Hello,
First, I'd like to say Thank You to Robert, Simba, and Chris Denham for
helping me with my last problem with the DatabasePager. Chris's
suggestion worked great.
I just recently upgraded from OSG 2.4 to 2.6 because I needed
multisample support for my FrameBuffer Objects. When I did this,
everything worked fine execpt for two things which may be related. The
first was with osgEphemeris, and I found someone in an archive who was
able to fix that problem by making sure that the computed sky texture
was marked dirty() when changed. Robert said on the list that it "[had]
been relying upon an inefficiency in the osg::Texture2D::setImage()
method that has now been fixed, so only really worked previously by
fluke." This leads me to believe that maybe more efficiency changes were
made between OSG 2.4 and 2.6 which could be causing my next problem.
The second problem I have is that none of my Sequences seem to work
right. I tried a lot of things outside OSG to make it work, and
eventually did a diff on the OSG 2.4 version of osg/Sequence.cpp and the
OSG 2.6 version to find out that they are identical.
The problem goes like this. When I load a model with an Sequence in it,
the sequence runs one time. I cannot restart it ever. If I load the
model, then find the sequence node and stop it before it's drawn, I can
never start the sequence. This worked great in OSG 2.4.
So I built the osgsequence example in 2.4 and 2.6, and as I suspected,
the 2.4 version of osgsequence works great, but the 2.6 version does not.
I'm not sure what the problem is, since like I said, Sequence.cpp hasn't
changed at all. My suspicion is that, like the osgEphemeris problem
described above, something in 2.6 has been fixed so that it requires
notification of a change of state in the Sequence (something like a
dirty() being called?). Of course this is only suspicion, and I have not
been able to debug it very well. I'm hoping someone who knows the code
better than I do will be able to find the problem quickly.
So I guess that's it. I think that if the osgsequence example could be
made to work, that my sequence problems would be fixed.
Thanks for all your help, and again, thank you for Open Scene Graph,
Alan.
