Hi Folks,
First off, let me say that it's good to be back on the list - it has been
awhile ;-)
I'm trying to tune a scene-graph representing a relatively-large model. I'm
seeing what I think are abnormally long cull-traversal times. The SG looks
as follows:
(State is constant across the entire
orms. So try out the SVN/trunk or 2.7.x developer releases.

Thanks. Is there a primmer on osg::KdTree anywhere?

Hi All,
OSG 2.7.4 - I'm seeing a reversed normal when running
osgUtil::SmoothingVisitor on a drawable containing only tri-strips. Not
sure if it is the first or last vertex, but I've repeated it with several
different examples.
Has anyone else seen this?

Is there a way to load files from a byte-buffer? I'd like to be able to
store certain shape-files as resources and load them with something similar
to:
osgDB::readNodeFile(shapeFile)
something like:
osgDb::readFromByteBuffer(char *buffer, size_t size);
I can't find anything like this in the AP
Hi Gang,
I'm working on some code where it is desirable to share vertex & normal
arrays across multiple drawables (these are osg::Geometry's), *and* to allow
each drawable to have its own unique color (BIND_OVERALL). My thinking is
that this can be done using VBOs, but I cannot find any good exam
Hi Gang,
I'm working on improving picking performance via KDTree, but I'm hitting an
issue that is driving me nuts: If I pick a node from directly above (e.g. +
Z axis) everything works great, and picking is *very* fast. If I pick at an
angle, (e.g. from eye(1,1,1)) then picking is fast, but not
pick then this will make it easier to track

Does this make any sense?

Hi J-S,
Try this:
void QOsgScene::drawBackground ( QPainter * painter, const QRectF & rect )
{
if (m_redrawEnabled == false){
return;
}
emit aboutToDraw();
// Only works with OpenGL
if( painter->paintEngine()->type() == QPaintEngine::Open
Hi Osg-Users,
Here's a topic that I cannot seem to find any reference in the archives for.
I'm trying to create an Axes rotation indicator Glyph in the lower
left-hand corner of our viewer (X, Y, Z). I've got working code for this
(see below), but it is an orthographic projection, while my scene
This may be a simple question - is the LOD range distance specified in
object or world coordinates? I seems as if it should be in world
coordinates, but I've got an example with numerous LOD nodes in sub-graphs,
and if I sent a constant distance range in each of them (0.0, 30.0f) so that
each LOD

cheers,

, in order to accomplish what I'm after, I'd need a mechanism to
allocate the underlying array on a 16 byte boundary. It looks as if
this should be easily doable as MixinVector is a std::vector. Any
thoughts on this?

Hi Everyone,
Working off the OSG trunk this afternoon, I tried some experiments
with VertexBufferObjects and our geometry (all on the fast path). The
only deltas in our code are as follows...all timing as measured by OSG
stats:
geometry->setUseDisplayList(true)
geometry->setUseVertexBufferObject
me try and
duplicate the issue outside our app.
cheers,
sean
