of course, pix_video (either USB or FW will work)

you can generate your 1-px lines as 2d planes and mapped your live video 
as texture.

If you would like to make use the 1-px lines (or any kind of Gem 
graphics)  as alpha mask or some sort of maks,

I think there're ways to do that but the problem is I dunno how to do 
that, is there anyone have any experience?
