Hi Mathias,

Hi Tran ,
Please note that you must change the state of an object in a protected (
i.e. update ) portion of your OSG code .
Maybe MFC has nothing to do with your problem.

i'm working on model-paging in flightgear. it works fine so far, but i had to
introduce some quirks to get around the limited hooks in PagedLOD and

You could you explain the motivation behind these changes, i.e. what
problem do they solve that is currently limiting your work? It may
well be another solution to the problems you are solving, or it may be
that are refactor elsewhere or in a differnt form is more appropriate,

hi robert,
in flightgear we have xml-files that describe models. the code that reads
these files needs options passed in:

Hi folks,
just some thoughts about texture attributes (or all
other attributes in general):
If we first setup a texture attribute on a StateSet,
lets say for the texture unit 0.
After some time we remove this attribute and assign it
to texture unit 1.
This would end up in the texture bounded
HI Art,
OpenGL doesn't have a concept of unbinding attributes, and neither
does the OSG. OpenGL has the concept of enabling and disabling via
mode, and the OSG maps this via StateSet::setMode(..) and
setTexureMode(uint unit,...); My guess is that you are looking for :
Hi All,
I think I can now shed some more light on this problem, and perhaps I have
found a potential bug.
In the last update to this issue I had tracked the problem down to something to
do with osgSim not wanting to load as a dependency of osgDB_ive.dll - and
osgDB_flt.dll. On further

yes this is one of the solutions, however I am
wondering why this is not done automagically by the

Hi Neil,
Which version of the OSG are you working with? I have just checked
the SVN version of the CmakeLists.txt for ive and OpenFlight plugins
and both correctly list osgSim as part of the list of dependencies.
Unless the build system isn't working this should ensure that the libs
are linked

Because removeAttribute removes an attribute not any modes.

as tim moore told me (off-list), we already have a subclass of DatabasePager

I think you're correct. I think this is an issue within MS and ActiveX

dependencies of libraries that are being loaded, when issued from within an
