Hello all, I've been seeing a problem with high CPU utilization when

Hi Ulrich,
Sorry about the lack of system specs.
I'm actually using an NVIDIA 7950 GT with the latest drivers.
Some other system specs:
AMD FX-62 Dual-Core
Vista 64-bit
If it matters any, I'm using the SVN build of OSG.
Thanks for the help.

Hi Kim,
The high CPU utilization in this case clearly isn't the OSG, but the
drivers/OS.
Try a different OS/drivers. Also once you home in what combination causes
the high CPU utilization go pester NVidia about there driver doing a
spinlock.

Hi Kim,
Update on the linux bug issue with the squary waves.
Two days ago i compiled the osgOcean v1.0 (not the repository) and i

Hi,
I'm using AnimationPathCallback to animate an object. It works well.
Now I like to return to the initial position. How can I do it?
I have tried with reset() method but it don't give me the hoped results.
Thank you!
Cheers,

Hello,
osg use the std::cerr for the error output and i think it is not so
good. I get the error in the console every time.
Nvidie PhysX use a class NXUserOutputStream. It is a nice idea for
osg, maybe?

Hi!
I'm working with OpenSceneGraph 2.8 and I'm wondering how to install osgPPU.
I have been to the wiki but I find something about Trac and not osgPPU so I'm
lost. http://projects.tevs.eu/osgppu/wiki/TracInstall

Hi,
I have built a geometry in which I have defined vertices, faces, normals per
face and color per vertex.
When I use this code in a simple openscenegraph progam with only one node (the
geometry) the rendering is perfect.
But, when I use it in my application scenegraph, the color is

Mixing per face/per vertex like this causes OSG to fall back to slow
OpenGL paths (glBegin and friends). Please try using normals and colours
per vertex.
Hi Robert, hi folks,
The input data I currently have is a regular grid with holes. At the
moment support for irregular meshes is not needed. All mesh

Are you able

thanks for the link. I already took a look at this project. It really
looks impressive.
Currently, all my data is based on regular grids. If it is possible to
tag all lattice points of the grid which are located in holes, I could
get rid of them later in the geometry shader. In this

Hi,
Iam testing the osgPlugin gecko to embed a browser window to my osg world.
I need events from the browser when the url has changed, for example,
a user clicked on a link in the browser window.
Normally, the function NotifyInvalidated (class
LLEmbeddedBrowserWindow) should be called.

Hi Miguel,
It' sounds like lighting or material properties aren't set up correctly, or
perhaps your geometry isn't complete in some way.

Hi Nils,
To get events back from underlying browser it would probably be best to go
with using QWebKit based embedded browser rather than the existing
gecko/llmozlib plugin that I wrote last year. QWebKit is far more amenable
to getting various events back, although not perfect it's turned out

Using the osg simplifier on a geometry, I'm just surprised to see that there
is no way to set a level of simplification or something like that.
Maybe I didn't saw it, but for the moment I just found
