Re: [osg-users] Native osgdb_bin format in progress (was: Develop a scalable binary file format for native OSG scenes)
Hi Robert, 2009/12/19 Robert Osfield robert.osfi...@gmail.com: Hi Wang, Wow, that was a quick turn around. I've begun a code review, and so far am impressed as how much code you've been able to share between the binary + ascii implementations. I do wonder about the performance impact on binary reading that there will be due to adding all the if statements that are required for ascii support. Have you performacne profiled the new plugin against your previous one or the .ive plugin? I didn't have a performacne test but I guess there will surely be efficiency loss while loading binary files with the existing bin plugin. In reviewing the wrappers I do wonder if we might be able to wrap the individual properties as objects in their own right, with each of these mini classes handling the reading and writing of that specific property, then the classes wrappers just containers for this property wrapper classes. I experimented with such an approach in VirtualPlanetBuilder's src/vpb/BuildOptionsIO.cpp. This approach extends the standard .osg format in a very compact way that is far less error prone and verbose that usual DotOsgWrappers. This approach does use lots of templates and macros though. To get a taste have a look at how I wrapped the BuildOptions class that has dozens of separate properties of different types: I'm going to look into the VPB source code these days. In fact I haven't explored this project before, although I'm using it every day. :) The above provides all the read and write support, with the properties being access via Type CLASS::getPROPERTYNAME() and void CLASS::setPROPERTYNAME(Type) methods, with macro's adding the get's/set's and types automatically. The VPB code doesn't support binary and ascii, and I haven't profiled how expensive it is in memory or speed, for ascii support I would expect it be pretty competitive to the standard OSG ascii, but for binary I guess it would fare less well w.r.t .ive. I think it will always be inefficient for a binary format if we parse property names and values in runtime, because of these excess parsing functions. Maybe we could just use templates and macros to implement ascii/binary support in the compile time instead. I will read the VPB source code through first and try to make some thoughs if possible.

Re: [osg-users] How to get average frame rate after some amount of running time?
Hi Dat, On Sun, Dec 20, 2009 at 8:26 PM, Nguyen Tien Dat tienda...@gmail.com wrote: Dear all, Could you tell me a way to get the average frame rate after, for example, 1 minute of running? The OSG itself doesn't give you this but it gives you all the tools to do it. You have an osg::Timer for the time, and your have control over the frame loop so you can count the frames - so you can just do it yourselves for all th timings. There is even an FrameStam viewer.getFrameStamp() that gives you the ReferenceTime and FrameNumber, see include/osg/FrameStamp for further details, if you just want to use the OSG built in timing/frame counting.

Re: [osg-users] Problem with using static initializers to preload plugins
Hi Paul, On Wed, Dec 16, 2009 at 6:57 PM, Paul Martz pma...@skew-matrix.com wrote: As you know, I have a private nodekit that uses the .osgb extension. In order to avoid collisions with the upcoming new OSG binary format, I've added a static initializer to the nodekit to force load my .osgb plugin. As we've discussed previously, this is what I need to do to avoid forcing client apps to do this explicitly, right? You don't need a static initializer, just preload in the main would be fine. Might I suggest not using an extension that is the same as .osg* extension as this would avoid the issue. I realize this will require a small amount of code + doc changes but it's only likely to be a couple of lines in both cases, and for modes that are already created you could use osgconv -e osgb option to convert them. My nodekit depends on osgWorks, which contains a plugin that supports the .skel extension. So, just to be safe and avoid possible future collisions with the .skel extension, I also added a static initializer to osgWorks to force loading the .skel plugin. The net effect is that whenever my .osgb plugin gets loaded, my osgWorks .skel plugin also gets loaded. This is correct and expected behavior. Just how likely is a extension collision though... if you are careful about it collisions don't happen too often, and rarely for one particular sector, so one typically won't hit upon this issue. The .osgb case is very much the exception. Unfortunately, this breaks osgconv --format osgb. Issuing that command incorrectly displays output for both my .osgb and .skel plugins. It should display only output for the .osgb plugin. The root cause appears to be flawed login in osgDB::queryPlugin(). This function is passed a plugin filename, which it loads, and then assumes that any plugins that got loaded must be appropriate to query. This is a false assumption in the presence of static initializers, as I describe above. Plugins can legally have multiple reader writers in them, and the whole readerwriter design is to be as decoupled as possible - this allows you to stick ReaderWriters in the main application, in a plugin that is dynamically loaded, or statically initialized... lots of different combinations. The queryPlugin() method has come a long time after the basics of osgDB and the plugins were put in place, and is designed to be a helper function that works well enough to get useful info out. If it doesn't always pick out the right information with unusually plugin combinations then this is unfortunate. The queryPlugin is not critical functionality though, it's something that osgconv uses for a bit of extra info, for normal OSG usage it'll be used very rarely. My personal preference would be to enhance Registry to handle multiple plugins that support multiple formats with the same extension, thus avoiding the need to preload plugins, as I have mentioned in other posts. But if this is still off the table, Having multiple plugins per extension supported in osgDB::Registry will complicate and already complicated set of codes. It's already hard enough to maintain and understand as it is, adding extra complexity would really have to be justified by something that effects all users, and in way that doesn't have any other solutions. In the case of multiple plugins per extension I just do see this strong need, we've gone a decade without absolutely needing it, the OSG has many thousands of users and they haven't been stumbling over this issue. There is also a solution - preloading for those who have the niche need of having multiple plugins per extension. Pre loading is one one line of code in an application - it's not complicated, hard to implement or maintain. Does removing this one line of code from an application of a small number of users justification for adding complexity into osgDB? For me it's a no brainer for me, the OSG is already complicated enough as it is, and there always the pressure from the community to add extra functionality and complexity, so keep to things manageable my role these days is largely about spotting ways to simplify or avoid further complication of the code base but retain the flexibility and functionality of it. then my fallback solution would be to change pluginQuery so that it takes an extension as a parameter, and only queries a loaded plugin if it accepts the extension. I guess one could add an extra extension parameter with a default of which would leave the behavior as it is now, and then when it's defined then use it to query the plugins loaded would work. Do either of these sound acceptable? If so, let me know which one and I'll code it up. The changes to pluginQuery seem like the more sensible and least intrusive approach. Yes it'll add complexity, but it's encapsulated within a single function so the opportunity for regressions and difficulties in maintenance are much less of a concern. Robert.

