believe you never free the content of the building bin list. That means the
pointers stored in the list are gone, but the building bins - the pointees -
are still

Hi,
I don't have any clue of the opengl and simgear based stuff, so I looked only
at the struct Building and how to optimize that.
In the attachment you can find 3 structs representing the data.
The original is yours.
'small' is a very small optimization that doesn't require you to map floats to
Hi All,
Emilian and Vivian have pointed out a problem with the random
buildings - they gobble memory. I'd like to get some advice on
whether there's any solution, and also to ask someone with more C++
knowledge than myself to take a look at the code and check I'm not
doing something stupid.

Using the default random building density, the tiles that are loaded
initially when sitting on the runway generates ~ 340k random
buildings.
We might be generating too many buildings then?
The greater Los Angeles area has between 13 and 16 million inhabitants
(dependent on what you count).

I don't think it's off-topic. The parameters I've used for generating random
buildings are somewhat a guess based on the densly populated regions of
the UK

Besides being totally off topic, you can't do that direct comparison.
First off, our default scenery lacks a lot of detail in the urban area
boundaries in
that area thus marking a far larger area as being urban - a far larger
area on which to generate buildings
That'd makes my point

Just by looking at how the terrain is textured in FG, I can say they are
defined as Urban.
And the mapserver seems to agree with that

Unfortunately not. Individual buildings aren't instantiations
of a small number of objects, as the random vegetation is.
Instead, a huge group of buildings are a single OSG object,
