Stretch Pattern on Surface

Hi folks,

i got a problem to understand how the guys did the stretching pattern like for Museo Soumaya.

I tried to connect the vertical curve to the breps edges and then somehow stretching the points on the curve. Or maybe doing a pattern from points and then stretching is better.

Or to remap from one surface to another?

Somebody an idea?

Greetings,
Hendrik
