Re: [osg-users] osgVolume development report?
Hi Robert, Thank you for your reply. I will check this mailing list frequently for further developments. If you need beta testers for the osgVolume NodeKit, I guess I could be one (compiling problems, performance testing and other funny tasks). bye.

This week I'll be spending a day porting the volume rendering functionality from the osgvolume example into osgVolume, this will serve as the basis for osgVolume for the OSG-2.8 release. It won't be too sophisticated, just basic shader based ray tracing and iso surface rendering. A big chunk of osgVolume is the Dicom loader, and this is already available in svn/trunk, although used in conjunction with the osgvolume example right now rather than generate osgVolume nodes, although for 2.8 this should be available.

[osg-users] NodeTrackerManipulator
Hi, I notice when I toggle the TrackerNode of the NodeTrackerManipulator between NODE_CENTRE and NODE_CENTER_AND_ROTATION during runtime, the camera view will have a sudden jump from one view to another. Does anyone face such issue? Is there anyway to prevent such a jump? Thanks Regards ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] osgNV 0.6.2 released, with a preliminary physics support!
Hi all, osgNV 0.6.2 has been released today, with the integration of the latest Cg 2.1 runtime, including a new resource manager, new profiles, the support of geometry shaders, new sampler uniforms class (cgGLSetTextureParameter), new buffer uniforms class (cgSetBufferParameter) and related examples. Another important feature of the new release is a preliminary integration of OSG and PhysX libraries, which makes it possible now for OSG developers to implement collidings, rigid and soft objects, cloth and clothing, fluids and many other physics simulations. PhysX is one of the most famous physics engines and also part of the nVIDIA functionalities. The new module, named osgNVPhysx, is going to support the nVIDIA PhysX and even more physics engines (like ODE, Bullet, Newton and so on, because of its open structure in design) step by step! Creation and computation of rigid actors are provided at present, as the attached image shows. The website is: http://osgnv.sourceforge.net/ You may download the latest osgNV tarball at: https://sourceforge.net/projects/osgnv/ The SVN access is also usable: *svn co https://osgnv.svn.sourceforge.net/svnroot/osgnv osgnv* Already tested on Windows XP SP2, Visual Studio 2008. You will need OpenSceneGraph, CMake, nVIDIA Cg ( http://developer.nvidia.com/object/cg_toolkit.html) and nVIDIA PhysX ( http://developer.nvidia.com/object/physx.html) if you want to see all the latest features. BUILD_PHYSX (the new physics engine support) is off by default in CMakeLists.txt, and the osgNVPhysx module has not yet tested on GNU/Linux systems. Could anybody help me test it? Thanks for advices and suggestions. Cheers, Wang Rui attachment: osgnvphysxboxes.JPG___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] please test... SSAO (v1.0)

The code was missing three ref_ptr .get()s, so I guess you didn't compile

I don't know much about these things myself as I've only been using a Mac for about 1 day now but this blog entry details the issue http://www.red-sweater.com/blog/246/missing-link As far as cmake goes, and I've only been looking at _that_ for about 2 days, it seems the problem is in the top-level CMakeLists.txt file where it has the line FIND_LIBRARY(MATH_LIBRARY m) wrapped in an IF(UNIX) clause. I think this particular line should also be wrappend in an IF(NOT APPLE) clause. Doing this fixes up the link lines for me and the problem goes away. As I say I'm certainly no Mac expert so maybe this isn't quite right.

Re: [osg-users] Precipitation effect coming too fast, and hiding on some areas
Hi Robert Jefferson,
- Jefferson Pinheiro a écrit :
2) Use an osg::ClipPlane to clip the precipitation effect. Using a
clip plan would also allow you to control angle of the clipping.
I don't know how to use that (I'm a beginner). Fred, I would be
grateful if you could share your code, if you do it.
Unfortunately, it doesn't seem to work ( at least for me ). I modified the
osgprecipitation example to add a simple clip plane, and although the model is
clipped, the rain continues to appear in the half space clipped.
Attached the modified example.

