[Flightgear-devel] Random Buildings improvements - phase 1

[Stuart B. <stu...@gm...>]

Hi All,

I've made a couple of updates to the random buildings to address some
of the feedback received so far.

1) As suggested by Thorsten R. I've changed the placement algorithm
from random to a grid-like arrangement.  This should allow faster
scenery generation, as it allows me to reduce the building coverage
required in materials.xml to provide the same actual building density
in the sim.

2) As the algorithm is more effective,
/sim/rendering/building-density is now more effective.  I've therefore
reduced the maximum value in the rendering dialog to allow those
wanting to use a value < 1 more leeway in setting it via the rendering
dialog.

3) I've reduce the number of Drawables generated by reducing the quad
tree depth from 3 to 2, and reducing the number of LoD leaf nodes from
10 to 4. James Turner - I'd be very interested if this change improves
your framerates.

Next on my TODO list:  Integration with the Effects system. Watch this space!
