added frame stamp updating and update traversal to osgViewer::Scene/Viewer.
Updated osgcamera example to use new Viewer API calls instead of using local
rendering calls.
some fix to osgdem.cpp and osgTerrain/DataSet.cpp
These mods should allow to build terrains controlling jpeg compressed
imagery embedded in ive files, using something like:
osgdemd --image-ext jpeg --RGB_24 -O "JPEG_QUALITY 20
compressImageData" ......."
The existing code uses a map with object ID's. The original code only applied the name to a node for a new ID only if the node did not already exist in the map. The problem was that there was another part of the code (when a parent was forward declared) that also created the node with the ID in the map, but it did not know its name. I simply made sure that the name was set regardless of whether or not the node was already in the map. "
--merged with fixes for texture coordinates(is this in CVS/SVN already)?
--changed above mentioned fix output level from osg::NOTIFY to osg::DEBUG_INFO
--added support for VRML97 ImageTextures.
--changed pointers to ref_pointers where possible.
--added format (method separated by "//////") for easier reading."
I have decided to just normalise the drive letter part of file names for the time being and also ensure that names of the format x:/xxxxx are treated as absolute paths. This will cover a lot of cases.
I have raised a bug against collada which hopefully should resolve some others. However there are some pathological cases which I have commented on in the code, these will probably never work properly unless there is a significant rewrite of the daeURI functionality. Hopefully they are rare."
It turned out that nv.getDatabaseRequestHandler() returned NULL; using this pointer to call one of DatabaseRequestHandler's methods is of course illegal.
I patched it by adding: if (nv.getDatabaseRequestHandler())"
From Robert Osfield, reordered the addition of the nv.getDatabaseRequestHandler() check to allow the
default traverse() to be called when no database handling is attached to the visitor.
dxfSection classes, so their members data are correctly deleted.
- changed some methods signatures to pass arguments by reference instead of
by value. The performance and memory usage are enhanced (the reader was
clogging the heap when reading some large DXF files)
The updated files have been compiled and tested with a variety of DXF files
on XP with VS2003, but the changes should not disturb any other compiler."
default Registry Options object, but it would be useful to be able to
request loading with a different Options object. The attached files
allow you to do that (based off the OSG 1.2 source).
For example, I'm implementing a loader that requires context information
when it pages in subgraphs, which becomes significantly complicated when
multiple scenegraphs are requesting subgraph loads with different
contexts (the loader needs to know which context to use, and the
Registry Options needs to be carefully managed so the context settings
don't clobber each other, especially in multithreaded situations). Being
able to pass an Options instance along with the Node request resolves
this problem."
