Re: [osg-users] animtk release 0.0.9
Hi Sukender, I have same problem under Windows. If you achive, please show how. And another question to Cedric and Robert, In which version osganimation library will be added ? Best Regards. Umıt Uzun 2008/11/1 Sukender [EMAIL PROTECTED] Yes i guess i would need to add export in order it compiles on windows. Hum... I'm interested in using animTK in a cross-platform way... I tried to CMake-it under Windows but it can't find pkg-config (of course). I guess the CMake script has to be changed, but I'm new to CMake and I can't. I will try to bybass that problem. If I get something compiled under Windows, I'll let you know. But if anyone did it before, please tell me!

Re: [osg-users] animtk release 0.0.9
2008/11/1 Ümit Uzun [EMAIL PROTECTED]: Hi Sukender, I have same problem under Windows. If you achive, please show how. You guys are probably the first to run AnimTK under Windows, a port to windows will take the addition of exports as well possible tweaks to CMake. And another question to Cedric and Robert, In which version osganimation library will be added ? My last proposal was for Cedric to coordinate with Jeremey on integrating AnimTK into Jeremey's osgWidget dev branch in OSG/svn/branches, at this integration point the new NodeKit name would be osgAnimation. This branch would then need to be tested and shook down before integration from this experimental branch into svn/trunk. You can browse the branch via: http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/branches/OpenSceneGraph-osgWidget-dev Or check it out with: svn co http://www.openscenegraph.org/svn/osg/OpenSceneGraph/branches/OpenSceneGraph-osgWidget-dev OpenSceneGreaph-osgWidget-dev I quick browse just now suggests that Cedric hasn't yet merged AnimTK/osgAnimation. I'll have to defer to him for his own plans on completing this. As to whether osgAnimation will be merged with before 2.8 or after will depend on whether it how well it ports across platforms and how quickly it converges to a functional and stable enough state to make it in. The more developers pitch in with porting/testing/bug fixing the sooner the merge point could be.

Re: [osg-users] terrain segmentation
Hi Memanth, The OSG doesn't have a feature like the one your describe. We do have VirtualPlanetBuilder that builds paged database that are composed of a quad tree of tiles, the source data for this tool is geospatial imagery and DEMs, but it doesn't build paged databases from polygonal terrain models.

Re: [osg-users] Untextured materials = pure black
Hi Jefferson, When using a shader that expects a texture, you must supply a texture or the result is undefined. I think with most graphics cards the texture read just results in black. So if you want to have models that don't have a specific texture you should: a) use another shader that doesn't do a texture read, or b) set a simple default texture (for example, a 1x1 white texture) on the root node of your scene. - Terry Message: 4 Date: Fri, 31 Oct 2008 23:30:23 -0300 From: Jefferson Pinheiro [EMAIL PROTECTED] Subject: [osg-users] Untextured materials = pure black To: osg-users@lists.openscenegraph.org Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=iso-8859-1 Every material that has no texture associated becomes completely black when I do one of the following: - change the shadow technique from ShadowMap to SoftShadowMap - add any of the GLSL bloom shader I found on the net ( http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=27976postdays=0postorder=ascstart=0or http://www.gamedev.net/community/forums/topic.asp?topic_id=395186) Any idea why this is happening?

Re: [osg-users] Disable self shadows (ShadowMap)
Jefferson, I'm sure that Jean-Sebastien or Wojciech can answer better and more correctly than me, but in the meantime... Firstly, I notice that you are using OSG 2.6. The versatility of the API into the shadowing stuff is much better in the 2.7 versions, and allows you better control over what is being applied, so I recommend you move to that if you can. Secondly, in 2.6 at least, the only flag (castsShadow or receivesShadow) that is honoured by the shadowedScene's subgraph is the castsShadow one. Hence if things cast shadows they will also receive shadows. However, in your example, it is only the default fragment shader applied by the shadow map, in the end, which is shading your cars, so one way around it is to reset/force the fragment shader on your cars to one that doesn't try to do the lookup in the shadow texture. You can't do this at the shadowMap level (as this would then be applied to everything including your buildings), but you can do it to the cars individually. Create a shader - you can use the GLSL in ShadowMap.cpp as a starting point - and then bind it to your car node stateset with the usual methods Hope that helps, David ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] 3D Graphs - edges?
All, I am wondering if anyone has tried to implement a graph edge? i.e. a connection (such as a line) between geodes to make a 3D graph, where the connection derives its properties from the geodes it connects. I need to implement such a connector myself, I'm thinking of making it an actual osg node type (extended either osg::Geode or osg:Group) and hopefully it will be good enough to include in OSG. OpenSG has a NodeGraph::Edge (though I haven't looked at it in detail) so I am guessing other OpenSceneGraph users may want one too and someone may have even started...

Re: [osg-users] Shadows in osgviewerQT ? (solved / patch)
Hi again, please find attached a patch against current trunk that fixes my problems. This patch does the following (in order of the chunks in the patch): - Add a missing include in GraphicsWindowsX11 without which it won't compile on my Mac. - Add a missing include to the osgviewerQt build (taken straight from src/osgviewer/CMakeLists.txt) - Ensure GraphicsWindowsCarbon::WindowData is used with QOSGWidget for Mac builds even on 10.4 and 10.5. Without this change, the widget will use the X11 WindowData struct but the peer will expect a Carbon WindowData struct, leading to a segfault. I'm not sure this is the right fix - it might have to pay attention to other configure-time variables. (I.e. it might not work if you asked for using the X11 peers instead of the carbon peers at configure time) - Extract a WindowPtr from the HIViewRef that QWidget::winId() returns. Without this change, the peer tries to call GetWindowPort on the HIViewRef which returns 0. This was the reason that the window remained white. - Setup the camera only after ViewerQOSG's Qt base class has been initialized. Without this change, the view is wrong (doesn't cover the whole window). - Open the ViewerQOSG window at 30/30 instead of 0/0. When opened at 0/0 it lacks any window decoration (not sure why that is so - might be a Qt feature?) I hope this helps.

Unfortunately QOSGWidget doesn't work here: the widgets remains white and Qt prints warnings about recursive repaint. I've checked out the latest OSG trunk and tried with that but get the same result (actually it segfaults due to a bogus ifdef in the QOSGWidget source code - I'll send over a patch shortly - but after fixing that I get the same result.) I've started tracking down the problem, so far the only thing that I figured out is that GetWindowPort always seems to return 0 for the QOSGWidget's native peer - is that expected? I'm using Qt 4.4.3 on an Intel Mac with OS X 10.5. The Carbon code paths are used, not X11. Are there any known problems with QOSGWidget with Qt 4.4, OS X 10.5 or with the Carbon peers?

(This is one of the new Intel Macbooks running OS X 10.5) I gather that when embedded in Qt, the GraphicsWindowCarbon code isn't used and osg just uses the existing GL context. Does that mean that I would have to manually setup Qt's GL context and somehow synchronize it with osg's shadow magic?
