Re: [osg-users] Solving forum.openscenegraph.org problems
And for a long term solution, what about moving everything to Google Groups ? It can be used as a mailing list or as a sort of forum depending on the user preferences. On Wed, Jul 31, 2013 at 5:05 AM, Wang Rui wangra...@gmail.com wrote: Hi Robert, I'm currently working on the Chinese translation of OpenGL Programming Guide 8th Edition, as well as some client projects. It's heavy work for me so sorry for not being with the community these days. Fortunately I'm going to have a few more time later and will be back for more tests and feature addtions :-) In 2008, I started a Chinese OSG forum (bbs.osgchina.org), and have been managing it until now, which has about 7 housand members and more than 50 thousand posts. My experience is simply that you can hardly satisfy everyone who has questions in the forum. In most cases, askers will only put the questions like 'why my scene is black' or 'how to implement 3DGIS software', and it is nearly impossible to give a complete answer. I will always ignore such topics or just give an one-line answer to save their time and my time at that time. :-) We had better support forums and even social networks for OSG users, especially those young men, to get in touch with each other. This will also help OSG itself to grow more quickly and get more attentions when related news are coming. Release news will also receive more feedbacks if published on forum. In fact, in my opinion, the forum should not be somewhere filled with questions and answers, but a place for sharing ideas and achievements, making friends, and looking for opportunities. We need not only moderators but also active members to publish news, feature suggestions, discussions and project galleries in the forum, to attract more people to attend and encourage them to share their ideas, too. Wang Rui 2013/7/31 Björn Blissing bjorn.bliss...@vti.se Hi Robert et al, I would love for the forum to keep working. The forum is usually my goto place to find new information about OpenSceneGraph and I actually like the format better then the e-mail lists. Although the current state of the forum makes me a bit sad for the new users. I have been contemplating volunteering to do some basic moderation, ie. proof reading the first messages that users post before getting forum approval. My main hesitation has been, as I guess for all of you, lack of time. I also tend to work with OSG related project in irregular time periods. I have actually been working with OSG on and off since 2002. (My first experience with OSG was at a presentation that Robert held in Stockholm in November 2001). I usually work with it for a month or two and then I am away from the community for a couple of months doing other projects. The forum is perfect for this on-and-off lifestyle since it doesn't clog up my e-mail folders when I am inactive as a OSG user. (Registering and unregistering from the email lists became rather tedious.) So rather then letting the forum die, I would like to volunteer as moderator. Although I probably would be a moderator that would be rather inactive during some periods. But if there are more moderators our inactive periods hopefully shouldn't overlap too much. TLDR; I hereby volunteer as a forum moderator.

Re: [osg-users] Solving forum.openscenegraph.org problems
Yes the main benefit would be to bring everybody at the same place. I think that currently the problem is that newcomers are using the forums, but most active users are still using the mailing list, and moderators should be easier to find from active users than newcomers. In my case for example, I'm OK to do some minor moderation work, but I never volunteered for the forums as it's something I'm not using and I'm not willing to. Apart from that it seems than migrating from mailman to Google Groups seems to be quite common, and by googling a bit you can find how to import all the contacts easily.

On the mailing list side I typically only need to handle a couple of moderation items per month handling cases when users post attachments that exceed the amount listed, it's not much but effectively other moderators could help with this, I could help with moderation on the other side when need be - the advantage is pooling manpower.

