Equilateral Trianlular Paneling for Shell

Hi, i'm an italian student of Architecture.

I have to design the outer-shell of a conference room that is hovering above the ground.

Starting with the sections i got a loft that i tried to model using Paneling Tools and Lunch Box, but in both of cases I got ugly panels which are each different from the other. (see attached pics)

I know that's impossible to cover the surface with equal triangles, but I want to make them at least similar.

My aim is to make a structure like the blob of Eindhowen or the Salvador Dalì's museum in Florida. (pics)

I read a lot of topic on this question but I have not found a sufficient explanation or solution in those.

I found only a picture of the result I want, without tutorial (pics)

Can someone help me?

Can someone definitively resolve this issue by publishing an algorithm or advising a plug in??

thanks!!

MeshMachine from the Kangaroo physics Grasshopper plug-in will do dynamic curvature adaptive triangular remeshing from *any* type of input mesh, making and breaking connections to the same end result. You also need to install Weaverbird to access Plankton Mesh in order to convert the output to a normal mesh. Normally you would attach a timer to pace through MeshMachine iterations, but Kangaroo also has a Sequence component to do it all at once, and also MeshMachine can do everything internally in one step using its iterations input variable.

I've also assigned a ground outline curve to lock the edge in place with the original, which creates single ground web artifacts you can manually delete. My input is NURBS, since that gives a more uniform result than first converting to a mesh, for MeshMachine.

Thanks a lot Nik!!

It works greatly!!

I got a great result, (although still has to be finished). 

Thanks for the speed with which you responded!!

Beautiful. Play with the Adapt setting, to better match ground features with smaller triangles, and consider inputting a mesh instead of NURBS, after perhaps triangulating it manually, though the Adapt settings that create small triangles along tight features and edges, also gives a disturbingly less uniform overall dome. Such is a black box component.

Also play with setting Pull to 0 to quickly approach a minimal tension surface that may in fact fully collapse, but you just set the Iter to a smaller number, and it goes faster (less physics) and may result in quite elegant structures.

Dear Nik

Hello

I followed your discussion on this topic and need your help!

I just installed kangaroo and want to create a dynamic equilateral triangle mesh (Like figure 2) on poly-surfaces in Figure 1 at Kangaroo. I can't download the .gh script that you attached above. Could you please help me with like a sample script for a simple geometry like cylinder and the I will use it for my shapes? thanks a lot in advance!
