Re: [osg-users] PositionAttitudeTransform question
Hi, I'm not sure to understand you problem... First of all, if you make a setScale(1,1,1) it is normal that nothing changes... After, your problem is not clear... you use a PAT for moving and scaling... and you scale the object separately ? Please be more precise... what does your scenegraph looks like ? Vincent. 2008/3/14, [EMAIL PROTECTED] [EMAIL PROTECTED]: I have a geode that I have added as a child to a osg::PositionAttitudeTransform. If I call setPosition (x,y,z), it seems to work OK. If I then call setScale with (1.,1.,1.) as arguments, it doesn't change as expected. But, if I change the scale values to something other than one, in addition to scaling the object, it also moves it. How do I separate the two so that setScale only scales after a translation, not move it to? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

I noticed it does leave large temporary files lying around after finishing the database: temporaryfile_imageFileName is left in the output directory. Should osgdem delete this after a successful run? This is not new behavior, and has been present since (at least) the last developer release. I am running the following command: osgdem --terrain -d elevFileName -t imageFileName -o out.ive -l 1 The temporary files are produced when it needs to reproject the source data. As you mention they just get dumped in a local directory, while they'd be better off placed in a single directory and/or clean up after the run. Its useful not to clean up after the run though as if you re-run the build you can use the reprojected files as sources instead of the original files and thus avoid reprojection. With modern VPB this whole temporary reprojection has been dealt with in a better way using vpbcache, but its a manual system that you have to invoke vpbcache to prep your data, getting it to do all the required reprojections etc, once the cache is populated the resulting cache file that describes all the data and their reprojections can be used as input to osgdem/vpbmaster and these will then pick files from the cache according to the projection of the sources they need.

Re: [osg-users] observer_ptr get() return type issue
Hi Will, This isn't really a bug, rather just an implement decision that I made on implementing the obersever_ptr. It is however inconsistent with ref_ptr, which was originally like the oberserver_ptr but I believe I probably relaxed this long ago when coming up against issues of const ref_ptr and no const pointers they were managoing - std::setref_ptr is one such awkward instance. FYI, ref_ptr is a very early addition to the OSG, while observer_ptr is quite recent addition so hasn't had the same exposure to problems that the ref_ptr has had to deal with. Reflecting on things now I think it makes sense the observer_ptr should keep the same behaviour as ref_ptr in the case of the various const dereference/get methods, so I've tweak the observer_ptr so that it now passes back T*, T for the const get(), operator*() and operator-() methods. This will be in OSG-2.3.5 dev release that I'll make this morning. Robert.

If the pointer is pointing to a const T*, then the return type would be const without modifying the return type of get(). Is this a bug, or is observer_ptr designed this way for some reason?

I can't speak for Jeremy Moles (the author of osgWidget) about timing, he does mention the above intentions, but he is busy and coding up osgWidget in his spare time so one needs to be aware of this - he has made an open call for assistance and being open source there are few barriers beyond time and know how preventing others like yourself for pitching in. As a general note, with open source projects its good practice to release early and often, so you get a very early glimpse of what a project is like, even both its fully designed let alone implemented. This might seem a bit like a half made bed, but the beauty development wise is that actual users can try it out and spot deficiencies or better solutions to problems very early in the life of project, and well before its gone down any paths of no return. The OpenSceneGraph itself is a project where releasing early, years before 1.0 was made in fact, actually help members of the community get involved direction of the project, it made a huge difference to the robustness and quality of the design having real users testing and debugging the design and implementation as it was evolving - it meant that we had a very good hit rate on solving tasks that end users had to solve, rather than just hitting bullet points on a marketing chart. W.r.t integration with the core OSG, the exact timing I can't say, this is down to how the software itself evolves during the next few months and the availability on engineers (there is a constant eb and flow of how busy we are on different tasks). However, I wouldn't worry about this, getting fixated on a particular merge with the main OpenSceneGraph distribution won't actually make much difference to osgWidget itself, it's open source already - you have all the software required to make it work, and being a NodeKit it'll just slot into the OSG at the right time with minimal fuss. Also, there is a possibility that I will be available to help in order to accelerate the release, but I am not sure how this works. Who do I contact?

Re: [osg-users] Testing of SVN version please
Hi Tony, Thanks for the feedback. I'm aware of the threading issue in osgGA::StateSetManipulator, its easy to fix by setting the DataVariance of the StateSet it modifies to DYNAMIC, but... this will effectively forces the main thread to wait till the whole draw traversal is complete as the StateSet it modifies decorates the whole scene graph. This is rather a heavy impact for just occassionally responding to a key press so I'm looking for a solution that avoids this impact. While I wait for feedback on the OSX I'll ponder on this issue so more to see if I can come up with quick solution, but it may well be something that requires more extensive changes beyond StateSetManipulator and hence more time so would have to wait till after 2.3.5.

