Hi Johannes,
I presume you mean "pixel buffer objects" rather than "texture buffer

When using PixelBufferObjects in the OSG it's best to just create one

I've now checked in a couple of bugs fixes and some further
submissions since my last call for testing, so could everyone do an
svn update, rebuild and then test the runtime. If things look good
tomorrow morning I'll tag the 2.9.6 release then.
Thanks,
Robert.

Hi Wang Rui,
Sorry for the delay in getting to review your prosed binary format
plugin - I've been trying to clear the rather length backlog of
submissions and bugs... I'm pretty near back ontop of things again and
so look at the next steps beyond the OSG-2.9.6 dev release - and
towards OSG-3.x.
Hi Thilo,
This is may well be a driver issue. Killing the app really isn't a
good way to test things... you can actually get the OSG to
viewer::run() for a limited number of frames then exit using the env
var - set OSG_RUN_FRAME_COUNT to something like 10. i.e.
export OSG_RUN_FRAME_COUNT=10

Hi GuiYe,
You'll need xulrunner-1.8 to compile the llmozlib2 as it doesn't work
with later versions of xulrunner - as Mozilla changed the API in ways
that make porting difficult. llmozlib has now abandoned the gecko
based approach and adopted QtWebKit instead.

Hi Thilo,
So from your description it sounds like "osgviewer cow.osg" crashes
all by itself if left alone long enough, even in SingleThread mode.
This is about as simple an OSG stress test as you could get.
When I do big stress tests I tend run the OSG running overnight

Hi J.P.
The way I'd tackle this would be to have a 1D texture that contains
all the colours, then set up the tex coords on the points so that they
pull the appropriate colour in, then use a texture matrix to update
the tex coords values and to create the animation. Setting the
filtering to neares

I've just tracked the problem down a bug in the new code for

Hi Martin,
By default VPB now creates osgTerrain::TerrainTile's with regular
HeightFieldLayer for the elevation. Are runtime this height field is
then converted using the osgTerrain::GeometryTechnique into a standard
osg::Geometry + osg::StateSet combination, so it does end up being a

Hi Calin,
You can assign a separate DisplaySettings, using
View.setDisplaySettings() to each View(er) that will override the
default of using the osg::DisplaySettings::instance(), you'll need to
do this prior to the viewer.realize() to make sure that the settings
get used in context creation and r
