supports compressing the image data. The option to compress the data
is "compressImageData". Currently it uses the jpeg plugin to write the
image. Maybe we could add an option that allows the user to specify
which image format to use. The jpeg writer supports specifying the
quality of the jpeg, so you could use the following command line to
convert the skydome.osg model to IVE using 50% jpeg quality:
osgconv -O "compressImageData JPEG_QUALITY 50" skydome.osg skydome.ive"
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."
with a CoordinateSystemNode which reflect the coordinate system of the
database.
Added support for reading and writing CoordianteSystemNode into the .osg
and .ive formats.
Fixed crash associated with .osg files which contain empty description fields.
From Sondra Inverson, added support to .ive plugin for osgSim::DOFTransform.
value to float, and converted the internal code across to use value_type. This
allows Matrix to be converted to use double's simply by change the definition
of value_type. Added Matrix::glLoadlMatrix and Matrix::glMultMatrix() to
help encapsulate the changes between float and double matrix usage.
Updated code that uses Matrix so it doesn't assume float or double matrices.

"Most relevant news:
1) particle systems now have the "freezeOnCull" property set to false by
default. Since it is an optimization, and using it may cause some unwanted
behaviors if not handled properly, it makes more sense to turn it off by
default.
2) new "LINE" shape mode which uses GL_LINES to draw line segments that
point to the direction of motion.
3) particles can now have a rotation angle and angular velocity.
4) new AngularAccelOperator applies angular acceleration to particles.
5) particle processors such as emitters and programs can have a "start",
"end" and "reset" time coordinate. For example, an emitter may be instructed
to start emitting particles only after a certain time, stop after another
amount of time and then start again.
Update (2) is from Gideon May.
Updates (3) to (5) are from Douglas A. Pouk."
