to read fonts: only the first character of a whole text is correctly
shown and others are disappeared. I haven't got into the font
implementation so can't explain why this happened and how it should
work under other platforms, but it seems to be fixed by specifying
width and height of the glyph object. The source file is attached for
future developments. At present it just works for my own project. :-)

DAE plugin was linking ORIGINAL images in the Collada file, using image->getName() as a path (even if images were modified in memory!). As the behaviour was not the one of other plugins (3DS, FBX, and such), I made the plugin relativise images filenames (as those plugins) and write the image which is in memory. However, in order to avoid removing features, I kept the previous behaviour but moved it in an option. Here are the options of the plugin I changed:
- daeForceTexture was unclear in this new context and removed in favor of two new options
- daeLinkOriginalTexturesNoForce: Writes reference to the original image if found, instead of writing the image in memory
- daeLinkOriginalTexturesForce: Writes reference to the original image even if not found, instead of writing the image in memory
Of course, if you specify no option, images are written as for other plugins.
Other thing I changed is the UTF8 support as I told you in a previous conversation. Now there is a simple option, "daeNamesUseCodepage", which makes all names except filenames (materials, animation, geometries...) be considered as encoded using current codepage. If so, they'll be converted to UTF8 when writing; else they are written directly. Of course, filenames follow OSG_USE_UTF8_FILENAME as usual.

1. It did not support normals applied to individual vertices.
2. It would only support red / green / blue colour triples, but the pmvs models are generated with diffuse colours. (The PLY format, http://local.wasp.uwa.edu.au/~pbourke/dataformats/ply/, lists specular and ambient colour forms as well.)
To partially overcome these limitations, please find attached modified versions of
src/osgPlugins/ply/vertexData.cpp
src/osgPlugins/ply/vertexData.h
The changes I've made are:
1. I have changed the boolean hasColor flag to a vertexField (which is a boolean operation on an enum) to indicate what fields are present in the ply file. (This is required because Turk's ply reader spits out warnings for every line where you try to read fields which do not exist.)
2. I have modified the code to apply valid normals to either triangles or vertices.
3. I have kludged in "support" for the various colour variants. Specifically, all the colour specified can be read from the file. However, they are all applied in the same way (namely as a colour array, bound to each vertex)."
I have attached a patch, against the trunk from 13:30 today, which consists of the following:
1. CMakeModules/FindOpenEXR.cmake: Look for libIlmThread and libIex as well. 2. src/osgPlugins/CMakeList.txt: Only include the exr subdirectory if both the OpenEXR and zip libraries were found. 3. src/osgPlugins/exr/CMakeLists.txt: Add ZIP_LIBRARY to TARGET_EXTERNAL_LIBRARIES."
The DatabasePager now passes the Terrain pointer into the ReaderWriter's via osgDB::Options object,
rather than pushing a NodePath containing the Terrain onto NodeVisitor. This
change means that the DatabasePager nolonger needs to observer the whole NodePath and
will be lighter and quicker for it.
The change also means that ReadFileCallback can now run custom NodeVisitor's on the scene graph without
having to worry about TerrainTile's constructing scene graphs prior to the Terrain being assigned.
Also changed is the NodeVisitor::DatabaseRequestHandler which now requires a NodePath to the node that you wish
to add to rather than just the pointer to the node you wish to add to. This is more robust when handling scenes
with multiple parental paths, whereas previously errors could have occurred due to the default of picking the first
available parental path. This change means that subclasses of DatabasePager will need to be updated to use this new
function entry point.
Attached is the modified State.cpp file.
I have also attached a sample transcript, showing the new code working properly. I ran it against osgEarth's shaders and it works as expected.

are big enough to handle the primitives used in the geometry.
Added usage of verifyArray into osgfilecache so that it reports any problems on reading files in paged database.