Re: [osg-users] Light Position Behavior
HI Ryan, It's the CameraManipulator that will be setting the view matrix per frame, and it is what is using the bounding volume of the scene graph to set it's initial position. If you have a camera manipulator attached to the viewer on end of each update traversal the view matrix from the camera manipulator will be copied to the camera's view matrix overwritting what you are setting manually, unless you do it after the updateTraversal() (note frame() encompasses advance(); eventTraversal();updateTraversal();renderinTraversals()); If you want to use Camera::setViewerMatrix*() methods then you to need to create your viewer without attached a CameraManipulator, and by default this is what the viewer does unless you call viewer.run() as viewer.run() has a fallback of attaching a TrackballManipulator is nothing else is setting the camera viewer matrix. If you call viewer.realize() and run the frame loop yourself then you won't get this auto added camera manipulator. My guess is that you still might be happy using the CameraManipulator if only it didn't use the whole bounding sphere. For this you can just use: viewer.getCameraManipualtor()-setHomePosition(eye, look, up); But you'll need to call this after the setSceneData() as this it'll be the setSceneData() that is prompting the camera manipulator to do it's stuff. You follow up email about setUpViewerAsEmbeded() is just a distraction, it's not related to the problem in hand. Robert.

[osg-users] osgManipulator Dragger Handler get transformation decal
Hi, Using the draggerHandler (the copy of the one in osgManipulator example) to rotate and translate a node, I need to get theses transformations to apply it to an other node. In the Handler, I get the previous matrix of the dragger, and after transformation (on release) I get the other matrix. If I print the values : * DISPVECT(relative trans, afterMoving.getTrans() - _beforeMoving.getTrans()); DISPQUAT(relative rot , afterMoving.getRotate() * _beforeMoving.getRotate().inverse());* It looks very good. Next, to apply theses transformation to an osg::Plane, I use this code : * osg::Vec3d trans = afterMoving.getTrans() - beforeMoving.getTrans(); osg::Quat rot = afterMoving.getRotate() * beforeMoving.getRotate().inverse(); //Create the transformation matrix to rotate and translate the plane. the plane has its center int the center of the Dragger osg::Matrixd m ; m = osg::Matrixd::translate(-beforeMoving.getTrans()) * osg::Matrixd::rotate(rot) * osg::Matrixd::translate(beforeMoving.getTrans()) * osg::Matrixd::translate(trans); DISPVECT(relative plane trans, m.getTrans()); DISPQUAT(relative plane rot , m.getRotate()); myPlane-transform(m);* The value applied are not the same ! values returned : *relative trans : 0 0 0 relative rot : 1.63503e-008 -0.461046 2.45062e-008 0.920392 relative plane trans : 3081.37 -7.26342e-005 -3422.35 relative plane rot : 1.58832e-008 -0.447874 2.38061e-008 0.894097* The translation result looks good, but the rotation is not exactly the good one... Do you have any idea of where to find why there is a difference ? May be a math problem, or a plane-transform not adapted to that kind of computation ... ? Thanks a lot.

Hello Kimmo, Adrian, The code was missing three ref_ptr .get()s, so I guess you didn’t compile the version you attached… The SVN version now includes an implicit conversion operator from ref_ptrT to T*, so it is now possible to code without calling get() to pass a pointer from a ref_ptr. I guess Adrian has started using this, but you have an older version of OSG which does not include this...

Re: [osg-users] osgNV 0.6.2 released, with a preliminary physics support!
Hello Wang Rui, Nice job, you seem to be progressing nicely with this! I have one small comment: The new module, named osgNVPhysx, is going to support the nVIDIA PhysX and even more physics engines (like ODE, Bullet, Newton and so on, because of its open structure in design) step by step! If you intended it to support other physics engines that PhysX, I think osgNVPhysx is probably not the best name... osgPhysics would be better, as has been suggested in the past, with concrete bindings for PhysX (which could then be in another module named osgNVPhysx if you want) and any other engine people want to implement. Other than that, good work, keep it coming!

Re: [osg-users] multiple graphics contexts hurting performance?
Hi Joe, Yesterday, I setup a new system with 2 GeForce GTX 280 cards and four monitors. The OS is Vista x64. I just read your previous posting and I can confirm the exactly same problems. Now I am about to install XP (and Ubuntu) to see if it runs better with four monitors there. Have you done any more discoveries since you wrote this mail?

HI Paul, The core OSG library does link against the MATH_LIBRARY, but the other non of the other core libraries do. I've added a entry of MATH_LIBRARY into the linking of osgText. Could you do an svn update and see if the error is fixed?

Re: [osg-users] multiple graphics contexts hurting performance?
Hi Joe, With the cull and draw going sky high it very much looks a driver bug to me. In my own PC based mutli-GPU testing I've found that serializing the draw dispatch helped performance, so made this the default but you can override this using the env var: OSG_SERIALIZE_DRAW_DISPATCH set to OFF. A couple of days ago I did try to set up my new Core i7/X58 system up with two graphics cards but the kernel/NVidia drivers couldn't initialize themselves properly so I wasn't able to boot. I was just using the NVidia driver pulled down for Ubuntu repositories so this might be part of the problem, or it could be that I have see a bleeding edge hardware setup that the kernel/drivers haven't caught up yet. Frustratingly this system hardware wise is most capable of doing scalable multi-GPU work, but right now I don't have the time to go routing around for a solution so can't test multi-gpu setups right away. My previous workstation also supported dual GPU but a broken disk on it means that right now I'm just working on my new machine and without the ability to test dual GPU. Robert.

