It depends what kind of geometry do you wish to triangulate.

"Planar Surface" with evenly spaced u&v domain, yes.

Otherwise "Curved Surface"with uneven u&v domain will bring many difficulties.

Thanks for your answer Hyungsoo Kim Mohamed Naeim Nik Willmore

as you can see in the pictures, i did it with Weaverbird but the problem that the triangles are not the same, and to get low cost for the construction we should do that with the same module, i tryed many time but i didn t find how to make it, 

I uppload the gh if you can help me.

thanks :)

I don't think it's more expensive when if you try to fabricate your elliosoid with different size triangular panels in this parametric world. But, there's probably another reasons why you want to fabricate it with equilateral triangles.
There's been quite a bit of research on this topic including...

I think kangaroo can equalize edges length

Specifically Kangaroo 1 instead of Kangaroo 2, using the MeshMachine component you can search for examples of use of on the forum.
