Hi Andre,
There is nothing I or anyone else can do to suggest how you fix your
problem as there really isn't any where near enough information in
your emails to help us even guess at what the problem. It's like me
telling you I have a piece of string in my hand and telling you that

Hi David,
I really don't know what is up with your usage, there really isn't
enough info about how you set up things to know where things are going
astray.
A window being black suggest to be that rendering itself hasn't
started yet, just that the window has been realized. The osgViewer

I've checked the source code about this,
and after using the nodepath to unproject the 2D coordinates and retrieve the
3d start and end points of the line-intersector, the visit is called like this:
osgUtil::IntersectionVisitor iv(picker);
iv.setTraversalMask(traversalMask);
You may also find that DIVERSE can fill your needs. It's a virtual reality
controller that can be used with osg.

Hi all,
Since Qt 4.4, we are able to mix OpenGL and Qt in a way which provides
more possibility than the osgViewerQT do by using QGraphics framework,
especially for HUD display.
I joint the example I write to do this.
The main function loads a model a display into my QGraphicsScene

Here is code that produces the problem.
I'm building/running on Ubuntu 8.04 with osg 2.4

#include osgDB/ReadFile
#include osgViewer/Viewer

followed by closing one or more of the shown windows and repeating. But
I've not seen any black windows yet. What is the sequence that

Hi Paul,
type view 2 times to get 2 views.
close the first window, i always press 'f' to get out of fullscreen,
type view again.. turns up black.
Maybe this is my driver?
I'm using the default ubuntu Nvidia driver. Also, running Compiz in

Hi Judd,
I have done some work on osgUtil::IntersectionVisitor to add proper
support for Billboards. Could you try out the attached
IntersectionVisitor header/source files and let me know how you get
on. This builds against OSG-2.6/OSG-SVN, but might also compile
against 2.4.

Thanks for much for your quick response, I'll take a look at this and see

After your suggestion and doing a quick Google I saw this post from Rafa

could you please just confirm the this is the way the function is meant to

If so, any idea on how to have my modified osgpick example to work?

I'm not sure what stopping the frame loop refers to, since something like
while(!viewer-done())
{
if (viewer-getFrameStamp()-getFrameNumber() == 500)
{
rootNode-addChild(
osgDB::readNodeFile(some_animation.flt));

viewer-frame();

Not sure if this helps or not, but you have to use the multigpu option
with the 7950GX2, not the sli option. multigpu is for SLI with two

Hi Max,
My guess is that your Viewer's SimulationTime is up and running by the
time the new model is loaded, rather than starting off at 0.0 which is
causing the problems.
The actual implementation details of osg::Sequence is something that

I have added a method called set (did not know what to call it) that
allows you to set the start and end points for the LinSegmentIntersector
using the CooridnateFrame and the x, y values like one of the
constructors does. It just makes it easier to reset the start and end
points

Setting multigpu did nothing either.

To test it, I modified the osgpick example (attached) to pick, for instance,

Have you tried setting it to using display lists instead of vertex arrays? If
they don't suit, then you may be able to figure out what card you are using,
or make some sort of configuration check in an installer then set the
environment variable?

HI Shayne,
Most modern machines regarless of OS should performance pretty well on
osgdem generated databases. However, you must compile the OSG under
release mode. Could this be the problem?

We had similar issues with terrain recently. On windows it was single
digit framerates and the same database on Linux was 30 fps but %100 on 2
cores. Rebuilding our terrain without the -terrain flag solved the
issue. Framerates on windows jumped up to 30 fps, Linux to 60 fps with
%30 on 1 core.

That's odd. If you set it to use Display lists, it should override the
settings on the database pager so that it only uses display lists, and not
VBO's. Do you thing they are broken for the 945 too?

My thought is that the override only applies to nodes that are paged
in. The root node of the scene is still using vbos as far as I
understand since of doesn't have to be paged in.
