Move SGReadFileCallback and all its help classes into a new
ModelRegistry class that also provides an interface to add custom
callbacks for specific file extensions. SGReaderWriterBTG uses that to
keep any further processing from being done on .btg files. Various
namespace-releated cleanup was done on this code too.
Use only one shared StateSet to control GL_NORMALIZE. This removes
thousands of state sets from the scene graph.
Fix a typo that was causing two copies of groundLights0 to be added to
each tile.
When loading terrain, use DrawElementsUShort where possible.
Don't chunk unconnected triangles in the terrain into seperate
Geometry sets; make the sets as big as possible.
- Added a SampleStatistic class (from the old deprecated libg++) library.
- Make time statistics and printing conditionable
- Added an interface function to switch time stamp collection and printing
on and off from the application (defaults to off).
used short's extensively to represent counts of objects (number of points,
number of texture coordinates, number of traingle strips, etc.) and we used
shorts to index into larger structures. But this capped many of our structure
sizes to a maximum of 32768.
By switching to unsigned shorts in the future, we can double the maximum
object/index counts without losing anything. This was a pretty major
oversight in our original specification.
I have bumped up the native object file version from 6 to 7 and added code
in the reader to maintain full backwards compatibilty with version 6
scenery files (i.e. the current 0.9.10 scenery release.)

This fix removes obnoxious visuals (texture jumping) when a cloud
layer is moved due to a metar update or, more significantly, when
switching from metar to a scenario. Also, I switched to using a TexMat
to displace the cloud texture in order to avoid writing the texture
array every frame.
Put the ocean tile state set in osg::Geometry, not the osg::Geode, so that
is readily available during intersection testing and can be used to find the
corresponding SGMaterial.

The cause seems to be the condition in SGMaterialAnimation.cxx l.277
ignoring any texture update by the UpdateCallback (only there
<texture-prop> is looked at) without an already existing stateSet.
That in turn will not be created with a <texture-prop> alone l. 379ff.
Unless I overlooked some compelling reason contradicting, I'd like to
suggest allowing for a stateSet to be created for those situations
too. I think that would match the behaviour of animation.cxx
(PRE_OSG_PLIB_20061029) and is imho the more expected and also
documented one.
An apron around the tile hides cracks with coastal tiles.
The VectorArrayAdapter, which lives in the simgear namespace, is a useful
utility class for treating vectors as 2D arrays.

The original code forced a dependency in SimGear back to something that is
defined globaly in FlightGear, not a great strategy for a library with some
"general purpose" intentions.

mf: this patch is meant to be removed as soon as OpenAL got fixed. (The
OpenAL developers acknowleged the bug and announced that it'll get
fixed.) For removal try
$ cd simgear/sound
$ cvs diff -rAFTER_OPENAL_DOPPLER_WORKAROUND -rBEFORE_OPENAL_DOPPLER_WORKAROUND|patch
shouldn't be affected -- marker beep, ATIS messages, etc.)
mf: this is the first part of the original patch. It is supposed to contain
fixes that are not caused by OpenAL bugs, and thus aren't meant to be
reverted later. The second part will contain a temprary workaround for
OpenAL bugs. Unfortunately, I had to do the split myself as the contributor
refused to do it.
containing slashes, colons and all sorts of evil characters. In Nasal
this could be done via props.globals.getChild("1!@#$//[]{}", 0, 1).setValue(0);
The cause is that getChild() hands the given name directly over to an
alternative SGPropertyNode ("convenience") constructor which sets the
name without any checks.
- unify exception messages: first character is lower case
that interdependencies between sg libs are generally unwelcome, but
sg_exception is a rather basic part, and it's already used by xml, props,
scene, sound and, of course, structure. Since props and xml are core
libs, we can assume that sg_exceptions are available. (OK'ed by Curt)