Re: [osg-users] OSG plugin for browsers
Hi, Did you looked at Google Native Client : http://code.google.com/chrome/nativeclient/ Cheers, On Thu, Apr 7, 2011 at 11:30 AM, Thibault Genessay tibog...@gmail.comwrote: Hi folks, I have been looking for quite a long time for a way to integrate OpenSceneGraph applications in web browsers. Several plugins seem to have emerged in the past years: - osg4web (project created on Google code, nothing to download) - gvsig3d ( http://gvsig3d.blogspot.com/2010/02/openscenegraph-plugin-for-firefox.html ). Very promising, but I can't find any source code, if any is to be published some day. - The so-called OSG Viewer Firefox Plugin 1.0. I can't find where this one originates from, so I didn't install it Other people have thought of alternatives to display 3D content: - osgjs - which re-implements the OSG in Javascript. Although the API is very close to the C++ one, it is not a way to embed an OSG app in a browser - webGL. If I am not mistaken, this leaves out the OSG entirely, and only aims at displaying 3D models. Kind of a new VRML thing. I recently stumbled upon FireBreath (www.firebreath.org, licenses: BSD or GPL). This very smart software (at least, according to the videos on the website) let you build plugins that are compatible with all major browsers by relying on either ActiveX (for IE) or the NPAPI (other browsers). BUT: it only works on Windows platforms. I have also tried to develop my own plugins for Firefox and Safari. Both are so huge and so complicated (e.g. lack of accurate documentation of Firefox) that I never managed to build something convincing. Plus you have to focus on each browser's specifics instead of focusing on the OSG/Javascript interaction. At this point, and because I somehow need to have users being able to view OSG content on the web in a robust and predictable manner, I am leaning towards FireBreath. Not having to care about the browsers' internals is such a huge benefit that I can accept its Windows-only nature. However, if any people on this list have experience on developing cross-browser, cross-platform plugins, I'd welcome all input, suggestions, trout slaps for being such an MS-ass. It is quite evident that the ideal plugin would be: - available for all platforms (even smartphones) - for all browsers - in all languages (UI language: e.g. English, French) - in-line with the current OSG development - fully open-source, of course - built just like a native OSG executable I am very willingful to share my work on this plugin, but I feel like going alone is not a good option. My needs are quite basic, but my experience with browser plugins is small and I certainly miss out important features. Plus the task of making it right takes certainly more than a decision of a single person. I think the long-term success of a browser plugin needs some planification.

Hi,
Thanks for your replies, it confirms what I was thinking... The iOS way of
sending events seems to be an exception, all the touch technologies I use
(mostly MPX, Windows 7 and TUIO) send them separately, so I think it should
be useful to add to EventQueue a way to track the events to put them
altogether into the GUIEventAdapter, what do you think ?

You'll have to store your touch-points and submit them alltogether as
one event to the eventqueue, here's some pseudo-code:
osg::ref_ptrosgGA::GUIEventAdapter osg_event(NULL);
for(int i = 0; i numTouches; i++)
{
// get touch i and corrsponding phase, x and y
...
// feed it to the osg_event
if (!osg_event) {
osg_event = _win-getEventQueue()-touchBegan(i, phase, x, y);
} else {
osg_event-addTouchPoint(i, phase, x, y);
}
}
As Paul noticed in one of his recent mails, the design of the current
implementation is not the easiest and cleanest, but I was happy to have
something working on my end. So if you have any improvements to the
design/code, please share them with us, so we get a robust and clean
multi-touch implementation working consistent on different platforms.

Re: [osg-users] Viewer-frame() Qt - embedding osg scene into Qt app
Hi John, What you're trying to do is really nice, any chance you'll share the code ? It could make a cool OSG and QT example. Cheers, On Thu, Oct 28, 2010 at 10:16 AM, Robert Osfield robert.osfi...@gmail.comwrote: Hi John, My guess is that the OSG is setting some OpenGL state that is being inherited into the Qt GL drawing code. Mixing OSG and other GL code is a little tricky as the OSG uses lazy state updating to provide efficient use of OpenGL/graphics card, this lazy state updating means that the OSG assumes the state is the same going into it a new frame as it was when it left it. The OSG also can modify the current OpenGL state and leave it in that state, as it has the knowledge of what the state is so can get it back to the state it needs on the next frame. The osg::State object associate with each GraphicsContext is what the OSG uses to track and apply the state. The use of lazy state updating means that you need to avoid other OpenGL code changing the GL state without the osg::State knowing about it. The two ways to achieve this is to use glPushAttrib/glPopAttrib around the non OSG GL code, or to use the osg::State::haveApplied*() methods to tell the OSG that the non OSG GL code has modified a particular part of OpenGL state. The other issue, and the particular one you are most obviously facing is that the OSG is modifying the state and the non OSG GL code doesn't know about this so doesn't reset it. Two approaches you could take would be to use the glPushAttrib/glPopAtttrib around the OSG calls, or use a StateSet at the top of the scene graph - or the master camera's StateSet, to set the state into a known state, and make sure that this is applied to the osg::State right after the viewer.frame() call.

