What are the exact rules for displaying polygons which have width less
than one pixel on output screen ?
During playing with my particle system I was trying to create a rain
effect. I'm using thin rectangles to simulate rain drops. Everything is
ok as long as they won't get too thin - they suddenly start to
disappear/reappear randomly (depending on fact if they cross pixel
boundary I suppose).
This is not critical for my work - I can use textured polygons, which
are a bit wider, or play with LineArray instead. But this is a bigger
problem - do polygons are supposed to disappear when they are smaller
than one pixel in some dimension ? Will antialiasing help here to get
subpixel shapes drawn ? Is this graphic card dependent ?
