Hi all,
As presented at the OSG BOF last week, the OSG plugin for COLLADA
v1.4.1 is
available on SourceForge. There is no .zip package yet, you may grab
it from
CVS at http://sourceforge.net/projects/osgdb-collada
Previous versions of the OSG COLLADA plugin were hindered by limited
access to
the COLLADA DOM (document object library) library. The licensing
issues have
been resolved, and the DOM itself is accessible from SourceForge CVS at
http://sourceforge.net/projects/collada-dom
That code is what was demonstrated at the COLLADA social event
following the OSG
BOF last week. For more information, see Andy's OSG BOF presentation at
http://openscenegraph.org/osgwiki/pmwiki.php/Documentation/Documentation
A major new feature is the plugin now implements COLLADA file writing
capability. Using osgconv, the plugin was used to convert Performer
Town from
OpenFlight to COLLADA, which was then imported into Google Earth,
giving pfTown
a "real" location on the globe! ;-)
There is still much work to do on the plugin. The basic geometry
support is in
place, but advanced features such as animation, skinning, and physics
have yet
to be implemented. However, the code is good shape as a solid
foundation for
those further developments.
Sony Computer Entertainment funded Andy to develop the plugin up to
this point
and release it as open source. With that foundational work publicly
available,
it is now time to find another primary maintainer. Please let Andy
or me know
if you would like to take over development.
Great work, I am really interested by the COLLADA file format, and if
I had more time, it would be a pleasure to work on it but now it will
be very difficult. :/
I agree, COLLADA is a really interesting format ant its getting more and
more robust.
I'm currently working for a company to provide smoother workflow from
Maya to OSG- Scenes (for their new VR-System)
Of course I was thinking of Collada and especially now I think it's a
good time to jump on the Collada train.
I'm pretty sure I will have to work a lot on the OSG-Import-side as the
exporter from Maya (www.feelingsoftware.com) seems to work quite good
already.
Anyway, of course I will share my results as far as I'm getting useable
results, but I'm definitely not experienced enough to "take over" the
main-development of the plugin.
I guess one of the first things I want to implement is the binding for
COLLADA_FX - shaders (which are already in DOM 1.4.1-format)
I'd rather implement the shader-stuff using cg/cgfx than with GLSL,
because it's easier to write shaderprofile-fallbacks and to define the
shaders parameters for the artists userinterface already bundled in the
cgfx-file.
But I never really dived into GLSL, so maybe I prefer CGFX/CG just
because I'm used to it... ;)
Still, OSG and Collada is qutie new to me, so it will take some time to
get familiar with both APIs.
Does anybody have experience with GLSL vs. CG in OSG, current state,
support for 1.5 CGFX-files, etc?
(CGFX-files get translated into COLLADA-Format anyway, right?, so, after
that, parameter bindings etc are not a matter of CGFX anymore, right?)

ps: excuse my bad english.... ;)
