parameter in osg::Image. To support this Image::setData(..) now has a new optional rowLength parameter which
defaults to 0, which provides the original behaviour, Image::setRowLength(int) and int Image::getRowLength() are also provided.
With the introduction of RowLength support in osg::Image it is now possible to create a sub image where
the t size of the image are smaller than the row length, useful for when you have a large image on the CPU
and which to use a small portion of it on the GPU. However, when these sub images are created the data
within the image is no longer contiguous so data access can no longer assume that all the data is in
one block. The new method Image::isDataContiguous() enables the user to check whether the data is contiguous,
and if not one can either access the data row by row using Image::data(column,row,image) accessor, or use the
new Image::DataIterator for stepping through each block on memory assocatied with the image.
To support the possibility of non contiguous osg::Image usage of image objects has had to be updated to
check DataContiguous and handle the case or use access via the DataIerator or by row by row. To achieve
this a relatively large number of files has had to be modified, in particular the texture classes and
image plugins that doing writing.
osgAnimation. It's been tested with the majority of the samples in the
COLLADA test repository and works with all of them either as well as, or
better than, the version of the plugin currently in SVN.
Known issue: vertex animation (AKA morphing) doesn't work at present,
but that's a relatively unpopular method of animating so it's not high
on my priority list."

"I've been informed that the previous DAE submission didn't build on
unix, so here's the submission again with the fixes. Thanks to Gregory Potdevin and Benjamin Bozou.
Also, my apologies to Roland for not crediting his part in making DAE
animation happen, my work was indeed built on top of his work. Thanks
also to Marius Heise and of course Cedric Pinson."
Changes by Robert Osfield, fixed compile issues when compile without C* automatic conversion enabled in ref_ptr<>
and constructor initialization fixes to address some warnings under gcc.
"I have taken the liberty of updating a few files so that there is no longer any derivation from std::vector. I have done this by adding a new file osg/MixinVector and by updating only two others: osg/PrimitiveSet and osg/Array. You will notice that this actually removes what is acknowledged as a \u2018hack\u2019 in osg/PrimitiveSet.
With the original code I did manage to find memory leaks with some compiler options on VC 8 and 9, as well as Intel compiler. I determined the leak existence by instrumenting the destructor code, and by use of a garbage collector as a leak detector (in a similar manner to the Firefox project). Hence in contrast to what I said originally, it is exhibiting symptoms on at least some platforms.
Since I am trying to be a good OSG citizen I got out my editor and started hacking! I have built and tested on Linux (Ubuntu) with GCC 4.x and Windows VC 8 SP1. It appears that nothing is broken, and that I\u2019m using less memory J"
creating subclasses of osg::Array that referenced data
stored an application's internal data structures. I took
a stab at implementing that and ran into a couple of
downcasts in Geometry.cpp. Enclosed is my take at fixing
those along with a simple example of how to do this."
extra pass to doing tri stripping in the osgUtil::Optimzer.
Added validity checks into osg::TexEnvCombine to catch eronous enumarant values.
Improved the efficient of CullingSet's handling of new transforms.
Added a copy shared subgraphs and subdivision code into osgUtil::Optimizer.
