Hi,
I recall a post from some days ago, describing problems with the
llvm-gcc compiler and osg on lion. The app hang/crash on a call to cosf.
The solution was to switch to the gcc compiler.
Perhaps the same issue as yours?
cheers,
Stephan

Hi Michael,
do not apologize for the late answer, as you can see my own reply is
quite late too :)
Talking about the issue, frankly speaking I cannot answer your
questions, the example I sent comes from simplifying some more complex
models that were prepared by character animators, maybe merging
HI Zhen,
In normal OpenGL/OSG usage VBO+EBO's do not take long to create.
Whether osgCuda is the bottleneck or whether it's the crazy number of
primitives you trying to add that might be the problem I can't say. I
havn't used osgCuda myself so can't comment on this specifically.
However, I can
Hi Fred,
The osgQtBrowser example has a code path this creates runs a viewer in
a background thread, this is done to workaround limitations of
threading in Qt. This background thread is an OpenThreads::Thread
rather than a boost one, I don't see why using a boost thread would
cause a particular
Hi Zhen, hi Robert,
You are right Zhen, osgCuda::Geometry always creates vertex buffers br and/or
element buffers. CUDA can only handle this kind of OpenGL geometry. br
However, osgCuda does not introduce any new operation to the implementation
br of osg::Geometry in case you use it in the
Hi Justo,
Take a look to the Variante Shadow Map
algorithmhttp://developer.nvidia.com/node/165 to
apply shadow on the scene.
Instead of use default OpenGL ShadowMap comparaison technique, this
algorithm
provide a different way to capture and apply shadow.
This technique take more resource but

Another issue is missing statistics, probably HUD shader is needed.
No shaders - no hud.
Hi,
I see that the stats HUD does not work in GLES2 and I see this post a few
months old. Did anything change in that area since then?
If not, I will try to find a

Hey.
Thanks Robert for your help.
I just figured out what was the problem. In fact I was calling the constructor
of the osgViewer in a different thread that the viewer.frame() function. This
cause a quite strange issue as the viewer correctly render the scene but does
not response to any

Hi Ulrich,
It is through my own application. What did you pass as arguments to

This sounds very interesting! I've always wanted to be able to create

thank you Robert and David for your answers, I really appreciate them.

Hi Jens，Hi Robert，
I have read the source code of osgCompute and I find my problem is caused by
the large number of PrimitiveSet, not a bottleneck of osgCuda::Geometry.
osgCuda is very good and I will do some research about FEM with osgCuda .
In next step, I will reduce the number of

From web of osgCompute, I find a geometrie's index buffer can be mapped, as
follows:

void* devInd = memory-map( osgCompute::MAP_DEVICE_INDICES );
When I read the source code of osgCuda::Geometry, I found some problem as
Hi Jeremy,
I hope I haven't discouraged you from continuing development on osgWidget! A
native osg gui would have a lot of advantages over an external library. The
main reason I did not consider osg widget was the lack of documentation, so
maybe you can invest some time in that...