Re: [osg-users] osgManipulator Dragger Handler get transformation decal
I'll try to simplify the problem, because I think it is not easy to understand what the problem looks like. (I know I need to wait ... but it become urgent so I still stay trying ideas or waiting for yours) Group | |_ || | Dragger1 Selection1 Plane | _| || Dragger2 Selection2 | Geode Dragger 1 is translation, Dragger2 is rotation When I use/dragg Drager2, Selection 2 changes, and the node rotate. What I need, is to get the transformation applied on the Geode, to set the same on Plane. (same place, same orientation) In the DraggerHandler, I get the Selection2 when rotating. So I copy matrix before and after rotation to compute the rotation done and apply it to Plane (osg::Plane). So I do : osg::Matrixd m = osg::Matrixd::translate(-afterMoving.getTrans()) * (afterMoving * osg::Matrixd::inverse(beforeMoving)) * osg::Matrixd::translate(afterMoving.getTrans()); Plane-transform(m); (because Plane is not a geometry, no Transform can be apply on it.) But the plane and the Geode not have the same orientation... I don't understand where the calculs are wrong. Thanks. Regards, Vincent. 2008/12/18 Vincent Bourdier vincent.bourd...@gmail.com Hi, Using the draggerHandler (the copy of the one in osgManipulator example) to rotate and translate a node, I need to get theses transformations to apply it to an other node. In the Handler, I get the previous matrix of the dragger, and after transformation (on release) I get the other matrix. If I print the values : * DISPVECT(relative trans, afterMoving.getTrans() - _beforeMoving.getTrans()); DISPQUAT(relative rot , afterMoving.getRotate() * _beforeMoving.getRotate().inverse());* It looks very good. Next, to apply theses transformation to an osg::Plane, I use this code : * osg::Vec3d trans = afterMoving.getTrans() - beforeMoving.getTrans(); osg::Quat rot = afterMoving.getRotate() * beforeMoving.getRotate().inverse(); //Create the transformation matrix to rotate and translate the plane. the plane has its center int the center of the Dragger osg::Matrixd m ; m = osg::Matrixd::translate(-beforeMoving.getTrans()) * osg::Matrixd::rotate(rot) * osg::Matrixd::translate(beforeMoving.getTrans()) * osg::Matrixd::translate(trans); DISPVECT(relative plane trans, m.getTrans()); DISPQUAT(relative plane rot , m.getRotate()); myPlane-transform(m);* The value applied are not the same ! values returned : *relative trans : 0 0 0 relative rot : 1.63503e-008 -0.461046 2.45062e-008 0.920392 relative plane trans : 3081.37 -7.26342e-005 -3422.35 relative plane rot : 1.58832e-008 -0.447874 2.38061e-008 0.894097* The translation result looks good, but the rotation is not exactly the good one...

Re: [osg-users] osgNV 0.6.2 released, with a preliminary physics support!
Hi J-S, Thanks! I'm just wondering to move the base classes of osgNVPhysx into another namespace, and hatch out more integrations from that, like osgODE, osgBullet, etc. Members of the base classes, which are not associated with any physics engines but support most common interfaces to them, include a singleton manager class, an abstract builder (inherit to initialize/destroy the engine), an abstract scene (manage the scene), and elements of the scene (rigid, soft bodies, joints, cloth, fluid...). I will start to create that osgPhysics namespace and try to make it open and expandable to most physics engines. Hope a simple framework be done before the Chinese spring festival :-) But it seems not part of the osgNV library any more?

Is there are ATI / NVidia specialiste to support me locating the

Hi Adrian,
This looks very nice! Could you give a little more background info? Did
you use the nvidia paper as starting point? E.g. I am curious if this
technique is applicable for large outdoor environments.
Thanks a lot

Hi Robert,

mutlipass-rendering when we don't resize the window, actually 512x512. so
what sould i do, to replace this issue. ?
Another thing is to remove the last pass GLSL shader, is there a way to
solve it under common openGL textureing? Mutlitextureing? Or any other
idea.
This version supports:
(Transparant faces: just disable for transparent faces like window,
glass the detph writing, the depth buffer will hold only un-transparent
z-values (alpha 0.9) )
toggle ssao on/off with key 'a'
have a look and i will be happy to get any ideas to improve the stuff.

