[osg-users] AnimationPath/Manipulator questions
Hi, I am using an animation osg::AnimationPath to control an object in my scene. I want to use osgGA::AnimationPathManipulator to set my camera pos/orientation. My question is how do I sync the paths. The time step in each animation references the same point in time. Will the animation paths begin at the same time? CD ... Thank you!

[osg-users] Wait for camera to finish rendering
Hello, I am having a compute pipeline (physics simulation) that ends with a camera that renders to an image (for further processing on cpu). I'd like the Viewer::frame() to exit only after the image has been rendered to, so that update traversal happens after the data has been downloaded to image. I am familiar with the workings of Code: setDataVariance(osg::Object::DYNAMIC), but this unfortunately applies to drawables, not the output image. If I set data variance to dynamic, the frame() will wait to process the drawables for the camera node, but exit right after, not waiting for the render to image to finish. The only way I could figure out, to make it wait, is to set up a dummy camera (with dynamic variance) with a render order right after my image-camera. That works, but I was hoping there is nicer solution to this problem that I am missing. I was also considering camera PostDraw callback, but it doesn't really solve the problem, since the downloaded data won't be available in the next frame update travesal. If anyone can share some experience on this matter, I'd appreciate it. Thanks.

I can have a look at it, but what is the recommended way to fix this? The problem is that VRML meshes use the indexed format for the most part, so if the mesh representation has to be converted, that is going to be a major pain. BIND_PER_PRIMITIVE loss is annoying, but can be fixed relatively easily by duplicating the attributes per vertex.

That is normal - the OpenVRML code is chock full of templates and various complex C++ constructions, so the compilation takes ages.

For me it never hung on anything, it just took a while to build. Could you have some system issue? E.g. a latent filesystem problem? The libtool is used only at the very end as far as I could see, so that shouldn't affect compilation. > > I'm just installed openvrml and now doing an OSG build, safe in the > knowledge that it'll work just fine with parallel build and scream > through each .cpp doing several a second.

[osg-users] Please test svn/trunk in prep for 3.1.8 dev release
Hi All, I will be tagging the 3.1.8 today or tomorrow, there have been substantial changes to the internals of osg::Geometry and associated classes that used the deprecated array indices and BIND_PER_PRIMITIVE binding. These changes are complete yet but are most of the way there in terms of what we'll require for the up coming 3.2 stable release. The extent of these changes means that we'll need testing across as many platforms and against as many models and applications as we can. So... please could the community check out svn/trunk and let me know how well it builds on your platform(s) and any issues that arise. In most cases I expect user applications will just compile and work as before, if you are using the deprecated features then you application should still compile and work with the default build of the OSG, however, you there are some changes that will require code changes to keep things compiling and working. Longer term you'll need to move away from the deprecated features (they've been deprecated for a number of years already.) Let me know how you all get on, good or bad and I'll try and get fixes checked in or provide advice about how you can tweak your application to fix any build issues that might arise in niche cases.

Re: [osg-users] OpenVRML compile failure
Hi Jan, I have got the vrml plugin compiling against OpenVRML0.18.9 and the latest changes to osg::Geometry, albeit still using the deprecated functions. I don't have any .wrl models right now so will let others test the plugin. Longer term the vrml plugin, along with the Inventor plugin will need revisting so it doesn't using vertex indices or BIND_PER_PRIMITIVE, I have plenty on my plate so will have to leave this to others to tackle.
