[Opensim-users] Graphic question: View distance (more than 1 region?)

[Teravus Ovares]

The other option for a view distance beyond 1 neighbor region is a
'megaregion'.     It's more complicated to set up, however, and has
some known border crossing issues out of the megaregion that place
your avatar in strange places.   Using a megaregion, you get to see
all of the region segments that make up the megaregion at the same
time up to your viewer's set draw distance and far clipping plane.   I
think the viewer has a hard far clipping plane that is 2500 meters.
You can see this visually http://www.youtube.com/watch?v=gmkJ1EJxCJc
when looking at the video, bare in mind that it's 4 regions wide and
32 regions long or 1024mx8192m.
