Hi Robert
Perfect, i will help you in analyzing the performance bottle neck. of course
the kd-tree will be an imporant new feature, and also new rendering technics
could become reasonable once we have a really fast framework for
intersection tests.

Hi Nolan,
You have a couple of options for reducing the elevation resolution,
either use the command line option
--tile-terrain-size size
It defaults to ta size of 64, so reduce this to something like 16.
The other route is to use the --terrain option and at runtime vary the
sampling by

Hi Robert,
i tested the whole afternoon with a really big terrain database (city of
cannes). i rebuild our internet based visualisation plugin with latest
openscenegraph (SVN of this morning) and the performance with
the kdTree datastructure enabled is much better than with elder OSG version.

Hi Adrian,
It's great to hear you getting better performance. How much is down
to more efficient intersections vs other changes to the OSG I cannot
say - you'd need to profile the relative costs of intersections/cull
and draw traversals etc.
KdTree are only used in intersections, so it doesn't

Hello All,
Is there a way to use image maps with some of the other material properties,
like emission or specular or diffuse? I am working on adding some
functionality to the LWO reader. We have been able to get the transparancy

Hi J-S, et. al.
When you mention caching the intersect visitors, when should you use reset()
and when are setStart()/setEnd() used?
In my game, I keep simplified, bounding box representations of the ships in
the scene and then do line segment intersections. When I do the
calculations, I start
I decided to go down the route of writting my own line, circle etc
algorithms as I only need a few, but I have hit a slight snag. :-( I have
attached an image to show the effect I am getting, ideally I would like the
Texture2D which is projected onto the billboard to be sharper? I.e the lines
multi translucent geometry with equal depth but alpha value is not equal.
when i render these geometry ,i can not see all geometry! Why ?
Can everyone give me some advice!
Thanks!
