Trying to render a thin line whose orientation and distance vary


I am trying to copy this website : INSPIRATION by TOPPAN | INTERZUM 2017

I got a sandbox here : CodeSandbox - CodeSandbox. I am not sure the link is actually working.

The white lines I am trying to reproduce seems to have the same width in both works but they are discontinuous in my case. Is it an aliasing problem or my lines are just not wide enough ? I think aliasing is on as it is activated by default with fiber.

Thanks for your help.
