The Texture Pool can be enabled by setting the env var OSG_TEXTURE_POOL_SIZE=size_in_bytes.
Note, setting a size of 1 will result in the TexturePool allocating the minimum number of
textures it can without having to reuse TextureObjects from within the same frame.
Note from Robert Osfield, I've temporarily re-enabled the old focing of of color and depth attachment to avoid regressions on some OpenGL driver. We'll revist this once
we have a mechanism for controlling this override at runtime.
#define FORCE_COLOR_ATTACHMENT 1
#define FORCE_DEPTH_ATTACHMENT 1
Therefore I have changed all the occurances of atof by asciiToFloat or
asciiToDouble.
I believe that it is safe to do so at least for all the plugins.
Included here are also asciiToFloat conversion of environment variables. One
might argue that these should be locale dependent. But IMO these should be
set and interpreted by osg independent of the current locale.

- osg::Texture sets GL_MAX_TEXTURE_LEVEL if image uses fewer mipmaps than
number from computeNumberOfMipmaps (and it works!)
- DDS fix to read only available mipmaps
- DDS fixes to read / save 3D textures with mipmaps ( packing == 1 is
required)
- Few cosmetic DDS modifications and comments to make code cleaner (I hope)
Added _isTextureMaxLevelSupported variable to texture extensions. It
could be removed if OSG requires OpenGL version 1.2 by default.
Added simple ComputeImageSizeInBytes function in DDSReaderWrites. In
my opinion it would be better if similar static method was defined for
Image. Then it could be used not only in DDS but other modules as well (I
noticed that Texture/Texture2D do similar computations).
Also attached is an example test.osg model with DDS without last mipmaps to
demonstrate the problem. When loaded into Viewer with current code and moved
far away, so that cube occupies 4 pixels, cube becomes red due to the issue
I described in earlier post. When you patch DDS reader writer with attched
code but no osg::Texture yet, cube becomes blank (at least on my
Windows/NVidia) When you also merge osg::Texture patch cube will look right
and mipmaps will be correct."
database options like recently added to PagedLOD.
Also there is a change to the traverse method:
The previous ProxyNode checks the VisitorType to be a CULL_VISITOR and the
presence of a request handler to submit a database request.
In contrast to that PagedLOD uses the request handler if it is there - even if
the visitor type is not a cull visitor.
The change removes the cull visitor test from the ProxyNode so that it behaves
like the PagedLOD.
I believe that the presence of a request handler in a visitor might be
sufficient to trigger the requests as this is done in the PagedLOD anyway.
Based on rev 10332."
GL_EXT_framebuffer_blit extension is available. This is due to the early
return from the constructor if this is missing.
As far as I read the standard extension documents, this blit call is not
required to have packed depth stencil fbos.
The change fixes this and allows packed stencil attachments on machines
without the multisample blit command."
constructor issues:
Within the NullStream & NotifyStream classes the base class objects
(ostream) were being initialised before the class member _buffer objects
which they referenced, causing a crash.
I had to move the file scope g_NullStream & g_NotifyStream initialisation
into a function to get them to work.
Also there was a missing osg:: qualifier on getNotifyHandler."
Two implementations of NotifyHandler are currently available:
- StandardNotifyHandler, calls fputs(message, stderr) for severity <= WARN and fputs(message, stdout) for severity > WARN
- WinDebugNotifyHandler, windows users can redirect notifications to windows debug output, notifications can be viewed in output window of the debugger i.e. MSVC or DebugView (http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx) (see screenshot).
I have seen on osg-users that some people do std::cerr.rdbuf(otherStream.rdbuf()) to redirect notifications. This trick will no longer work since osg::notify() returns internal osg::NotifyStream not std::cout or std::cerr. You can use osg::notify().rdbuf(otherStream.rdbuf()) to do this instead.
Additionally I've made some minor fixes:
- Minor imrovements to osg::notify documentation
- NullStream could crash by deleting stream buffer other than default NullStreamBuffer in the destructor i.e. after osg::notify(osg::DEBUG_FP).rdbuf(otherStream.rdbuf())"
Introduced a new callback osgDB::FindFileCallback that overrides the default behavior of findDataFile/findLibraryFile.
Introduced support for assigning ReaderWriter::Options directory to PagedLOD.
Introduced new osgDB::FileLocationCallback for assistancing the DatabasePager to know when a file is hosted on a local or remote file system.
Introduced a new FindFileCallback to Registry to compliement the existing ReadFileCallback and WriteFileCallback.
Added support for assign Find, Read and WriteFileCallbacks to osdDB::Options to enable plugins/applications to override the callbacks just for that
read/write call and any nested file operations
I have attached a fixed file where the traits are checked in the PrimitiveShapeFunctor where appropriate. They are checked for Box, Cone Capsule and Cylinder. These just mirror the checks that were already done in the DrawShapeVisitor.
(another instance where if the ShapeDrawable had just been osg::Geometry, there wouldn't have been a problem... :-) )
I also fixed a small typo in the file in two places ("implementated" --> "implemented")."