Re: [osg-users] OSG seems to have a problem scaling to multiple windows on multiple graphics cards
as fast as a single process. All four cores are at near 100% CPU utilization according to top. So far, so good. Now we modify the program to load the model and create multiple windows on multiple cards. There's one window per card and each uses a different core. (3) The threading model is CullThreadPerCameraDrawThreadPerContext, the default chosen by OSG. The environment variable OSG_SERIALIZE_DRAW_DISPATCH is not set, so it defaults to ON, which we think means draw in serial. If we draw to four windows on four different cards we get about 36 FPS. There are four different cores being used, and each has about 25% of the CPU. This probably this makes sense as the draws are in serial. 150 FPS/4 is about 36 FPS. As expected, we get nearly identical results if we create four windows on a single card using four different cores. If we set OSG_SERIALIZE_DRAW_DISPATCH=OFF we hope to see better performance, but with four windows on four graphics cards we only get 16 FPS! There are four different cores bring used, one at about 82%, and the other three at 75%, but what are they doing? Again, we get nearly identical results if using four windows on a single card. So How can we get OSG to draw to four windows on four cards in one process as fast as running four separate processes? Any pointers or suggestions are welcome. Thanks, John 1 - Our immersive system consists of 3 projectors and a console each driven by an Nvidia FX5800 graphics card all genlocked for 3D stereo display. The four graphics cards are in two QuardoPlex Model D2 units connected to the host. The host computer is an 8 core Dell Precision T5400 running 64 bit Linux (CentOS 5.5). We are using Nvidia driver version 195.36.24 2 - the program is attached- it uses only OSG.

I've made some updates to the site with new screenshots and small descriptions, and I wanted to try and solicit some more feedback since it's been a while since I've mentioned them here: http://osgpango.googlecode.com A lot has changed with osgPango (far more mature and flexible API, no more fixed-function support, up to 8 combinable textures per font, multi-pass rendering) and I'd be interested to see what people think. In the very near future I will be providing the equivalent of the famous 3rd Party archive for osgPango for Windows. In Linux, it is quite trivial to compile both osgCairo and osgPango. In Windows, until I can create the necessary dependency libs, it's best to use the GTK Win32 Developers Bundle: http://www.gtk.org/download-windows.html In fact, my current client is using osgPango exclusively in Windows, so don't be too intimidated by the mention of GTK or anything like that! The current Text object (a derived class from osg::MatrixTransform) isn't a drop-in replacement for osgText::Text, but learning how to use it properly isn't hard. Plus, if you can position a MatrixTransform in your scene, you can position osgPango::Text geometry in your scene. :) Or you can create your own Text class and manipulate the Geometry however you want... I've also made some pretty significant changes to osgCairo that I'd like Robert to take a look at. :) A while back he had some interest in Cairo and didn't really like the idea of creating and maintaining our own C++ wrappers. Well, I've come around to that same manner of thinking, so osgCairo is really little more than a stripped down wrapper over osg::Image, a fancy ReadFile implementation, and a few commonly-used utility functions. It's a tad more sophisticated than what is already in OSG, but not by much.

Re: [osg-users] osgPPU osgShadow
Hi Martin, thanks for your reply but I am talking about another problem. The problem with osgShadow + Seven/Vista + fullscreen = black screen is pretty familiar to me, but I always disable aero on final setups so it's not a deal. My current problem is with osgShadow::MinimalShadowMap and osgPPU, my scene becomes white, but it works with the osgShadow::ShadowMap technique.

I did, however, enable vync via the old env var: export __GL_SYNC_TO_VBLANK=1 There is slim chance that this might work... you never know with closed driver what the logic is. Another thing you might try is to create two graphics context, one for each card and then use twinview to have a single context across both screens. On the OSG side you can create two contexts and just have two cameras per context, using different viewports to select the appropriate part of the view. You may even be able to just use a single camera across both screens if your displays are abutted vertical/horizontal in the form of a powerwall. If you can use a single graphics context per card then you'll get better performance, and if you can use a single camera per card then you'll get the best performance out the system. Whether twinview will solve the vblank issue I can't say. There is chance that NVidia reserve this for the Quadro's that have support for genlock and swap ready. Robert.