Re: [osg-users] Particle system setInitialRotationalSpeedRange()
Hi Erik et. al, I have now fixed osgParticle to behave as it did before w.r.t particle rotation. The fix is now checked in to svn/trunk. I reviewed the changes from Tom, but these would have broken other functionality so I re-factored ParticleSystem::single_pass_render() and Particle::render() methods so that the rotation implementation moved out of the lower level Particle::render() into the single_pass_render() function. With this change I also made the rotation so that it was done in eye coordinates, and made the rotation operation optional so the cost of computing the rotation matrix was only applied to particle systems that actually needed it. This change should speed up particle systems that don't use rotation. In investigating this issue I found that the concept of particle rotation is actually broken in osgParticle, as the particle rotation really should be done in object coordinates not in eye coordinates, however billboard doesn't mix well with such a model without doing something clever with projecting the rotation from local to eye coordinates. I will cross this bridge another day though, for now I've implemented the original, if somewhat conceptually broken, behviour. Could you try out svn trunk to see if this fixes it. Cheers, Robert. On Thu, Aug 21, 2008 at 12:07 AM, Erik Johnson r.erik.john...@gmail.com wrote: Hi all, It seems to me, back in the OSG 2.2.x time frame, that I could set the initial rotational velocity of the RadialShooter and have the particles pinwheel around their center point, while maintaining their billboard orientation and face the Camera. Perhaps it was a rotation on the Y axis. Nowadays with OSG 2.4/2.6, setting the rotational speed will cause the particles to rotate relative to the world axis and not in the camera-relative axis. Is this a bug? A feature? Is it still posible to pinwheel a particle around? Does anyone use setInitialRotationalSpeedRange()? This was a cool effect which added a nice dimension to smoke plumes and such.

Hi Robert, Thanks for looking into this. --- On Thu, 18/12/08, Robert Osfield robert.osfi...@gmail.com wrote: snip The core OSG library does link against the MATH_LIBRARY, but the other non of the other core libraries do. Apparently not on MacOSX using cmake :) Take a look at src/osgText/CMakeFiles/osgText.dir/link.txt without the change you just made. In fact take a look at any of the link.txt files for each OSG library. Thay all have /usr/lib/libm.dylib in there. I've added a entry of MATH_LIBRARY into the linking of osgText. Could you do an svn update and see if the error is fixed? I got the svn version and no it doesn't fix it. All it does is move the /usr/lib/libm.dylib reference on the link line to a different place! The fact you've got errors but others under OSX haven't reported this (including myself) suggests that must be something else going w.r.t gcc/SDK's you are using on your machine. I'm sorry I haven't explained this well enough. The goal here is to *not* have any explicit reference to libm.dylib on the link line. The symbols reside in the SDK version of the library at /Developer/SDKs/MacOSX10.4u.sdk/usr/lib/libm.dylib and *not* necessarily at /usr/lib/libm.dylib which is what the MATH_LIBRARY is set to. This is fine for UNIX but not Mac as it should be the former that is used for a consistent build (if there are Mac developers out there who disagree please correct me - I'm new to this). By omitting the explicit reference to libm.dylib the Mac build system takes care of this automatically and gets the symbols from the SDK version of the library. Users who are not seeing this problem have all the symbols they require in /usr/lib/libm.dylib and are, as I understand it, lucky ;) Paul Robert.

The link to the blog entry in my first email explains this better than I can. As I understand it, the systems that work are simply getting away with it as the symbols required by the build process just happen to be all there in the system libraries.

[osg-users] High resolution screencast
Hi, I apology in advance if this thread have been heavily answered before (if so just tell where I can find the solution). Still I would like to know the different alternative (the good ones) to record a video of my scene. So far I was using an external tool for screenCast (called istanbul). But I'm not satisfied by this because when my scene is very complex, my osg based application is lagging and this leads to a poor quality of th video. I'm especially interested if there is a way to create an RecordCameraPathHandler to record a path, and then instead of saving it as a .path file compute the video in a batch mode. By batch mode I mean that the creation of the video doesn't need to be real time. In that way I could hopefully control the lag effects and eventually the resolution of the video.

Re: [osg-users] High resolution screencast
Hi Simon, I think your system is UBUNTU. Because I tried İstanbul deb package before :) I don't think batch video creation would be easy and effectively. Because created path by RecordCameraPathHandler is only the movement of objects on the screen. So after you run program by using path record, rendering will be the same amount of overloading on graphics card. So you can use external video camera to capture application vid. I have tried video camera way and it's most effective :) Regards. 2008/12/18 Simon Loic simon1l...@gmail.com Hi, I apology in advance if this thread have been heavily answered before (if so just tell where I can find the solution).