Hi,
I am not a QT expert but has done this in the past with MFC. You simply
create nodevisitior that will traverse the scene and create your tree items

Re: [osg-users] Creating tree model of scenegraph for use in QTreeView
If the tree control you're referring to is like most 2D UI tree controls, then each node can have only one parent. This is not the case in OSG, nodes can have multiple parents. So you'll need to figure out a way to represent this.

Re: [osg-users] Get Vertexdata from osg File
Hi try lesson18 from,
the tutorial examples form Leandro Motta Baros. The whole tutorial series is on
the site on the Tutorials section.
http://www.openscenegraph.org/projects/osg/attachment/wiki/Support/Tutorials/LMBs_OSG_Examples.zip
In short he uses the TriangleFunctor class to let osg give you the triangles it
produces when it is actually rendering.

Re: [osg-users] Transforming nodes
bump... I've managed to insert DOFTransform nodes into my model but the geometry under these nodes are not being drawn even though the drawable update callbacks are definitely being called... The weird thing is, if I replace the DOFTransform with a simple MatrixTransform, the geometry renders just fine. :? If I just leave the put and inverse put matrices as identity matrices, it should still render, right? what am I doing wrong?? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=21732#21732 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] OpenGL B-spline support?
I don't believe there is support for OpenGL evaluators in OSG, but you could easily do a recursive grep on the source to see for yourself. OpenGL evaluators have been removed from the OpenGL spec as of v3.1. The modern way to do this would be with a geometry shader.

Re: [osg-users] QOSGWidget display problem
Cedric, Martin, et al. I'm glad the null-returning QPaintEngine function seems to work for you. Unfortunately, I don't really have any other suggestions for testing it to determine whether or not you should label the fix acceptable. This is a question each project team must answer for themselves. I might recommend answering at least the following questions to make the determination (among any other questions that your project may need to be answered). 1) Is the behavior acceptable? 2) Does this solution fit well in the context of the documentation and the public interface for each library that is involved? 3) (Project team member responsibility) Is the solution documented so that other developers on the team can understand the purpose of the solution, its prerequisites (if any) and its side effects (if any)?

Re: [osg-users] help with osgCluster...
Shayne, Right, you use the same scenegraph on all machines. The following should work on the master: osgcluster -m cow.osg and on the slave: osgcluster -s cow.osg I just tested this and if you want to viewports to match, you'll need to tweak the fov and offset parameters. With the above command line, the slave will just show a portion of the view. If you zoom in from the master window, the cow will eventually come into view on the slave.

Martins, Ok, I got what you suggested working...on the same machine. Now, what if I want to do the same thing but instead have the master on one machine and the slave on another different machine. In order to do this, don't I need to specify the IP addr of the broadcaster somewhere? I notice that broadcaster.cpp has a setHost method but it's not being used in osgCluster.cpp. I tried issuing the commands below with the master on one machine and the slave on the other and it doesn't work.

You can grasp the understanding and make yourself in GLSL. I can't find the real worldz examples on the net, do you have the source? Grab the GLSL book and look at Real Worldz section. There is not comprehensive source code and example, there is only information to how you can create water surface.
