With this support, users are able to include additional information in their models. Additionally, tools such as sketchup that support asset tags use the values appropriately within their imported models."
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.

Mathieu Marache, he added the last missing piece to this puzzle.
I think it is safe to commit these changes to trunk, as the traditional
way via dylibs should work as before.
Here's some more info how to get frameworks:
With these modifications it is possible to compile frameworks on OS X,
when you set the Cmake-option OSG_COMPILE_FRAMEWORKS to true. If you
want to embed the frameworks in your app-bundle make sure to set
OSG_COMPILE_FRAMEWORKS_INSTALL_NAME_DIR accordingly.
You'll have to build the install-target of the generated xcode-projects
as this sets the install_name_dirs of the frameworks and plugins."
osgAnimation. It's been tested with the majority of the samples in the
COLLADA test repository and works with all of them either as well as, or
better than, the version of the plugin currently in SVN.
Known issue: vertex animation (AKA morphing) doesn't work at present,
but that's a relatively unpopular method of animating so it's not high
on my priority list."
Follow up email:
"I've been informed that the previous DAE submission didn't build on
unix, so here's the submission again with the fixes. Thanks to Gregory Potdevin and Benjamin Bozou.
Also, my apologies to Roland for not crediting his part in making DAE
animation happen, my work was indeed built on top of his work. Thanks
also to Marius Heise and of course Cedric Pinson."
Changes by Robert Osfield, fixed compile issues when compile without C* automatic conversion enabled in ref_ptr<>
and constructor initialization fixes to address some warnings under gcc.
-Changed the addition of lights to add the lightsource directly into the scenegraph (instead of below a switch node)
-All added lights are enabled in the root stateset and replace the head- or skylight.
(if no lights are available the head- or skylight will remain active)
-Ambient in osg::LightModel is zeroed out. All ambient now comes from separate ambient only light sources.
-Lights can now be written properly
-Replaced strings by constants defined in the Collada DOM"
New features
+Read and write of osg::LOD, osg::Switch, osgSim::Sequence, osgim::MultiSwitch and osgSim::DOFTransform data in <extra>
+Read and write of osg::Node description data in <extra>
+Plugin option "NoExtras" to prevent writing of <extra> data and only traverse the active children when saving
Changes/additions
+instanced_geometry and instanced_controller are now loaded in a single Geode with multiple Geometries instead of multiple geodes with a single Geometry
+Changed all calls to the deprecated createAndPlace() to the new add() methods
+All transformation elements <scale>, <rotate>, <translate>, <lookat>, <matrix>, <skew> are now concatenated properly in to a single MatrixTransform.
Previously this was not done in order as required by Collada and and not all elements were included.
+Complete skew matrix creation
+Automatically add GL_RESCALE_NORMAL if scale is non-identity
+Blinn shininess remapping to [0,128] when in range [0,1]
+Changes to CMake file to make it compile on Windows
+Coding style and code documentation
Bug fixes
+Transparent texture writing fixed
+Fixed bug in using osg node name as collada node ID
+Fixed usage of double sided faces in GOOGLEEARTH extra
+Not adding blendfunc and blendcolor when opaque
TODO/Wishlist
-solve differences in drawables, DAE reader should place multiple collation elements into multiple primitivesets in a single geometry where possible (only when same material)
-solve differences in matrices
-multitexture support
-skinned mesh and generic animations using osgAnimation
-profile_GLSL based on COLLADA OpenGL Effects Viewer http://ati.amd.com/developer/rendermonkey/downloads.html
-handling more <extra> to more closely mimic the intended lighting"
1. DAE object no longer held onto by plugin.
2. Filename to URI conversion now handled internally by plugin.
2. User can supply an external DAE object for use by the plugin.
3. User can supply a std:string object for the plugin to return the URI of
the document just processed.
4. User can supply a std::string to receive the unit name information from
the document just read in. (e.g. meters, inches, etc.)
5. User can supply a float to receive the metric conversion factor from the
document just read in.
6. User can supply an enum to receive the up axis orientation information
from the document just read in.
7. Material transparency can be both read and written.
8. User can supply an experimental GoogleMode option on output. The plugin
will try to emulate the way Sketchup specifies transparency (i.e. the
inverse of what it should be!). I am still struggling to get GE to
understand transparency, anyone know what it expects?
9. Rudimentary support for Collada effect parameters (newparam, setparam,
param) on input. Basic nVidia FX Composer dae documents can now be read.
