Re: [osg-users] [build] Install problem with OSG 2.8.3
yeah, I misread the version number, but I'm pretty sure its a problem with VS2010. When VS2010 builds the solution, the binaries are placed in bin/release directory... however when I use VS2008, the binaries are placed directly in the bin directory, thus the install script not having any problems. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=26925#26925 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

when it is actually located at :

I also had the same problem with OpenThreads.dll, and I changed the
cmake_install.cmake in that directory to the correct paths by removing
"../../bin/"
why is this happening in the first place?

[osg-users] OSG + SDL
Hi, I'm trying to use OSG to draw to a SDL window. I've found lots of information everywhere on this, but it all seems to use SceneView, which is said to be deprecated, and doesn't work when I try it. It's a shame because it's exactly what I needed to integrate nicely with my code. I heard there's another way to do this, using the osgViewer, but I never found a sensible piece of code that would explain me what to use and how it works. I would rather use my own code to do this rather than a library, as I need a good control over input and over the SDL event queue. The best would be a way to draw a scene to the current openGL context, using only opengl commands. What would be the correct way to do this ? Thank you for any information regarding this.

Re: [osg-users] Detecting new data merged into the scenegraph by the DatabasePager
Hi Chris, When I implemented the rendering on demand feature in osgViewer I added a convenience method ViewerBase::checkNeedToDoFrame() to find out whether anything had changed in the scene graph. Have a look at the implementation in src/osgViewer/Viewer.cpp, Viewer::checkNeedToDoFrame(), among other checks it contains the lines: // If the database pager is going to update the scene the render flag is // set so that the updates show up if(getDatabasePager()->requiresUpdateSceneGraph() || getDatabasePager()->getRequestsInProgress()) return true; Robert.

Re: [osg-users] How to force FFMPEG plugin
Hi Mike, Another method above Mourad's tip is to append a ".ffmpeg" to the end of the filename, the ffmpeg plugin will automatically strip this and then load the video. It's my plan to make the ffmpeg plugin the default video plugin for the OSG, but we'll need to sort out a good default audio implementation first, as both the xine and quicktime plugins provide audio for video's, something that ffmpeg itself doesn't provide.

I haven't heard of users actively using OSG on Windows modile systems yet, you may well be the first. What problems are you seeing? One thing you could do to as a test is to build the OSG against OpenGL ES 1.1 on the desktop or even just normal OpenGL but with the OSG built against the subset of OpenGL that OpenGL ES 1.1 has, and get your app working well on the desktop then test it against the mobile target.
