Tessellation of a cylinder with equilateral triangles

Hi everybody,

i need to tessellate a cylinder with equilateral triangles like this ( https://i.ytimg.com/vi/aGvF7ynmfuQ/maxresdefault.jpg ).

I have got all the points that i need to join with edges but i can't do it in the right way.

Using panelling tool i reached this result. 

I need all the points to be connected.

I attached the GH definition to understand how i create the points.

Thank you in advance!

Hi.

Your cylinder length is exactly five times of polygon edge length, so you just can divide each line 10 times and do as follows.

I don't have your plug-in(?) component, so I can't dig through your full definition.
