HI Sebastian,
thanks for the reply. I also have vegetation generated on the GPU,
works really fine - like 5mil trees on 60Hz. Now I want to try HW
instancing for moving models - your NodeVisitor is good idea to have
any geometry instantiable.
What was your start point? Did you also try the code from the blog I
found or you did it your self? For some reason the code on the blog is
not working and I am struggling to try to fix it since it has really
nice implementation and ideas I am learning now.
I started with the osgforest example

The example I was looking for was in the submissions, called:
[osg-submissions] New example : culling and LODing performed on
GPU side
Unfortunately Robert didn't approve or merge the nescessary
changes. Maybe it went unnoticed.

HI Trajce,
I implemented HW Instancing using the UBO and texture approach
using the osgforest example as a guide.
The majority of the work in my project lied in developing a
visitor making "arbitrary" geometry nodes instanceable.
I also experimented with geometry shader based billboard
instancing, which worked nice for trees etc.
And I do remember some example featuring GPU culling and
instancing, but I cannot find it in the mailing list right now
Hi Community
I found this blog
http://3dcgtutorials.blogspot.de/2013/09/instancing-with-openscenegraph-part-ii.html
and found it very interesting. Although the description is very
well written the code samples seams incomplete and sort of
outdated. Was to ask you if any of you have done some work with
this and is willing to share hints, code snippets?
Thanks a bunch as always,
Nick
