Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

mass generation of birds. They actually flap wings and appear to go forward, though if you look closely, the swarm goes nowhere.

Thorsten came up with a toy for mass generation of birds. They actually flap wings and appear to go forward, though if you look closely, the swarm goes nowhere.[1]

the main guidance principle for this effect has been that it has to be cheap because the vast majority of users will see it for a few seconds flying past. It's entirely unsuitable for things like following a migratory swarm with an ultralight. You get to see something that looks like birds in the scene - that's basically it.[2]

Birds are largely unpredictable which makes true simulation impossible anyhow. You could follow a group migrating birds but they don't fly indefinitely so now you would have to account for breaks and proper landing areas. Which is infeasible.[3]


to see birds, you technically need to:

  • have a recent FG (2016.2) with a working random objects code (there was a bugfix just a few days ago, even a week-old binary will not work)
  • have random objects on
  • run ALS
  • fly in a region where they are defined

(Just south-west of Barcelona airport at the river delta is a good place - but it's of course the whole landclass). They're low - some 100-200 m above ground. They're difficult to spot against bright background, but in the morning hours usually appear bright against the dark ocean. And they're small - so you need to get close to resolve them as birds, from the distance they look like dancing sparks or so.[4]
