Changes to existing files:
ReaderWriter.cpp -- to support writeNode() of course.
ReaderWriterATTR.cpp -- to support writeObject -- we write .attr files for textures, if they don't already exist.
AttrData.cpp/.h -- Minor fixes.
CMakeLists.txt -- to include the new files in the build."
From Robert Osfield, port to non Windows platforms just required fixing of header capitilization errors
that windows lets through the net due to having a case insensitive file system.
The files are:
include/osgSim/ObjectRecordData -- The new class. Derives from Object to support .osg IO.
src/osgPlugins/OpenFlight/PrimaryRecords.cpp -- Reads data into that class.
src/osgPlugins/osgSim/IO_ObjectRecordData.cpp -- .osg IO support."
From Robert Osfield, made the OpenFlight read object record data optional via the -O readObjectRecordData ReaderWriter option.
completed the new registration of the plugin-readerwriters
("REGISTER_OSGPLUGIN") according to your osgstaticviewer-example (see
attachment, based on today's svn)."
the specification. With these mods, blink sequences are now created for
flashing light point nodes, either palletized (v.15.8 and later) or
non-palletized (15.7 and earlier). Thanks to Brede for his
implementation of the palletized light point nodes.
There is still work to do on adding the capability to properly handle
light point system nodes, but this does add some capability that did not
previously exist. So, I wanted to at least submit this and I will
hopefully provide the additional capability in the near future.
I've tested the code modifications with Visual Studio 2005. I don't
have the means to test any other operating system, but I would suspect
that there shouldn't be any issue (famous last words). I used the test
files that I uploaded to the users forum to test the changes.
In addition to the added capability, I changed the light point node
radius to the "actualPixelSize" value in the file. Previously, the
radius was set to half the actual pixel size (see
LightPointRecords.cpp). Not sure why this was the case. But, it was
brought to my attention by a co-worker who created the OpenFlight files
and was testing them with different viewers. If there's some history
for setting the radius to half the size, then this change can be
omitted."
The cache works for nested externals but is cleared before the master
flight file is returned. I implemented texture caching using the same
mechanism."
ignores the Object records if it's safe to do so. The reader option
preserveObject prevents this optimization.
I have also removed the flat shading attribute set by the Object
record. This flag is only intended for the "Calculate Shading"
operation in Creator."

I use this for optimized preprocessing of large databases what can not

in one pass because of memory limits."
"I found some artifacts on some models and traced it back to the
external palette override feature. There are some changes in the
layout of the external record the loader have to take into
consideration.
The other fix is to remove the OF pools from the user data of the
external ProxyNode when it is no longer needed."
"Previously, the new OpenFlight plugin only allowed ext ref models to use
their own palettes. With this change, parent models can override child model
palettes with the parent palettes.
These changes are made against very current CVS (just updated about 1/2 hour
ago, eliminated conflicts, and retested before this posting).
To regurgitate what I did:
A new class, ParentPools (public osg::Referenced), is created when an ext
ref record is parsed, and it is populated with any parent model pools that
should override the child model pools (according to bits in the ext ref
record). The ParentPools object is then set as UserData on the ProxyNode
corresponding to the ext ref.
When the ReadExternalsVisitor hits the ProxyNode, it takes its UserData and
sets it as UserData in the Options parameter to the osgDB::ReadNode call,
which then read the ext ref model. In the course of parsing the Options
string, ReaderWriterFLT also looks at the Options UserData and sets the
parent pools in the Document class accordingly.
When palette records are encountered while loading a file, they are ignored
if the corresponding pool was set by the parent.
Thanks to Brede for consulting with me on the implementation.
"
From Robert Osfield, remapped Paul Martz's changes to Pools.h and PaletteRecords.cpp w.r.t texturePatternIndex being a in16, and converted a char* string to a std::string.
"- Replaced some member attributes with local variables in Face record.
- Multitexture support in Vertex class.
- Renamed VertexList to VertexListRecord (VertexList is now a Vertex array)
- new Mesh (with reserved field at offset 12, thanks to Paul Martz)
- new LocalVertexPool
- new MeshPrimitive
- Use ProxyNode for externals.
- Local cache for externals"
that removeChild(Node*), removeChild(uint) and equivilant Geode methods are
now inline methods, not designed to be overriden, and seperated out the
multiple remove method to be called removeChildren(uint, uint) which is
now the only virtual method. There removeChildren is now the method to
override in subclasses.
This reorganisation requires some call code to be rename removeChild usage
to removeChildren.