But if I let the first video playing some time (about 10 or 20 minutes), when I try to browse my images, sometimes I get white squares instead of them and this error : OpenGL error : out of memory This error only happens if I let the first video playing a moment.

Thanks for your advices Robert, anyone had some success on configuring and sharing graphic contexts on Windows 7 ? We'll also try the 4 images based on one big image and let you know how it goes.

Maybe the problems comes from having one texture shared on 4 contexts and only one card, on the final setup we'll have 2 graphic cards. Do you need 4 contexts? If you have one card I would typically try to run it with a single context across all outputs. With two graphics cards you wouldn't be able to do this, but still I'd opt for two graphics contexts, one per card. This does assume that your OS of choice actually supports driving the graphics cards efficiently... Perhaps one solution you could go for is to have four textures that each have their own osg::Image, but each osg::Image points to a different point in the larger osg::Image. If you place render the video as four images down, one wide, rather than four wide and one down then you'd be able to use a simple pointer offset into the osg::Image that ffmpeg is writing to. Using this approach you could avoid major cache misses, and avoid the need for sharing a single big texture.

Re: [osg-users] Improving the OpenSceneGraph project efficiency and balance
Hi all, Currently in our company workflow we use SVN to manage our projects, and we're plugged to OSG head as a SVN external, it's very useful for us to get updates from OSG in live. If OSG migrates to something else like Git, is there any way to still have an automatic SVN mirror ? We'll not move all our source management to something else than SVN, and multiplying tools to get the sources will be painful. Thanks !

Right now I do a From FirstName SecondName, details in all submissions, then use osgversions -R ChangeLog to parse out the authors, and make any typo corrections made to FirstName SecondName that might have been made, as well as pick out authors names from a time when I hadn't yet adopted the From scheme. It kinda works but it's hacky. It'd be good to have the authors names formally assigned to submissions, this is all made a bit more awkward but the fact that a maintainer who's not the original author will be doing the formal commit to the main repo. Actually knowing who the original author and the maintainer who did the review and merge is useful. Is this possible? When importing the subversion history it'd be good to sort out the old submissions to have the authors assigned from formally (ideally typo's fixed :-). I don't doubt this is a job that could be partly automated, but will still require quite a bit of human review and editoring. The hacks in osgversion to compenstate for the typo's might be help here.

I'm under Windows 7 and VS9 Express, is anyone experiencing this kind of problem, or is having success playing multiple videos with sound ? I would also like to know if anyone knows how to control the sound volume with the SDL ?

[osg-users] Native multitouch support on OSG
Hi Robert, Just a quick question, are you inclined to see native multi-touch support for OSG ? We should only need to add an ID information on the GUIEventAdapter class to be able to make the difference between 2 or more push from different points. It will be enough to handle basic multi-touch support (the next step should be to add pressure information like the size of a point). Then it will be possible to modify the GraphicsWindow* files to add this information on the events for systems working with multi-touch (like Windows 7, the latest OSX, Linux or IPhone).

[osg-users] How to get events from interactive images
Hi Robert and all, I have a question about plugins and how to handle a specific case. Let's say that I have a plugin which returns an interactive image (like the pdf or browser one), I associate the image to an interactive image handler to send it events. Up to here, everything works as expected, but now, I need my interactive image to send me information about the navigation. For example with the browser plugin, let's say I would like my interactive image to tell me when the user clicks on a link to be able to filter the websites where the user browses. How can I handle this case without including some code from the plugin ? In a more generic way, do you think it can be possible to have a generic path for the interactive images to send back events to the application ? The InteractiveImageHandler should be the place to put such a mechanism ? Thanks in advance for any help on this subject !

On Tue, Dec 1, 2009 at 4:56 PM, Robert Osfield robert.osfi...@gmail.comwrote: Hi Serge, The basic event handling support in osg::Image is to enable browser style interactivity but is limited to only putting events into the osg::Image subclass - there is no support for getting events out. There is a limit to the type of events you could get out too - as osg::Image doesn't know anything about the potential sublcasses from osg::Image. The InteractiveImageHandler is also in a similar position - it knows nothing about the osg::Image subclasses - just enough about osg::Image to pass events into it. To get events for the browser subclass from osg::Image one will need to know about that specific subclass i..e osgWidget::BrowserImage. This as yet isn't geared up for passing any events back or providing a callback mechanism for it, but this is for sure the place to put them. This way you could do a dynamic cast to BrowserImage and then add the extra handling your need. To do this we'll need to extend BrowserImage but this would be perfectly in keeping, BrowserImage itself is still in it's infancy, a first pass at what will be required for more fully featured browsing.

