Having got the 3D scenery around SanFrancisco to show I thought I might load up
KSFO with some A/C and see what the affects might be.The results were
Using the untextured model that David used gave 18fps
Using a textured 737 I have gave 5fps
Using the A320 textured model of Fred's gave 10fps
And using the 747 with textures the sim stalled any time I was facing the A/C.
Some of the other things I observed were.
You need to have a separate .ac file for each different textured A/C in the scenery.
Which would lead to rather large scenery files.
The model David used sits at 90deg comparied to the other A/C I used.
Each A/C sat at a slightly different height for the same set altitude.
eg: some half buried and some sitting in the air.
The frame rate drop seemed to occur no matter how near or far you are from
the airport.This would seem to indicate that we need some form of LOD.I know
AC3D has the ability to produce as many LOD models as would be required.
With only 27 A/C and the untextured terminal at KSFO it seems we are not going
to get a lot of 3D scenery before most of the lower end computers grind to a halt.
Some things that would help(just my opinion)
Being able to access the A/C models from their A/C folder.
The ability to use different textures on the one model in the scenery.
The ability to move around the scenery using the arrow keys and to transmit current
position to a file which could later be used to produce the stg files.
I provide this information as a talking point as to how we can improve FG.
I look forward to your comments and ideas.
Cheers Innis
