Re: [osg-users] Rewrite of DatabasePager::removeExpiredSubgraphs(double)

Re: [osg-users] (VPB) osgdem not providing terrain heights with --tile-terrain-size --tile-image-size options
Hi Scott, If you want low res elevation data but high res imagery, and you have high res elevation data and imagery then why not just swop out the high res elevation data for data at the res you want. gdal has tools to changing the res of data, why not try this out. You can use -l to limit levels, and --tile-terrain-size to do something similar but explain how all this works is far more work than doing the above. Robert.

I would like larger terrain trinagles (and regions) at the finest level, but maintain my highest resolution input imagery. For instance, it would be acceptable if I had 400m terrain tiles at the finest res level with 512x512 image tiles. This would equate to .78125 meters/texel resolution. The tile dimensions aren't controlled in size, it's purely done in post dimensions. If you don't need high res heights then just set the --tile-terrain-size size to something like 16 and then limit the number of levels provide using -l numlevels. Scott S.

[osg-users] How to work with Delta3d in MFC SDI ?
Hi, all,
In OSGViewerMFC MDI or SDI, it begin a thread in OnInitialUpdate() of MFC_View:
mThreadHandle = (HANDLE)_beginthread(COSG::Render, 0, mOSG) ,
and in Render(void* ptr) function, it likes this:
while(!viewer-done())
{
osg-PreFrameUpdate();
viewer-frame();
osg-PostFrameUpdate();
}
Well, if i do it with Delta3d in MFC SDI, how to put the Delta3d's function
corresponding to make it work like that ?
I had a try with dtABC::Widget refered to the example testWidget, then i made
it like this :
1. class MyWidget : public dtABC::Widget
2. void MyWidget::InitWinData(HWND hwnd, int x, int y, int w, int h)
{
dtABC::WinData windata( hwnd, x, y, w, h );
SendMessage( dtABC::Widget::msgWindowData, windata );
SendMessage( setpath, path );
SendMessage( loadfile, m_ModelFile );
}
3. void MyWidget::Render(void* ptr)
{
// I don't konw witch function i should put here!
}
4.void CD3DMFCView::OnInitialUpdate()
{
CView::OnInitialUpdate();
m_MyViewWidget-InitWinData();
// Here, should i begin a thread like OSGViewerMFC does in its
OnInitialUpdate() ?
// m_ThreadHandle = (HANDLE)_beginthread(MyWidget::Render, 0,
m_MyViewWidget);
}
Thank you indeed for your patient
Best regardes !!!

[osg-users] Multiple Render Targets - Request for Comments/Testing
Hi, over the weekend I have consolidated previous hacks to enable MRT into what I hope would be an acceptable patch for OSG. I would like to have it tested a bit before sending it to submissions. Attached are the changes to OSG's Camera and RenderStage. Camera got a new method called setDrawBuffers (instead of the normal setDrawBuffer), which mirrors the OpenGL extension glDrawBuffers. setDrawBuffers takes a vector of BufferComponents and this vector is then translated in RenderStage to a vector of GLenums that is passed to glDrawBuffers. The new calls are orthogonal to current use cases, so hopefully no other code/examples would be affected. The attached example shows sample usage. The example is very contrived, but I hope it explains the concept. I have some other examples that I can contribute later. Please let fly with comments/observations. regards jp PS. How do I add an example to OSG? The CMakelists in the examples directory contains a list of directories, but when is the CMakelists in a specific example directory created? -- This message is subject to the CSIR's copyright terms and conditions, e-mail legal notice, and implemented Open Document Format (ODF) standard.

Before I try to understand what's going on, is there anything that I might have overlooked, as for example any optimizations whose default values have changed since OSG 1.2? Check the CMake build options for release vs debug. The other possibility is the default enabling of theadsafe ref/unref for the majority of scene graph objects. I certainly don't see big differences under Linux with enabled - just a couple of percent in cull traversal for big scenes, but you never know the Windows OpenThreads::Mutex might be dog slow compared to Pthreads. You can enable threadsafe ref/unref in 1.2 and find out, its more awkward to disable under 2.x though as a number of objects explicitly set the thread safe ref/unref. The wider use of thread safe ref/unref is what you have to pay for greater stability when multi-threading, and with 2.x threading is much more prevalent once you start using osgViewer. The new threading models should mean you should get better performance once you start utilising them. Robert. I hate taking this thread off subject, but if thread safe ref/unref are causing performance problems you might want to look at how boost does their shared_ptr.