I'd be very interested in your opinion on this as well, Robert. I often
find myself wishing that Image objects had an update() method as well,
but I don't know if I'm misusing OSG or it makes the most sense for you
to put logic in the parent Geode instead, like Sergey is doing.
The update method already exists (Image file line 327) :
virtual void update(NodeVisitor* /*nv*/) {}
But I think there is no visitors to call it (but I've probably missed
something too).

Re: [osg-users] Multi-touch in the OSGViewer and camera manipulators
Hi, We also have some multi-touch devices here (a FTIR projection table and a PQLabs screen). We've made it works with OSG by adding some custom data to the classic events. For example for a mouse push, we add the mouse ID as an user data. Our FTIR table use the TUIO protocol and we've made an OSG event handler based on it, it works without problems. As the democratization of such devices is on the way, it should be interesting to add this kind of data (touch ID, touch size...) directly into the OSG event structure to be able to make MatrixManipulators or EventHandlers taking advantage of it directly into the Core OSG. Another solution for you is using for example PQLabs embedded feature to bind a multi-touch gesture (like rotating) to a key from the keyboard. With this solution you can easily simulate a multi-touch behavior, but it will not be very precise.

Most multitouch solutions use back-projection and capturing the field of input with a infrared-camera with the help of infrared-laser, -leds. and how difficult would it be to add Multitouch capabilities to OSG? In particular I was wondering what it would take to support Multi-Touch capabilities in the various Camera manipulators - and how to get the special input events from various operating systems (Mac, Windows, Linux). There's an opensoruce protocol called tuio which sends a stream of events via UDP to a host. So you can change tracking solutions without changing your source. In particular zooming with two fingers would be extremely cool (the pinch gesture) , and grabbing an object with two fingers, rotating it (or the camera around it) in the 3D view according to how the two fingers move.

Even with a dirty method (reseting it's tex coords on the drawable or something like that). Wojtek is right (of course, having implemented some of the ShadowMap techniques in OSG, he would know), ReceivesShadowTraversalMask is typically not used in ShadowMap techniques, as it would be a bit hard to implement generally. What we do is we have a uniform ShadowEnabled which if disabled skips the shadow map lookup in the shadow map shader. For this to work you have to replace your shadow technique's shader with one that will use whatever uniform you set, and you need to set a uniform to false (and make it default to true in your root ShadowedScene) instead of using the ReceivesShadowTraversalMask. So it's a bit inconvenient, you have two different ways of doing things - CastsShadowTraversal mask to make something not cast shadows, and a uniform to make it not receive shadows. Though it's kind of appropriate if you think about it, the former is do I use this object for shadows, and the latter is do I use the shadows on this object, so intuitively the former is a node mask and the latter is a shader parameter for the output.

[osg-users] osgShadow question
Hi all, I am currently using osgShadow with the MinimalShadowMap technique. It works great but I have a question : - In my ShadowedScene, I set the children's nodemasks accordingly with the CastsShadowTraversalMask and ReceivesShadowTraversalMask properties, but it seems to not work, everything cast shadows on everything. Anyone knows if there is a way to force an object to not receive the shadows ? Even with a dirty method (reseting it's tex coords on the drawable or something like that). Thanks !

Re: [osg-users] FFmpeg questions
Hi all, I've made a test with the osgmovie example and I have the same behaviour. Using the ffmpeg plugin (by adding .ffmpeg to my file path), when it starts, everything is OK, my movie is played. But if I pause the movie, then wait 5 seconds and play it again (with the key 'p'), the movie is played too fast during 5 seconds... Anyone can test the osgmovie example on its OS/configuration (with ffmpeg of course) and tell me if you have the same behaviour ? Maybe it's a problem with my version of FFmpeg, or a problem with Windows... I can even send you my movie if you want (send the request by mail), it's a .flv one, but I have also made tests with avi files and I have the same problem. Thanks !
