implementation of AtomicCounterBuffer based on BufferIndexBinding
add example that use AtomicCounterBuffer and show rendering order of fragments,
original idea from geeks3d.com."
Without the change the application does not work properly. First I get the notification that an OpenGL error occured. After some more of this error messages I see broken textures on the screen. With the changes attached to this message my application works as intended."
Note from Robert Osfield, changed the Image::supportsTextureSubloading() to be const and to be implemented in the .cpp rather than inline.
working on some junk low-end graphics cards which I still have to
support. They worked ok with osg 2.8 and earlier.
The problem turned out to be with gl proxy textures, which are
unreliable on those devices. Proxy textures are used by the glu
mipmap build routines to determine if a texture size is
supported. The external glu library had a nice fallback
behaviour, so that if proxy textures didn't work then the mipmap
texture was still created. But in the work on the new embedded
glu routines that fallback behaviour has been inadvertently
lost. I have restored the fallback in
src/osg/glu/libutil/mipmap.cpp. It doesn't add any extra
complexity."
Copying user objects was missing."
Note from Robert Osfield, in submission changed
_objectList.push_back((*itr)->clone(copyop));
to
_objectList.push_back(copyop(*itr));
I found that some of the items that had been paged in were being expired on the first frame that they were not visible (as the cache was full). This resulted in excessive paging every time the view was moved. With the following changes I could only allow children to be expired if they had not been used for e.g. 30 seconds or 60 frames."
between the contexts, using the GraphicsContext::Traits sharedContext
and setting the same contextID.
When one of these shared contexts is closed, GraphicsContext::close
deletes all GLObjects for that contextID, regardless of the fact that
they are shared. This means that all of the other contexts sharing the
objects have to recompile them.
The attached tweak makes GraphicsContext::close a bit less brutal for
shared contexts. I have also changed a misleading diagnostic message.

This patch add "FirePro" to the black list of renderers in State.cpp / initializeExtensionProcs
It allows to avoid an OpenGL error on Viewer initialization.
Tested on FirePro M7740 / Windows7 x64 Driver 8.85.7.2"
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.
Motivation ;
When using PagedLODs, you don't always know the real size of loaded children,
If it occurs that they are out of predefined bounds, picking on the parts that are out of bound will fail
They also can be culled out too soon.
The problem often occurs with long object (roads).
I've modified LOD and ProxyNode to include this option."
and later email:
"Attached the UNION_OF_BOUNDING_SPHERE_AND_USER_DEFINED version
There are impacts on some serializers (dae, osgWrapper).
I haven't modified deprecated osg, since it's deprecated"
So with the 3.0 api change we propose the following change:
- put OSG_EXPORT on the QueryGeometry class so that we get access to the getNumPixels method.
- Create a function called getQueryGeometry that returns a casted _queryGeode->getDrawable(). Or a function called getQueryGeode that returns _queryGeode."
same behaivour across platforms, something that can be achieved now thanks to the integrated GLU library.
Corrected the default of the ResizeNonPowerOfTwoHint to true to reflect the actual default setting set by the
Texture default constructor.
_isTextureBorderClampSupported is set to "TRUE" in Texture.cpp, because of the version number check (GL VERSION >= 1.3).
This leads to an invalid enum error, when GL_TEXTURE_BORDER_COLOR is tried to set.
