Hi Tom, On 12 April 2012 01:16, Thomas Hogarth thomas.hoga...@gmail.com wrote: So I've been playing a bit more with mediawiki, seems pretty good. http://wiki.openscenegraph.com/index.php?title=File:Stereomagic-screenshot01.png Not much but adding the links and image was very easy. I've also been having a look at features that could make the tutorials easier to follow. Found this plugin for syntax highlighting. http://www.mediawiki.org/wiki/Extension:Syntax_Highlighting Thanks for doing the experimentation. Could you try and put together a test tutorial on any subject that you feel able, iOS for instance. Your experience with this will give us an idea of how they might look and how quickly/easily they can be put together. It might also be useful to attempt to copy the contents over as a straight joomla article to see how easily one can do the equivalent in joomla. So is the plan to flesh out what you have on Joomla site (downloads, about, screen shots, pr etc), then move everything in the documentation section of the current site over to mediawiki? This has been my initial plan of action. However, I am starting to wonder if the ability of Joomla to handle creation and editing of content within a browser is not so different to that of a wiki so it might be possible to do everything within Joomla rather than have a wiki and a main website. A wiki does have it's own advantages though so I'm torn. For the average end use they just want easy and quick access to information, downloads and support, whether it's in a wiki or not makes no difference. For those populating the website(s) it's a different set of needs. This initial experimentation stage is really about trying to flesh out what is possible and what might work well for us. I don't know the answers until we've done the leg work. I'd like to get a firm direction within the next week as we really need to start pulling across content and building the new website.

In my ideal world we'd have the forum, mailing list and websites all handle with the same logins. I'm guess this would require some kind of customisation of Joomla if we were able to do this.

Hi All, Those who haven't received their activation email I have used the joomla admin pages for the registered users to activate and enable the accounts for you. We still need to sort out the issue with the mails being eaten as spam, but at least this hurdle shouldn't stop you from joining in the experiment. The next step will be to identify what bits of the website are most critical for populate and they get these pages dealt with, either by me or by others who'll I grant access rights to. The question is what rights should we open to to whom. See below for the list of different groups that Joomla has be default. Public |— Manager |—|— Administrator |— Registered |—|— Author |—|—|— Editor |—|—|—|— Publisher |— Super Users Right now all those who've registered are listed Registered, except for me and I'm listed as Super User. I'm guessing that we'll have a small number of Administrator/Managers and then a wider set of Authors, Editor and Publishers. Those who've worked on Joomla websites will know a bit more about what types of rights are required so let us know your experiences and recommendations.

Re: [osg-users] Play audio files
Hello again,
I know that is has been long time since the last message about this topic,
but I am still facing the same issue. The audio is still delayed in the
videos.
But now I have found that if I change
ulBufferSize = (ulFrequency * bytesPerSample) 2;
by this
ulBufferSize = (ulFrequency * bytesPerSample) 4;
in the AudioSink.h file, the delay disappears in some videos. I don't
understand quite well why it disappears and why it is only in some videos.
The thing is that in one mpg video, the delay has completely disappeared,
while with one flv video the delay has not disappeared, but has been
reduced. If I convert that flv video to mpg, the delay remain the same, so I
actually don't know if the problem is with the video format, the AduioSink
buffer, or if it is about the libraries (osgAudio, openAL, ffmpeg...).
I have tested with openAL soft and with openAL and I am getting the same
behaviour with both.
Anybody has any idea about this problem? Maybe the buffer change can give
the clue to solve it.
Thank you in advance.

Thank you Chris for your reply.
I am still trying to solve the problems. One thing that have helped me is
changing this line:
AudioSink(osg::AudioStream* audioStream): _started(false), _paused(false),
_audioStream(audioStream) {play();}
for this line:
AudioSink(osg::AudioStream* audioStream): _started(false), _paused(false),
_audioStream(audioStream) {}
I don't know if there is a logical reason for that, but when deleting the
play(), the cutting in the audio seems to disappear. OK, it still makes some
cuts, but they are very small and it is possible to hear the audio without
problems (with the previous cuts it was impossible to hear the audio).
But I am still facing the problem of the delay. The audio starts delayed for
some reason that I can't still figure out. Could it be because I am using
openAL soft instead of openAL? Maybe that's not the problem, because it is
working fine with audio files, but who knows...

