Half tone question

Not sure if anyone has ever messed around with halftones. But I am trying to something with halftones. But I do not want to use the dots I wanna do it with triangles. Does anyone know how to do this??? I have enclosed a sample of what halftones are. I want the same pattern just with triangles instead.

Oh yeah I am reffering to photoshop 7

I’ve worked with halftones a few times, but never tried any other shapes besides dots. The only way I can think of is to create the triangle design and saving it as a pattern then using it as a fill. So after you use it as a fill, you can go in and delete the areas you don’t need.

yeah I was thinking kinda the same, but that will be very tedious. You think there is a plug in out there that does this, or have you heard of one?

Well if you’re lucky then there might be a plug-in, but I’ve never seen or heard of one. :-\
