Hi Martin,
yeah your onboard graphics card is not the fastest ;-) but a optimized
OpenSG build should give you a good speed improvement.

Hi Andreas,
yes, same problem. I have not more than 6 fps and yes I use the Debug
libs of OpenSG. Plus - please don't laugh - my graphics card is a
Intel(R) 82865G Graphics Controller (onboard, I guess). Well, if it's
just a matter of hardware power, I would be satisfied, cause this can
be changed.

Hi,
that's really slow just created a scene with 1000 boxes and 1000
transform nodes (12000 tris, 24000 vertices) I get about 60 fps on my
fx5900. Did you use a debug OpenSG build? This makes a big difference.
I attached my test scene can you load this and give me your frame
rate.

Hi,
I have a rather general question about tweaking performance when
rendering a lot of objects. I have created some kind of grid with
lots
(about 1024) of simple planes with 4 vertices each using the
OSG::Geometry object. Then I created a Node for every geometry and
put
that node under a transform node. So now, I have around 2000 nodes
and
4000 vertices. They are all siblings in the graph. Now when it comes
to
rendering this scene, my program gets awfully slow (around 2 fps).
When
I create a single geometry object with 65000 planes and around
260000
vertices and I render this scene with a single node my program
renders
with around 25 fps or more.
Now, why is this so? Does the traversal of the graph while rendering
really takes that much time? Can this be optimized somehow?
Thanks for your answers. I like to use OpenSG a lot in the future,
but
unfortunatly with a lot of single objects.
Martin
