Grid on the piston Sign In

I found there are some cross marks on a Nissan VQ V6 engine piston.



As shown above, there are some grid on the piston shirt.
Are those marks are designed for a specific purpose or just exist due to their manufacturing process?

Thanks.

Pistons from various mfg have this . I understand they are to relieve surface tension which helps prevent the proliferation of cracks.
