HI Cliff, This type of error comes from gcc now being tighter w.r.t inclusion of C style headers so that if you want access to the functions in these C headers you now need to explictly include them. It's not a bug in gcc, and not a bug in the OSG, it just one of those moving targets that we as

Hi Jose, Getting 10fps is pretty bad, I personally wouldn't be happy till get that up to 60Hz+. The first step is to work out what is the bottleneck - you say that you have too many triangles in your scene, and cutting this down gets you back your frame rate. There are lots of ways to manage

[osg-users] Shaders, osg::notify and IP

Hi all, My colleague was recently doing some debugging and found that when OSG_NOTIFY_LEVEL is INFO or higher all of the shader code comes out as debug. Luckily because of the way the osg::notify code is written we can prevent any slightly osg savvy 3rd party getting hold of my shaders by setting

Re: [osg-users] Shaders, osg::notify and IP

You should be aware that suppressing the debug output is by no means sufficient to protect your shader sources. Any decent OpenGL debugger library can protocol your shader sources from your running application. See http://www.gremedy.com/products.php as an example of an OpenGL debugger.

[osg-users] Passing explicitly loaded model to DatabasePager for expiry management

Hi Everyone, I have quick question. We have added simple ReadCallback to osg::IntersectionVisitor to enforce loading of highest PAgedLODs from our terrain. We simply call osgDB::readNodeFile( PageLOD_file ). Intersection works, but it looks like these files are not stored in any cache nor they

Re: [osg-users] Shaders, osg::notify and IP

Hi Colin, The initial value of NotifyLevel is set from the OSG_NOTIFY_LEVEL env var, which users can set themselves, but your application can set the value via: osg::setNotifyLevel(osg::ALWAYS); Which will make the OSG notification system always ignore all calls to osg::notify(..), this way

It seems that there isn't a good solution to prevent people seeing shader code then, I didn't think of the plugin thing. Even if OSG was made completely secure, it seems that you could get shader source code from OpenGL debuggers ( as Ralph Kern said earlier ). I guess it is just a matter of
