity to the real formation of foam (image bellow)... I dont care if there are empty spaces between the overal formation created by the sort of tessellation of the polhyedron resulting from the change on the size but I dont know if this would be ineficient structure-wise...

Do any of you have any idea if this can be achieved??

We´ve tryed joining this polyhedrons by their faces and making some of them smaller but still some of them overlap each other. Ive tryed tessellation from Jon´s StructDraw... and also Galapagos to see if there is an optimal solution but I´m not getting a good result... I dont know if I should try something like Rabbit to create this irregular formation of defined polhyedrons?

Im attaching a very ineficient test I was experimenting on..

I would really apreciate your opinion. Thank you!!!
