Re: [osg-users] Read dae files with osg.
You'll need to make sure that you have a dll called osgdb_dae.dll in your plugins folder and that your OSG binary can find it. Generally speaking this problem is caused because you haven't set up the environment variables correctly so OSG can't find it's plugins on the path. Hope that helps, Kim.

Re: [osg-users] How to detect rotating image
Hi Clement, The osgViewer::ViewerBase (base class for Viewer) has a FrameScheme hint for the run() method which enables ON_DEMAND or CONTINUOUS, ON_DEMAND is the approach you'd want. You'll be calling frame() yourself rather than run() so won't be able to utilize this feature, but you should be able to learn from it. Have a look at the ViewerBase::run() method in OpenSceneGraph/src/osgViewer/ViewerBase.cpp, in particular the use of checkNeedToDoFrame() which is used to decide whether a frame is needed or not.

[osg-users] osgUtil::Optimizer and osgSim::DOFTransform with data variance STATIC
We recently discovered that osgSim::DOFTransform nodes were unexpectedly removed from the scene graph by the unconditional use of the osgUtil::Optimizer in osgconv. The DOFTransform nodes were marked by our modelling tool (Max with the osgmaxeporter plugin) as STATIC. Should the optimizer flatten DOFTransform nodes at all, under any circumstances? They carry much more information than a simple transformation matrix, such as the ranges for the DOFs. In our case it was this information that needed to be preserved.

HI Magnus, If you make a Transform node as STATIC then you've told the scene graph that it will never change so will be fair game for the Optimizer. You have two choices if you don't want to have the Optimizer optimize it away: 1) Don't call the Optimizer with the FLATTEN_STATIC_TRANSFORM enabled. 2) Make your Transforms which will be changing as DYNAMIC.

Robert. Hi Robert, Thanks for your rapid answer. I understand perfectly well the way the optimizer works and how to get the desired behaviour in its current implementation. DYNAMIC DOFTransform is the way to go (FLATTEN_STATIC_TRANSFORMS wouldn't work, as these DOFTransform nodes are part of bigger scenes, that do benefit from transformation flattening). I was just trying to see if there was a good reason to ever set the data variance to STATIC on a DOFTransform. But maybe this question is more to the authors of osgmaxexporter. Why does osgmaxexporter unconditionally set the data variance to STATIC? What are the use cases where one would model a STATIC DOFTransform?

Therefore I will ask again... Is there a way to get Release-built OSG libs to play nicely with an app that is built with Debug? Right now if I link with Release-built OSG libs, my app (built with Debug option) doesn't work. If I link with Debug-built OSG libs, things work fine. If I built my app with Release, then it also works fine. Here is an explanation of why this doesn't work... http://msdn.microsoft.com/en-us/library/ms235460%28v=vs.80%29.aspx The article talks about the differences between msvcrt.dll and msvcrversion.dll, but the same problem exists when you mix debug and release runtime libraries. You can't pass a pointer generated by your app in debug mode (using the debug version of the C runtime) to OSG in release mode (using the release version of the C runtime). The key is the C runtime flag sent to the compiler. Either compile everything with /MD (Multithreaded DLL) or /MDd (Multithreaded debug DLL). Mixing them is bad. However, I believe you could build a release build of your app with no optimization and with all debug symbols included. This should allow you to debug your code (though not as completely as a full Debug build) from within a release build. Yeah, this works (sort of). --J ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgUtil::Optimizer and osgSim::DOFTransform with data variance STATIC
Hi Magnus, But maybe this question is more to the authors of osgmaxexporter. Why does osgmaxexporter unconditionally set the data variance to STATIC? What are the use cases where one would model a STATIC DOFTransform? DOFTransforms are a relic of Multigen (Presagis) Creator, and in that software they were the most widely used transform node. Modelers (as you probably know) are fond of putting lots of transforms (and groups) all over the scene graph, to keep things understandable to them, and to make it easier to modify the model later. Unfortunately, there are often many of these transforms that aren't really useful once the models are in the simulation software. So yes, there is a valid use case for static DOFTransforms - transforms that were just put there by the modeler for convenience, but which don't have any use in simulation. Now, I agree with you, the STATIC data variance should not be unconditionally applied. There can be rules to determine when it should be, for example if the DOFTransform does not have any limits. At my previous employer, we had made a custom osgconv which would massage the scene graph before calling the osgUtil::Optimizer on it (I think I mentioned this before on this list). This massage is highly dependent on what you'll be doing with your data, which is why I don't think it would be useful to submit such a thing - OSG provides the tools for you to do the right thing in your situation. But just as an example, our tool would: * Normalize state to expected values (we didn't require artists to set the right filtering or face culling manually, we enforced it in the tools, so that osgUtil::Optimizer's various merge operations could give good results) * Flag nodes as dynamic if we didn't want them optimized away (we had various rules, including if a comment contained Dynamic, if a DOF had limits, etc. * Remove most Group nodes since these just hinder the merge visitors and in most cases, better batching (less draw calls) is more important than better spatial culling. Again, I've talked about these things in the past, and others have shared similar or related advice too. Hope this helps, J-S -- __ Jean-Sebastien Guay jean_...@videotron.ca http://whitestar02.dyndns-web.com/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Testing of OpenSceneGraph svn/trunk in prep for 3.1 dev release
Hi Robert I've had a few compile errors on IOS with everything configured for Float, nothing major. Fixes have been submitted. With fixes I successfully built with XCode 4.2.1 for IOS SDK 5.0, GLES2, run on IPad and IPhone. Also compiled with Apples newer LLVM compiler and everything seems to work fine.
