Hello Holger,
I found a former thread with a quiete similar problem incl. response, to modify
the osg/shader* files. Won't be that easy right?
Well, in the past adding Geometry shaders when these became available
was pretty easy, it indeed just required modifying the Shader header and
cpp, as well as the .osg and .ive plugins to be able to load/save this
new shader type. Adding the two new tessellation shader stages shouldn't
be much more complicated. It's then up to the user to do useful things
with that (until OSG supports shader composition :-) ).
See this changeset for the first checkin of geometry shader support:
http://www.openscenegraph.org/projects/osg/changeset/7776
And you can search from the SVN browser page:
http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph
with terms "geometry shader" to get more information about the evolution
of the code:
http://www.openscenegraph.org/projects/osg/search?q=geometry+shader
If you have the interest and the time, you're welcome to pitch in and
implement tessellation shader support.
J-S
