facilitate the subclassing of Image providing interactive behaviours so as
used in the vnc interactive VncImage class.
osgViewer::InteractiveImageHandler provides an event handler that convertes osgGA
mouse and keyboard events into the coordinate frame of an image based on ray intersection with geometry in
the associated subgraph.
Changed the ordering of events processing in Viewer and CompositeViewer to allow
scene graph event handlers to take precidence over viewer event handlers and camera manipulators

function FltExportVisitor::writeExternalReference( const osg::ProxyNode& proxy ):
Line 423 in file expPrimaryRecords.cpp has to be changed from

to
const ParentPools* pp = dynamic_cast<const ParentPools*>(proxy.getUserData() );
"
The semantic change that went into the ac loader with the past patch was
incorrect wrt the document describing the behaviour of ac files and
inconsistent with what ac3d itself displays for that files.
This attached change reverts the behaviour to the original one. The
infrastructure to change this is left in place.
The change is based on rev 9045."

and a later post the same osg-submissions thread:
"it's been a while since I have made the changes but I think it was due to problems with static builds of OpenThreads on windows. I was using
OpenThreads in a communication/synchronisation library (without
OpenSceneGraph). It seems I forgot to post a small change in the CMakeLists file of OpenThreads. If a user turns DYNAMIC_OPENTHREADS to OFF (static build) OT_LIBRARY_STATIC will be defined in the Config.
Without these changes a windows user will always end up with a "__declspec(dllexport)" or "__declspec(dllimport)" which is a problem for static builds."
And another post from Blasius on this topic:
"I tested with VS2005 and VS2008. For 32 bit everything works as expected. For x64 and VS2008 I could successfully do the cmake-configure and then the compilation but I had occasional crashes of cmTryCompileExec.exe (during the cmake-configure phase) which seems to be a cmake bug. With VS2005 and 64bit cmake does not set _OPENTHREADS_ATOMIC_USE_WIN32_INTERLOCKED although the interlocked functionality should be there. If I place the source snippet from the CHECK_CXX_SOURCE_RUNS macro to a separate sourcefile I can compile and run the resulting executable successfully. Forcing OPENTHREADS_ATOMIC_USE_WIN32_INTERLOCKED (on VS2005/x64) reveals a bug in "intrin.h" which seems to be fixed in VS2008 but not in VS2005.
In case anyone is interested the lines:
__MACHINEI(unsigned char _interlockedbittestandset(long *a, long b))
__MACHINEI(unsigned char _interlockedbittestandreset(long *a, long b))
__MACHINEX64(unsigned char _interlockedbittestandset64(__int64 *a, __int64 b))
__MACHINEX64(unsigned char _interlockedbittestandreset64(__int64 *a, __int64 b))
should be changed to:
__MACHINEI(unsigned char _interlockedbittestandset(long volatile *a, long b))
__MACHINEI(unsigned char _interlockedbittestandreset(long volatile *a, long b))
__MACHINEX64(unsigned char _interlockedbittestandset64(__int64 volatile *a, __int64 b))
__MACHINEX64(unsigned char _interlockedbittestandreset64(__int64 volatile *a, __int64 b))
The worst thing that can happen is that interlocked funtionality is not detected during cmake-configure and the mutex fallback is used.
Which reminds me another small glitch in the Atomic header so I attached a corrected version.
Why is the OT_LIBRARY_STATIC added to the config file? It is not needed anywhere.
OT_LIBRARY_STATIC is needed if you are doing static-builds on Windows. See my previous post on that.
"
MSVC_VERSIONED_DLL, NMake makefiles and CMake 2.6.2.
The compilation fails because it tries to copy ot11-OpenThreads.lib to
OpenThreads.lib which is valid for the 2.4.x era of CMake but not
anymore in 2.6.x era.
The provided file from the CMakeModules directory adds a tests on the
CMake version and corrects this. Works for me now."
- Matrix transform nodes were stripped out, and the
vertices and normals of each node were
transposed by the modelling matrix. My change preserves
the matrix transform nodes, so that
models can still be articulated by changing the matrices.
- Lights were copied from the COIN scenegraph to the OSG
scenegraph, but they were not associated
with a LightSource node. My change for this creates a
Group and adds a LightSource for each Light.
- If VRML textures have names, the name is now copied to

a capping the number of PagedLOD to a sepcified maximum, with pruning of inactive
PagedLOD when the total number of inactive and active PagedLOD goes above the maximum.
To enable the mode set the env var OSG_MAX_PAGEDLOD to a value something like 1000.