Re: [osg-users] High resolution screencast
Hi Simon,
I got a solution for you, which is not an out-of-the-box one and requires a
little coding, but I already did a similar thing to capture the output of an
OpenGL/SDL app and it worked properly:
You may tweak the main loop and control yourself the simulation time of the
scene graph. That way, you could render and capture a constant frame-rate video
(25fps for example). The video rendering is then not realtime: if your PC is
fast, the redering will last less than the video, but the video itslef would
always have a constant frame rate. Here is my solution in pseudo-code:
while( !viewer.done() ) {
videoTime += 1/25.f; // Advance 1/25th of second
viewer.frame(videoTime); // ... and tell the scene graph
Capture the rendered image
If you have an API for compressing video, send the captured image to it.
Else save it to disk for manual encoding.
}
Hope it helps.

Hi,
I apology in advance if this thread have been heavily answered before (if so
just tell where I can find the solution). Still I would like to know the
different alternative (the good ones) to record a video of my scene.
So far I was using an external tool for screenCast (called istanbul). But
I'm not satisfied by this because when my scene is very complex, my osg
based application is lagging and this leads to a poor quality of th video.
I'm especially interested if there is a way to create an
RecordCameraPathHandler to record a path, and then instead of saving it as a
.path file compute the video in a batch mode. By batch mode I mean that the
creation of the video doesn't need to be real time. In that way I could
hopefully control the lag effects and eventually the resolution of the
video.
Sincerely,

[osg-users] osgDB::DynamicLibrary dlopen flags?
Hi Robert, not sure if you followed my discussion with Jose-Luis regarding osgLua and the problem of stripped RTTI - actually I figured I was barking up the wrong tree. osgIntrospection wrappers will not work on dlopen based systems with gcc 3.x as the osgDB::DynamicLibrary has hardwired the RTLD_LAZY flag in there. Is there a chance that we can get the possibility to set these flags in order to use the introspection. For the time being I need to implement my own loader.

[osg-users] Memory management in OSG
Hello all,
I am currently chasing memory leaks in our application, which is like a
modeling tool where the user will open/work on/save/close data files
multiple times during the same application run. What we are seeing is
that when a file is closed, not all memory related to scene graph
objects seems to be released.
First question:
I enabled the DEBUG_OBJECT_ALLOCATION_DESTRUCTION define in
src/osg/Referenced.cpp, and have set up a small test which just creates
two viewers one after the other in different scopes. Pseudocode:
int main(int argc, char** argv)
{
int bob = 1;// breakpoint #1
{
osgViewer::Viewer viewer;
osg::ref_ptrosg::Node loadedModel =
osgDB::readNodeFile(cow.osg);
viewer.setSceneData( loadedModel.get() );
viewer.run();
}
bob = 2;// breakpoint #2
{
osgViewer::Viewer viewer;
osg::ref_ptrosg::Node loadedModel =
osgDB::readNodeFile(cow.osg);
viewer.setSceneData( loadedModel.get() );
viewer.run();
}
bob = 3;// breakpoint #3
}
What I see is this (all in debug):
Breakpoint #1 :8 Referenced objects, 12MB
First viewer run : ~505 Referenced objects, 266MB
Breakpoint #2 : 247 Referenced objects, 167MB
Second viewer run : ~505 Referenced objects, 266MB
Breakpoint #3 : 247 Referenced objects, 172MB
But then, when I pass breakpoint #3, all the destructors for those
Referenced objects are called, and at the end no objects are left
allocated. (I can see that the final number of objects is 0)
Other than seeing that there are no real leaks per se, my question
about that is, what are those objects that are staying alive outside the
scopes? I would have thought that most objects would only live in one of
the viewer scopes above, 247 seems pretty large to me...
Second question:
Our application apparently has memory leaks, because when closing a file
and opening the same one again, the application takes about 20MB more
each time (i.e. memory usage is ~100MB with a file open, then ~50MB when
it's closed, then ~120MB when it's opened again, then ~70MB when it's
closed again, then ~140MB when it's opened again, and so on).
However, running IBM Purify on the application reveals no massive leaks,
only a few false positives. Are there any tools or techniques that
someone could recommend to make finding and fixing memory leaks easy,
and which work well with OSG? I tried Visual Leak Detector which is open
source, but it reported so many false positives related to variables
stored in ref_ptrs (over 400) that I gave up on it.
Thanks in advance,
J-S

Hi Jean Sebastion,
If your application run on linux plateform you can try valgrind, it will
give you a lot of informations about leaks and more.
