Hi All,
I'm back from my family holiday, alas it rained everyday!!
Today I'll be steadily working through my backlog of emails and then
begin the task of tackling submissions.

Hi Bart,
You'll simply need to go through you scene graph and remove the
osg::LightSource nodes and an places where GL_LIGHT0... etc. are
enabled.

Hi Preet,
The OSG provides more than just support for passing data to OpenGL, it
does culling and this requires knowledge of the bounding volume of the
object. I would recommend sticking with using the standard
osg::Geometry::setVertexArray(..) for passing in the vertex positions
of your data so

Hi Martin,
There really isn't enough information about what you are doing to know
what might be amiss, it's just far too open ended.
The best thing you can do is use a debugger to track down what might
be going on in your application.

Hi Sevket,
For large paged database you'll need to use vpbmaster to create a set
of tasks that sub-divide down the database generation so that each
individual run of osgdem task will be small enough to avoid memory
issues. vpbmaster will allow you to use multiple CPU's on one machine
and a

If the fix works just post it to osg-submissions as a complete file
and I can review it.
Thanks,

HI Preet,
You'll need to rest OpenGL into consistent state when moving between
Qt and the OSG. I don't know anything about QGLFrameBufferObject so
can't comment on what state it'll be managing.
What I can say is that the OSG has it's own native FBO support that
will work just fine all by itself
HI Michael,
There a range of reasons why the OSG uses static for different places,
it won't be possible to remove these without breaking lots of
functionality, OSG API's and end user application usage. So it's far
from trival task with a dubious end value ended.

Hi Tolga,
The OSG selects LOD children dynamically within the cull traversal,
each independent traversal with have an independent result. This
means one shouldn't expect problems with viewing the same scene graph
from different camera views.
Is there a chance that more is going on? Are they
Hi Christian,
I have just checked the Viewer::updateTraversal() and associated
UpdateVisitor::handle_callbacks() code and it looks to me like a
StateSet with callbacks attached to a Viewer camera should have it's
callbacks called. I haven't tested the code though, too many other
tasks to get
HI Maia,
A osg::Switch node would be appropriate for toggling between
subgraphs, while an update callback would be appropriate for the time
based changes in state, and an event callback would be appropriate for
handling the events.

Hi Christian,
I have rather too many support emails to get through to look at
compiling and testing end user applications so I'll have to defer to
others to look at your app.
One thing I can add right away is that the osgUtil::Tessellator will
be just using vertex and primitive data when doing
Thank you for your input.
I now understand that the tesselation does not take into account any
vertex attributes, so I cannot really rely on the tesselator to
produce a visually pleasing result when these vertex attributes differ
from vertex to vertex.
I worked around it by manually specifying

This problem is still present.

OpenThreads doesn't expose thread local storage but does use it

Might it be possible to use this in your implementation?

the next source Texture will contribute to.

Sorry for the very long delay in getting to review your suggested

amendment I made to rename the parameter name Camera* pCamera to

Hi Riccardo,
On review of the submission I've decided that passing in a Camera

should be passed in rather than a pointer which could be NULL or
pointing to a valid Camera object. This brings the method more into
line with how
I used Collada dom 2.4. But in OSG WiKi:

With COLLADA DOM version 2.2. it works fine.
