The solution for to refactor the way that events are checked so I add a bool return type to checkEvents() method across osgViewer::GraphcisWindow, osgGA::Devive and osgViewer::Viewer/CompositeViewer classes
Instead of
INCLUDE_DIRECTORIES(${LIBVNCCLIENT_INCLUDE_DIR})
the CMake variable
INCLUDE_DIRECTORIES(${LIBVNCSERVER_INCLUDE_DIR})
should be used.
Attached is a fix for src/osgPlugins/vnc/CMakeLists.txt"
TextureBuffer objects may use osg::Texture::bindToImageUnit(), so GLSL shaders are able to use not only texelFetch() function , but also functions defined in GL_ARB_shader_image_load_store extension : imageLoad(), imageStore(), imageAtomicAdd() etc."
second email: "After a while I found that osg::Texture::applyTexParameters() used with TextureBuffer may cause some OpenGL errors ( applying texture filters and wraps to TextureBuffer makes no sense ) so I fixed it."
I hope the change seems reasonable. I searched the entire code base for code that accesses the StateSetStack, and noticed RenderBin and RenderStage use it. However, I don't think that code would ever be called from within the State::apply() function, so I'm fairly confident the change should be safe."
handle(const PointerInfo&, const osgGA::GUIEventAdapter&, osgGA::GUIActionAdapter&)
returns false.I think it is not correct...i think handled should be changed only when it is really handled."
OSG_DEBUG << "Hello world!\n";
the underlying stream is not automatically flushed. It is flushed
if endl is queued instead of \n:
OSG_DEBUG << "Hello world!" << std::endl;
The notify macros do:
stream->setCurrentSeverity(severity);
return *stream;
So, if a function do:
OSG_DEBUG << "This is a debug message\n";
OSG_NOTICE << "This is a notice message" << std::endl;
the debug message will be classified as a notice message.
It is a problem when the application uses a NotifyHandler. The notify
method of the handler is called with:
severity = NOTICE
message = "This is a debug message\nThis is a notice message"
The attached Notify.cpp contains an automatic flush of the stream when
the current severity changes.
"
If the index is more than the size of _children vector, the new child is pushed at the end of the vector, but the index value is unmodified, so an incorrect value is passed to the "childInserted" method."
1. Respect "noMatrixTransforms" option for matrices attached to meshes, not only those attached to nodes
2. traverse_nodes variable did the exact opposite of it's description.
3. Always try to load referenced textures, even if we can't find the files (in order to the the registry's ReadFileCallback have a stab at it)

See attached my ported code, which fulfills:
- using of setUserValue()/getUserValue()
- user-value will be attached to Geode or Drawable
- actually 3 values will be added: SMC (surface), FID (feature) and IRC (IRcolor). Its UserValue-names are < UA:SMC >, < UA:FID > and < UA:IRC > (without spaces!)
- user-value will be attached to Geode or Drawable
- has an option (named preserveNonOsgAttrsAsUserData) for control whether the UserValues should be attached (Default: no UserValues will be attached)
Reading out this values is very simple. Here is an example (uservalue-name without spaces!):
signed short smc;
if (myGeode.getUserValue("< UA:SMC >", smc))
{
doSomethingWithTheGeodeAndItsSmc(myGeode, smc);
}
else
{
// geode has no SMC
}
