Re: [osg-users] [osgOcean] how to set path to other resources folder?
Hi Bart, osgOcean uses the osgDB registry to find paths for resources. You can add additional path to that with the following code: osgDB::Registry::instance()-getDataFilePathList().push_back( resources/boat); There is an example of this in application.cpp http://code.google.com/p/osgocean/source/browse/trunk/src/oceanExample/application.cpp#303 Cheers, Kim.

Re: [osg-users] Frame syncing over multiple contexts
Hi John, On 19 January 2012 20:58, John Kelso ke...@nist.gov wrote: OK then! This is getting good! I tried setting setEndBarrierPosition(BeforeSwapBuffers), setting setThreadingModel(CullDrawThreadPerContext), and running with four windows, each with a single camera, on a desktop system with a single graphics card, and the problem didn't go away. But should the problem go away in this environment? Without swap ready and gen lock you can't perfectly sync the displays. swap ready is a signal that all the rendering on a graphics card has completed and is ready to swap. gen lock is a hardware sync of the refresh itself that ensures that the scan for each display occurs at the same time. You can approximate a swap ready by doing a glFlush() or glFinish() prior to the swap barrier. The osg::BarrierOperation (implemented in include/osg/GraphicsThread) has support for doing either of glFlush or glFinish() prior to joining the barrier, but... currently osgViewer defaults to setting up the BarrierOperation with both of these off, just checking the source I see there isn't a access method for getting the end barrier. You could add this (subclassing from osgViewer::Viewer would give you a way of adding this), once you have the end barrier you'll be able to set the BarrierOperation::_preBlockOp. osgViewer::ViewerBase really should have this built in though so please feel free to add and submit it. Adding a glFlush() prior to the barrier will just make sure all the OpenGL fifo is dispatched to the graphics card, so isn't not everything will have completed on the graphics card before it returns. glFinish() prior to the barrier will make sure that the all the OpenGL fifo is dispatched and the graphics cards has completed all operations before it returns so you can be sure that things are properly ready to swap. There is one gotcha with all these though - waiting for the OpenGL pipeline to be flushed and completed down on the graphics card adds a delay on the CPU that breaks the parallelism between the CPU and GPU so performance can be lower.

Re: [osg-users] Mac OSX Lion Installation
Hi, Am 14.01.12 23:31, schrieb Erick Bazan: I'm really really new to OSG, I need to use it for my Virtual Environments class. I have some experience with OpenGL in Mac with Xcode. I've been searching all over the internet how to install OpenSceneGraph in Mac OSX Lion and use it with Xcode (4). All I found was tutorials explaining how to install it from the 2.8 dmg and I tried installing the binaries to the Lion and Leopard SDK with no results. Anyone know how to install or compile OSG projects from scratch in Lion with Xcode, as I said, I'm new to the whole OSG. checkout/download the osg-source, download a recent cmake version, open it, select the osg-source-tree, select a build-directory, select the xcode-generator, make sure you set OSG_WINDOWING_SYSTEM to Cocoa CMAKE_INSTALL_PREFIX to your needs If you want embeddable frameworks, set OSG_COMPILE_FRAMEWORKS to 1 (otherwise you'll get dylibs) generate the xcode-project files, open them in xcode, compile the INSTALL-target, you should now find the frameworks/dylibs/plugins in your folder given to the CMAKE_INSTALL_PREFIX Probably the quicktime-plugin will not compile, there's a fix in osg-submission waiting for review.

Re: [osg-users] Play audio files
Hi, thank you for your reply, it has been very clear and it has solved all my doubts. I have downloaded and compiled osgAudio. Now I want to integrate it in my own OSG-based program. So, how can I just open an audio file and play it? I mean the simplest way, no need for complicated features right now. Something like: open(myAudio.wav); playAudio(); Of course I understand that it is not so easy, but you can get an idea of what I need at the moment.

I have read that SDL only allows one audio channel, so I think I have to start using something else. I want also to play other audio files (mp3, ogg, wav, whatever). So, which is the best option right now? I have read about osgAL and openAL. I dont know which one is better with the version I am using (OSG 3.0.1) or if there is a better solution to these two. Another thing to consider is that I would like to work with LGPL (or similar) licenses if possible. I think those libraries are LGPL, but as they depend on additional libraries I am not sure if I can use them as LGPL or not. As the creator of osgAudio, I can answer this. osgAudio is the literal and philosophical child of osgAL. We started osgAudio using the osgAL source, fixed a number of design and implementation issues, added compile-time selection of audio backend (openAL or FMOD) and polished it up. Thus, osgAudio. Even openAL's creator agrees that you should probably use osgAudio now, since it has newer fixes. OpenAL was LGPL, now proprietary (Creative Labs): http://en.wikipedia.org/wiki/OpenAL You'll have to interpret their licensing yourself. There is also OpenAL Soft: http://en.wikipedia.org/wiki/OpenAL#OpenAL_Soft OpenAL Soft is an LGPL-licensed, cross-platform, software implementation FMOD is proprietary but has a non-commercial license: http://en.wikipedia.org/wiki/FMOD FMOD is available under multiple license schemes: FMOD Non-Commercial License, which allows software not intended for commercial distribution to use FMOD for free. You could fairly easily add support for other backends to osgAudio if you wished, but I'm not aware of too many other 3d spatial audio toolkits. -- Chris 'Xenon' Hanson, omo sanza lettere. xe...@alphapixel.com http://www.alphapixel.com/ Digital Imaging.