I've implemented a solution to the threading issue in StateSetManipulator. The solution is to clone the StateSet before modifying it, and reassigned this cloned StateSet to the parents of the original StateSet. This process effectively disconnects the original StateSet from the scene graph but otherwise keeps all its variable in tack - so the that the draw traversal that will be running in parallel with the updates (when multi-threaded) will not be affected as it's got its own ref_ptr to the StateSet. My testing at this end suggest that the fixes is solid. If things work out this is possible solution that I could add directly to StateSet, providing a convenience function for doing this cloning and reassignment.

[osg-users] RE OSG to Multi-Gen Creator...
Hi Robert and Gordon, Many thanks for the responses. I think I failed to make my problem clear. Sorry. I have an OSG scene. My client needs to load this into Creator to do some additional work on it. Once he has finished his work, he exports to FLT from Creator, and runs osgconv to convert it to an IVE file. I'm looking for a means of doing the transfer from OSG to Creator. The rest is already sorted. Whilst the FLT export pluggin was being developed I hoped to achieve the export from OSG to Creator via another format. My colleague looked at .obj but the results from the OSG export weren't good (apparently - though I haven't seen them myself). I don't think we tried the COLLADA, but given your response, Gordon, I suspect I'm not going to be successful there. Looked at Polytrans as we already have a version here, but didn't spot any support for COLLADA. Thanks for your help on this.

[osg-users] RTT and multi-pass rendering
Hi, I'm now developing rendering software and need RTT and multi-pass rendering. A box in scene contains volume data to render. Here is volume rendering process: Pass 1: Render Scene with box front face render, to textureFront. Pass 2: Render Scene with box back face render, to textureBack. Pass 3: Subtract back face from front face to get textureRayLengh. Pass 4: Render box. So I need RTT and multi-pass rendering technology in OpenSceneGraph. My idea about this question is: use two PRE_RENDER camera to render textureFront, textureBack and one PRE_RENDER camera to render textureRayLength. And a regular camera to render the box. I've look into osgFX and found that could solve my problem by defining three passes for the first three passes, then a individual camera to finish the last job. And my question is is there a simple and fast way to do these?

Hi Robert and Gordon, Many thanks for the responses. I think I failed to make my problem clear. Sorry. I have an OSG scene. My client needs to load this into Creator to do some additional work on it. Once he has finished his work, he exports to FLT from Creator, and runs osgconv to convert it to an IVE file. I'm looking for a means of doing the transfer from OSG to Creator. The rest is already sorted. Whilst the FLT export pluggin was being developed I hoped to achieve the export from OSG to Creator via another format. My colleague looked at .obj but the results from the OSG export weren't good (apparently - though I haven't seen them myself). I don't think we tried the COLLADA, but given your response, Gordon, I suspect I'm not going to be successful there. Looked at Polytrans as we already have a version here, but didn't spot any support for COLLADA. Thanks for your help on this.

[osg-users] Debug JPEG plugin issues
For some time now, I've been unable to load the Debug JPEG plugin osgdb_jpegd.dll. The Release build works just fine. Because I'm on Windows, I had assumed this was some runtime library / PATH issue Today, this finally bugged me enough to investigate it. I looked at osgdb_jpegd.dll the old depends.exe (from VC6 days) and it doesn't indicate any problems. And indeed it turns out it's not a DLL issue, apparently. It seems to be a problem with the 3rdparty binary libjpegD.lib. If I have the CMake variable JPEG_LIBRARY_DEBUG set to libjpegD.lib, then the resulting Debug JPEG plugin refuses to load. On the other hand, with JPEG_LIBRARY_DEBUG set to libjpeg.lib, the Debug JPEG plugin loads and runs just fine. As luck would have it, Mike Weiblen and I are having breakfast tomorrow, so I'll ask him if he knows anything about why this would be happening.

