Performance tests on big models did not indicate any performance penalty in using doubles over floats,
so the move to doubles should mainly impact precision improvements for whole earth databases.
Also made improvements to osgUtil::PlaneIntersector and osgSim::ElevationSlice classes
of saving image files inside the IVE file. Currently, only the raw
image data is saved into the file. If your model uses jpg images as
textures then this will cause your file size to increase.
I've added an option that will embed the original image file into the
IVE file. The IVE file will then attempt to read the image from
memory. Since most image loaders support reading from memory, this
shouldn't be a problem. To use this new feature the user must specify
the option "includeImageFileInIVEFile" when converting to IVE.
I tested this out on the "skydome.osg" model that comes with OSG.
Using the old method, the IVE file size would be 785 KB, with the new
method it is only 42 KB.
Also, I've added the support for TextureRectangle's to the IVE reader/writer."
osg::PagedLOD::s/getDatabasePath() and support in PagedLOD::traverse().
osgDB::ReaderWriter::Options::s/getDatabasePath()
osgDB::Input::s/getOptions()
setting of osgDB::Input::setOptions() in ReaderWriterOSG.cpp
src/osgPlugins/ive/DataInputStream::s/getOptions()
setting of src/osgPlugins/ive/DataInputStream::setOptions() in ReaderWriterIVE.cpp
Fixed crash associated with .osg files which contain empty description fields.
From Sondra Inverson, added support to .ive plugin for osgSim::DOFTransform.
