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.
* Change OcclusionQueryNode::getPassed to take a NodeVisitor rather than the distance from BS center to the eye point. Change where CullVisitor calls this method to use the new parameters.
* getPassed now exits early and returns true to avoid blinking / blink-in of geometry for the first frame or for out-of-range LOD children coming back into view.
* getPassed now considers the distance from the near plane to the bounding sphere (rather than eye point to bounding sphere) when determining if the viewer is "inside" the bounding sphere or not."
which utilises a global recursive mutex that is dedicated to manage Observer and ObserverSet.
The new global mutex for observers avoids problems with deadlocks that were occurring previously when
an osg::Refenced object was being deleted at the same time as on osg::ObserverNodePath.
the extra capability of making it possible for Observers to assume ownership of a object that would otherwsie be deleted.
Added a thread safe ref_ptr<T> observer_ptr<T>::lock() method for robust access to an observed object. This
makes observer_ptr<> more equivilant to boosts weak_ptr.
Introduced the OSG_NOTIFY_DISABLE Cmake variable + include/osg/Config #define to control whether the OpenSceneGraph build
should disable the notification system completely. By setting OSG_NOTIFY_DISABLE to ON in CMake and then rebuilding the
the OSG you can get a slightly smaller (~1%) and more slightly efficient library which can be good for shipping applications,
but with downside of reduced ability to detect runtime problems and their causes.
From Robert Osfield, I didn't merge the change of parameter type of IntersectKdTree::intersect() as the internal maths is all done in Vec3s. Keeping Vec3 here hasn't effected the test results.
osg::Texture1D classes, for the reason of implementing the I/O
serialization feature. In the Sequence header, I've added some more
convenient functions: setTimeList/getTimeList,
setLoopMode/getLoopMode, setBegin/getBegin, setEnd/getEnd,
setSpeed/getSpeed and setNumRepeats/getNumRepeats.
In the Texture1D header, fixed:
inline void setTextureWidth(int width) const ...
to:
inline void setTextureWidth(int width) ..."
Notes from Robert Osfield, have gone a little further with these changes and have removed some of the original get methods that were out of step with the way the rest of the OSG manages the set/get property pairs.
1) Add getShadowComparison() accessor function to osg::Texture class
2) Modify ReaderWriterTiff::writeTifStream() and _readColor() (in Image.cpp) to handle pixelFormat==GL_DEPTH_COMPONENT as if it were GL_LUMINANCE
3) Modify the Texture classes of the ive and osg plug-ins so that they save/load the following Texture members: _use_shadow_comparison, _shadow_compare_func and _shadow_texture_mode
"
glActiveTexture on every State::apply after more than one texunits have been
used.
This is against 2.9.6 (I think SVN head is the same)
Quick Synopsis:
New functions:
State::applyModeOnTexUnit
State::applyAttributeOnTexUnit
State::applyModeMapOnTexUnit
State::applyAttributeMapOnTexUnit
State::applyModeListOnTexUnit
State::applyAttributeListOnTexUnit
All copies of the normal versions, but they also set the active tex unit if
absolutely necessary (i.e. only if they call something OpenGL).
State::apply (*2)
State::applyTextureAttribute
Changed to call the above functions and no longer call setActiveTextureUnit
themselves.
State::setActiveTextureUnit
Made inline, so the benefit of having applyModeOnTexUnit (etc) inline
is retained.

To enable the automatic attachment of the required update callback to call osg::Image::update(..) subclasses from osg::Image will
need to implement the osg::Image::requestUpdateCall() and return true, and implement the osg::Image::update(NodeVisitor*) method to recieve the update call during the update traversal.
