Fill faces

i´ve got a model consisting of triangles like this with a curve

I know I can fill it with triangles

but since i need a lot of them at different angles that way would take forever.

Is there a way or tool to make a face from that triangle?
Thanks in advance

Fredo’s Curviloft should sort you out.

heard of that but couldn´t find it in warehouse.
Do i need an account of that website?

Yes, but if you read the page properly you will see the link to create a free account.
Sketchucation predates the warehouse and many excellent developers only share there.
And considering how much work it will save you it would be worth donating something to the developer.