Re: [osg-users] Performance drop higher RAM usage after switchingfrom OSG 1.2 to latest SVN
Hi Robert, Another possibility I missed is the use of doubles in osg::Plane by default, whereas 1.2 used float by default in osg::Plane. thanks for the hint. However, I think the problem could be related to the compile/apply of GL objects instead. If I disable the GLObjectsVisitor that my app runs after loading a new scene, both builds of the application start in similar conditions with little difference in memory consumption. At this point I start moving the camera around, and display lists and textures get compiled as they are displayed for the first time. Here the difference between the OSG-1.2-based build and the newer one becomes clear: the newer one eats much more memory, roughly twice as much, while the amount of data loaded (geometry+imagery) is the same. All textures are DXT-compressed, and they come with mipmaps already stored in the image file (DDS). In order to minimize the influence of other optimizations, I've turned off the UnRefImageAfteretc. flag on all textures. Except for the different version of OpenThreads and OpenSceneGraph, both builds share the same code and 3rd-party libraries. Any other clues?

It generated some (all ?) libs and dlls filles. _ Créez gratuitement votre disque dur virtuel Windows Live SkyDrive ! http://skydrive.live.com___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Performance drop higher RAM usage afterswitchingfrom OSG 1.2 to latest SVN
Hi Robert, To avoid threading problems apparent in 1.2 the OSG-2.x versions initialization the GL objects arrays to a larger default, if you app isn't setting the number of context down to the number you are using then perhaps this is where the discrepancy is occurring.

[osg-users] osg user meeting in Paris
Hi folks, as far as we all already know there will be a training course in Paris from 25 to 30 April. However there were still no information if and where an official user meeting afterwards will take place. Hence couple of questions: 1. Will there be an official osg-user-meeting? 2. Which date and time? 3. Which location?

Re: [osg-users] Performance drop higher RAM usageafterswitchingfrom OSG 1.2 to latest SVN
Hi Marco, Since I am currently struggling with Windows/ OSG FBO / multi monitor / mutlti threaded problems here are my 2 cents: Have you tested with --SingleThreaded option ? In my configuration multithreaded configs usually eat more RAM. However its not twice as in SingleThreaded. I have read somewhere that NVidia OpenGL dirver creates shadow threads for each thread of the application. Maybe these threads duplicate some resources...

Re: [osg-users] Performance drop higher RAM usage after switchingfrom OSG 1.2 to latest SVN
Hi J-S, Err, are you sure about that last one? SVN OSG cannot use the same 3rd party libs as 1.2 (at least, if you used the 3rdParty libs zip that was downloadable from the OSG site). In particular, there were some changes in osgText that made it incompatible with the version of freetype that was included in the old 3rd party libs zip. I'm using the new 3rdParty archive with both versions of OSG. I had to recompile the 3rdParty libraries since the binaries weren't totally compatible with Visual Studio 2008, but that's all.

Re: [osg-users] Performance drop higher RAMusageafterswitchingfrom OSG 1.2 to latest SVN
For now I'm ujst putting some logging code in OSG 1.2 and 2.3 to show the number of compiled GL objects, which I suppose should be the same in both versions. I'll let you know if I find any discrepancies. Here are the results: upon firing the GLObjectsVisitor, the app built with OSG 1.2 calls glGenTextures() 1795 times, while the newer build calls it 2734 times. I'll study the osgViewer code, maybe my viewer is setting up things incorrectly... If so, I wonder why it works fine with OSG 1.2.

The only interesting thing about your class I see is the m_Text object
will have two references: the m_Text member, and the entry in
osg::Geode's Drawable list. However, when GLTextString goes out of
scope, both those should disappear and the osgText::Text will be
deleted...
Probably not related, but returning osg::ref_ptr causes extra
reference counting overhead (which can be significant if it happens a
lot, and is even worse when reference counting thread-safety is
enabled). You could just return osgText::Text*.

Re: [osg-users] Memory leaks with osg::ref_ptr
im using visual studio 2003, and im using the following code to detect
my memory leaks:
// Memory leak information
#ifdef _DEBUG
#define DEBUG_NEW new(_NORMAL_BLOCK, __FILE__, __LINE__)
#include crtdbg.h
#else
#define DEBUG_NEW new
#endif
Here is a class that i use to call GLTextString, its still leaking. I
changed the code in GLTextString to look like this: osgText::Text*
GetText(void) { return m_Text.get(); } and it still leaks. In the
following code lines like:
osg::ref_ptrosg::ShapeDrawable drawable = new
osg::ShapeDrawable(cylinder.get(), hints.get());
also leak! So im completely lost with osg::ref_ptr thing now. Again

I found that if i do not load the dlls using mangled names(the plugins i'm using are: ive/png/freetype/tga), that's ok, so i think the problem may lies on the loading and deloading the plugins, maybe memory free, any ideas? thanks a lot! shubo ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
