Only worked when TMPDIR environment variable had a trailing slash (i.e.
"/tmp/" worked, but not "/tmp").
(Problem shown by simgear's "test suite". It's good to have tests!)
This removes the other still present dependency on osg
in the future sgcore library.
It also remove the need for the NO_OPENSCENEGRAPH_INTERFACE
compile time definition.
Move osg dependent stuff from SGMath into simgear/scene/util/OsgMath.hxx.
Update includes in simgear to reflect this change.
Note that this change also requires an updated flightgear version.
rather than on startup. This will allow changing between winter and
summer textures in-sim, and also allow more interesting regional
textures to be defined.
Better seperation between the rti and the hla level
of classes. Decouple object model setup from the
need to connect at a federate. Fix alignment computations
for the standard hla data types. Work towards an
interaction class abstraction. Add more flexibility in
deriving from the base classes and adding callbacks.
Introduce read{RTI13,RTI1516,RTI1516E}ObjectModelTemplate
methods. Deprecate the current readObjectModelTemplate method
and provide a short term upgrade path.
executing the fgcommand loadxml implicitely untied every previously
tied property if a property type was given in the property element.
That made it impossible to autosave aircraft data for tied properties.
This patch should fix this. It adds an inconsitency, though:
if a property with a given type is read in which has been tied to
before and the property types do not match, the property type in the
xml file will be ignored.
Fixes the more basic probelm of "SGModelLib::findDataFile" resolving an
empty file name to the fgdata (directory) path. findData_File_ should
never return a _directory_ path, only valid _file_ names.
Don't resolve the empty file name, which would result in the fgdata
directory path (instead of a path to a file). Eventually this resulted in
a segfault, partly due to a bug in "osgDB::readImageFile", which reports
"success" when given a directory (instead of a file) path, though it
doesn't return a valid image object.
