[Mesa3d-users] Where or where have my polygons gone?

[Evan M. C. <le...@ca...>]

I tried looking in the archives and the FAQ but didn't find an answer to
my question so forgive me if this has been answered already.

I'm making a 2D map.  Some of the polygons in this map are very very
small.  It appears that if a polygon is sufficiently small Mesa throws
it out.  I've got sections of my map which are always going to be
composed of _lots_ of little polygons and when they are not rendered I
end up with a big hole in the map.  If I change my orthographic
projection to look closer in at the hole I see that the geometry for the
polygons is valid cause they'll show up at close inspection.

In my application I don't mind that while rendering these small polygons
that the pixel used to represent them will be repeatedly updated until
I've scanned over far enough to start in on a new pixel.  I.E. last
polygon rendered gets it.  That's actually desirable for my domain.

Any suggestions?

Thanks in advance!