Re: [osg-users] OpenSceneGraph-2.3.5 and VirtualPlanetBuilder-0.9.6 dev release tagged.
Hello Robert, Both these projects are nearing the point that I could probably do OSG-2.4 and VPB-1.0 release quite soon, feature wise I feel they both are pretty near feature complete enough to go with a stable release, so its really about making sure they are robust enough and compile properly across platforms. If these dev releases look reasonable then we could possible go for a stable release of both projects in the next week or two. One thing I'd really like to see before a stable release is done is to make sure any osgShadow weirdness is behind us, that it behaves predictably at least in --sm mode, if not --pssm as well (which looks harder to debug to me). I'm sure many others are in the same situation I am: I can keep up with SVN on my personal machine, but we can't ship SVN or even developer releases to clients. So I would really like shadowing to work in 2.4 as opposed to pushing it off till 2.5.0 or something like that. I think shadowing is the only area that's a bit dodgy right now, so I would really appreciate it if some of the really shadow-savvy people would make a blitz and try to fix the issues to make the issues go away. I can definitely help on the testing side, but my shadow expertise is a bit limited (for now) to the theoretical algorithms, so I can't really debug the OSG implementation of them myself... Sorry about that. I know one of the people who can help in this is Wojtek Lewandowski. This is pretty much a plea for your cooperation, Wojtek :-) Even if you can't integrate LisPSM on time for 2.4, if at least SM works predictably (and as a bonus, PSSM), we would really appreciate it. I realize I'm making demands and not offering much (other than my time as a tester) and the issues might be bigger than I think they are, but it would really help us if this were sorted for 2.4. Thanks in advance to anyone willing to chip in on this.

and the window matrix. I used the following piece of code in my pick event
handler.
protected unsafe bool pick(OsgGA.GUIEventAdapter ea, OsgViewer.Viewer viewer)
{
..
picker = new
OsgUtil.LineSegmentIntersector(OsgUtil.Intersector.CoordinateFrame.PROJECTION,
ea.getXnormalized(), ea.getYnormalized());
OsgUtil.IntersectionVisitor iv = new OsgUtil.IntersectionVisitor(picker);
viewer.getCamera().accept(iv);
Osg.Matrix VPW = new Matrix();
if (iv.getWindowMatrix()!=null)
{
Osg.Matrix mm = new Osg.Matrix(iv.getWindowMatrix().ptr());
VPW.preMult(mm);
}
if (iv.getProjectionMatrix() != null)
{
Osg.Matrix mm = new
Osg.Matrix(iv.getProjectionMatrix().ptr());
VPW.preMult(mm);
}
if (iv.getViewMatrix() != null)
{
Osg.Matrix mm = new Osg.Matrix(iv.getViewMatrix().ptr());
VPW.preMult(mm);
}
if (iv.getModelMatrix() != null)
{
Osg.Matrix mm = new Osg.Matrix(iv.getModelMatrix().ptr());
VPW.preMult(mm);
}
..
}
But the iv object could never return any matrix and all the Boolean expression
in the if statement always equal to false.
I'm wondering what is wrong here. Is there any thing else that I need to do
before I can obtain the matrices?
Any help is appreciated!
Regards,
Ke Li

[osg-users] A simulation project
Hi guys, iam a final year computer science student and i want to do a project on Simulation of the faculty's building resources. Iam interested in simulating the resources available at the faculty(labs and classrooms) to find out if they could handle a larger number of students or in case new courses were added to the curriculum. My question is could i be able to use OSG? Iam quite new in the field of OSG and would luv to learn more. Thanx Harold ___ Rise to the challenge for Sport Relief with Yahoo!

[osg-users] OsgDotNet
Hello All, We are using OsgDotNet and noticed a couple of things we would like to ask about. 1. We noticed that the quat multiply is not exported in .NET. We saw that this was because of the OsgIntrospection not properly exporting some of the overloaded operators, so there are probably other ones besides quat multiply. We were going to go ahead and implement it ourselves, but I wanted to see if there was some standard way people were using to provide for themselves these kinds of operators. 2. We have some code that was written in straight C++ and OSG, building some scene graphs we would like to include. We WERE using Managed C++ and our own OSG kinds of wrappers to make that interop work. Now we are moving over to OsgDotNet and we were looking for a way to wrap stuff written in C++. Any way to do that? Thanks, -- Rick ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] game like movement
Hi Seppo, Actually, It could be. But I don't know any example like your description. So you have to specify an related osg examples. For example you can get a mouse coordinates from osghanglide example. In that example terrain model was rotated by mouse directions. And the second part of your description is moving by using forward (like directional buttons) button. It was normal osgGA keyboard controlling. You can find lots of keyboard controlling code part in osg examples. I thing that information would be benefical. Good Luck!

This means, that I can use mouse to look around and move with arrow keys – forward arrow key moving to direction I am looking with mouse. From the example files I found only one kind of movement, and not this kind at all.. Thanks in advance!
