Fat triangulation (Equilateral triangulation) help

[gigilibala]

Hi everybody

Do anyone knows a way to make a simple mesh like a simple plane but with fat triangulation? I mean most of the triangles will be Equilateral triangles.

Do anybody knows any tool for making this kind of meshes or how can I build them, for example, in 3Ds Max?

I want such kind of meshes in order to import them to Irrlicht.

Thanks for help.
