This makes it possible to redefine the viewing direction of 'home' in the other manipulator - so home in a GIS app could be a plan view.
Since _homeUp is set to (0,0,1) and no current code changes it there shouldn't be any difference for current users."
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())"
The changes are more or less just beautifications
(when looked at them from the C++ view), but make
wrapping OSG with SWIG easier.
I have tested the changes with both 2.8.1-rc4 and the
current head and would appreciate to incorporate the
changes in both branches.
Here is a description of the changes:
osg/BoundingSphere:
Use the following typedef (like used in BoundingBox)
typedef typename VT::value_type value_type;
instead of
typedef typename vec_type::value_type value_type;
SWIG reports errors on the latter construct.
Also makes it consistent with BoundingBox.
osg/Vec4ub:
Consistent use of "value_type" throughout the file.
osg/Vec?b:
Consistent use of "value_type" throughout the files.
Also changed
typedef char value_type;
to
typedef signed char value_type;
In the case of a simple "char", SWIG assumes a string.
Using "signed char" instead of "char" does not change
the behaviour of the class.

implementation of GraoicsWindowCocoa:
Enhancements/Bugfixes:
+ now it's possible to integrate osgViewer better into existing
cocoa-applications:
* create one or more NSOpenGLView(s) and add these to your window(s)
* create one or more NSWindows
* disable the integrated event-polling of osgViewer, and let the work be
done by Cocoa / NSApplicationRun. You'll have to run the osgViewer's
runloop in a separate thread
+ missing menu-event-handling implemented
+ added NSAutoReleasePools where necessary, this fixes some memory-leaks
+ fixed some crashes and thread-issues"
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
Original email from Frederic at start of thread:
"he patch attached, made from r10068, fix two things, in other of importance :
- the selected cursor is never shown ( second change in file ). Only the left arrow is always displayed.
- remove the arbitrary ( in my sense ) limitation that the user cannot choose a cursor with the same shape that one used when resizing the window. This limitation doesn't exist for X11, and we have a diverging behaviour there ( first change in file ). Flightgear use the LeftRightCursor in look around mode."
Follow up email from Frederic (with changes that finally made it into this check in:
"I've just tested Mark's suggestion and it works perfectly, even when the
cursor goes to the border then come back inside the window.
But his patch doesn't seem to be based on the last revision of the
files, or at least not on the trunk, and there are more changes than
expected in them, including some loss from the previous patches.
The patch attached is based on r10068 of
src/osgViewer/GraphicsWindowWin32.cpp and r10067 of
include/osgViewer/api/Win32/GraphicsWindowWin32"
Converted Present3D across from using libxml2 to using the new osgDB::XmlNode/XmlNode::Input classes from Xml Parsing.
This changes removes the dependency on libxml2, and allows the present3D application and p3d to work on all platforms.

The change is source compatible with current osg code and will not affect current users, it simply adds an additional parameter to the GraphicsWindowWin32::WindowData struct constructor and defaults to the current behavior.
Attached are the files "include/osgViewer/api/Win32/GraphicsWindowWin32" and "src/osgViewer/GraphicsWindowWin32.cpp" with my changes, based on svn revision 10045. In addition, I have provided an svn patch file with the same changes for your convenience.
I have discussed the matter with my supervisor, and agreed that my company makes no copyright claim over this extremely trivial change (or to put it another way, we assign copyright to the open scene graph community.)"
TrackballManipulator. The purpose of this is to disable throwing when
you release the mouse button while moving the mouse. The default
settings is true (ie, allow throw). The two source files are attached.

Background: when you access a file over HTTP, you cannot rely on a file extension being present; instead the file's mime-type is conveyed in the HTTP Content-Type response header. This facility adds a mime-type-to-extension map to the registry to handle this.
There are two new osgDB::Registry functions which are pretty self-explanatory:
void addMimeTypeExtensionMapping( mime-type, extension )
ReaderWriter* getReaderWriterForMimeType( mime-type )
I also added the file osgDB/MimeTypes.cpp which houses a hard-coded list of built-in types. I took the list from here (http://www.webmaster-toolkit.com/mime-types.shtml) and then pared it down to include mostly image and video types, editing them to map to existing plugins where possible.
In addition, I updated the CURL plugin to a) install a set of built-in mime-type mappings, and b) use them to look up an extension in the event that the target filename does not have an extension.
Here is a test case. This URL pulls down a JPEG (without a file extension):
osgviewer --image "http://us.maps3.yimg.com/aerial.maps.yimg.com/ximg?v=1.8&s=256&t=a&r=1&x=0&y=0&z=2"

to make is easier to write code that can work on DrawElementUByte, UShort or UInt.
Changed the osgTerrain::GeometryTechnique so that it automatically chooses
the use of DrawElementUShort or DrawElementsUInt accordining to the size of the tile.
Very simple cases of state configuration are supported (all the ones I really need):
- single per pixel not attenuated non spot light source ON/OFF
- exp2 fog ON/OFF
- diffuse texture in rgb + optional specular gloss in alpha (Texture unit 0) ON/OFF
- normal map texture (Texture unit 1 and Tangent in VertexAttribArray 6) ON/OFF
- blending and alpha testing (not in shader pipeline)
To view fixed function pipeline files and paged databases simply run >osgshadergen myfile.osg"