[osg-users] Warning: Manipulator warning: eventTimeDelta = -0.004
Hi,
When I use the FlightManipulator, I have a lot of warning messages:
"Manipulator warning: eventTimeDelta = -0.004".
The messages are displayed only using ON_DEMAND rendering.
The GraphicsWindow has an event queue. The window related event
(mouse move, ...) are appended in this queue.
The osgViewer::View has also an event queue (not shared with the
window). A FRAME event is pushed in this queue in the advance
method.
A frame is made of:
advance
{
push FRAME event time = reference time = delta_s(view start
tick, now)
}
eventTraversal
{
gw-checkEvents = fill the GraphicsWindow event queue
time = delta_s(event queue start tick, now) FRAME event time
append gw events to a local event queue
append view events to the local event queue
here, the local event queue contains:
gw event (time = T)
gw event (time = T+1)
gw event (time = T+2)
...
FRAME event (time = T-1)
the local event queue is not sorted (by event time) and the
FlightManipulator doesn't like it.
}
The warnings are not printed in the CONTINUOUS rendering mode
because the takeEvents method (used to takes the events from the
graphics window event queue and the view event queue) uses a cutoff
time (reference time). The window events are processed by the
manipulator during the frame N+1.
These messages are quite annoying. They exist in OSG 2.x but they
are notified as info (most of the time not printed).
I don't know how to correct this issue:
sort the local event queue (using the event times) before the
event dispatch
always set cutoff time = reference time
make the manipulators more flexible
...
Any ideas ?

Re: [osg-users] Building new website, assistance appreciated!
Hi Robert So I installed joomla on my server and have had a little play with it, seems easy enough to edit stuff Thanks for doing the experimentation. Could you try and put together a test tutorial on any subject that you feel able, iOS for instance. Your experience with this will give us an idea of how they might look and how quickly/easily they can be put together. It might also be useful to attempt to copy the contents over as a straight joomla article to see how easily one can do the equivalent in joomla. Sure I can do this, I think I will do it in Joomla if you could give me editor (or is it publisher) rights. I can start it on my server just for testing purposes. In terms of quick copying over I guess copying from the Trac editor (assuming it has one) will work best. Or trying to copy html into the joomla html editor. Just to make copying of URLs easier. So I will start with a Getting Started IOS document, and see what plugins joolma has to offer for Syntax highlighting etc. Cheers Tom -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=47021#47021 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

The question is what rights should we open to to whom. See below for the list of different groups that Joomla has be default.

I'm guessing that we'll have a small number of Administrator/Managers and then a wider set of Authors, Editor and Publishers. Those who've worked on Joomla websites will know a bit more about what types of rights are required so let us know your experiences and recommendations. Our sites have always been pretty small, so we've only ever had the Super User have the ability to do administration, create articles, etc. I know Joomla can handle it, but I've not seen how it works myself.

[osg-users] problem with handleMouseRelease using custom camera manipulator
Hi, I’m using OSG with Qt. I want to change the mouse cursor when I press and release a mouse button over my QGLWidget. I’ve created a custom camera manipulator by subclassing TrackballManipulator, and overriding handleMousePush() and handleMouseRelease(), in which I call QWidget::setCursor(). However, the cursor does not change immediately when I click or release the button. It only changes after the first mouse movement after the click or release. When I debugged my code I saw that handleMouseRelease() is not being called until the first movement after I release the mouse button. What do I need to do to be able to take action immediately when the button is pressed/released? I’ve set up the Qt widget similar to the osgViewerQt example. I am using OSG version 3.0.0 and Qt version 4.7.1. ... Thank you!

[osg-users] Quick questions about assigning render bins
I need to render a bunch of different objects using layer data and I'm doing it by disabling depth test and specifying a render bin to control render order... something like myObject-getOrCreateStateSet()-setMode(GL_DEPTH_TEST,osg::StateAttribute::OFF); myObject-getOrCreateStateSet()-setRenderBinDetails(11,RenderBin); * Should I be doing this on a per-object basis, or would I see better performance if I created group nodes with the right renderbin setup and then added the objects to the group nodes (assume hundreds of objects, but 10-20 layers)? (I don't know how OSG sorts/orders the scene graph nodes before rendering) * Some of my objects have transparency, but again, I'm specifying render order. So is it okay to put those objects in the RenderBin renderbin as opposed to the DepthSortedBin? If Objects A and B are both transparent, both in RenderBin (10) and RenderBin (11) respectively, and A is behind B, I should see object A through B correct? This is what some preliminary test code seems to indicate (and in that code switching from DepthSortedBin to RenderBin doesn't result in any changes).

[osg-users] osg_NormalMatrix calculated incorrectly
Hi, I believe osg_NormalMatrix may be being calculated incorrectly in the trunk version of OSG. At present, it is calculated as the inverse 3x3 of the modelview matrix, but should be the transpose inverse. The patch below appears to correct this. To test, try running osgsimplegl3 cow.osg. You will see the cow is mostly black until you spin it around a bit. After the patch is applied the cow appears fully lit all the time as expected.
