It turns out these are in fact contained in a single 3D model for the entire
aircraft, so it has nothing to do with 2D. Apparently the problem is in the
models. ...
FWIW I'd like to suggest that it is a good idea for 3D modelers to test their
work at 16 bit depth buffer settings since a lot of folks are still running
modern laptop, consumer grade and Intel embedded chips at 16 bit for
performance reasons. Even though it involves moving layers further appart,
adjusting 3D instrument models to support 16 bit generally does no harm to the
appearance of the model at the normal viewing distance.
I disagree on changing the models or instruments. Looking at the code
the problem is obvious.
We ask for a depth buffer precision that is impossible to achieve. From
FG/Model/acmodel.cxx :
FGAircraftModel::FGAircraftModel ()
: _aircraft(0),
_selector(new ssgSelector),
_scene(new ssgRoot),
_nearplane(0.01f),
_farplane(1000.0f)
{
}
Jim, if you can compile FG, can you try with a near plane of 0.03 and/or
a far plane of 250.0 ?
Harald.
