Ok :-) .. I will answer it too . I am working with older version of osg where the Geometry was still not inherited from Node so I had to apply a special case for Geodes ... Sorry for the noise ;-) Cheers! Nick On Fri, Aug 26, 2016 at 5:58 PM, Trajce Nikolov NICK <

[osg-users] Collect all the osg::Materials from a osg::Node using osg::NodeVisitor

Hi Community, this is really simple, but for a reason it is not working on my end. I have simple model with animation (a cube that scales over time). On load I launch a NodeVisitor to collect all the Materials. I can see one Material in the text file but the parser is not hitng it. Here is my

Re: [osg-users] Encrypted 3D Models

It doesn't look like the OSG zip plugin supports a password option, but it wouldn't be too hard to extend it to support password-protected zipfiles. Which could themselves be in memory. On Fri, Aug 26, 2016 at 7:25 AM, John Farrier wrote: > Perfect. Appreciate the help,

Re: [osg-users] PagedLOD glitches

Yeah, something's not right with your scene graph. You shouldn't see that behavior if your PagedLODs are structured correctly. You might add some debugging messages to determine what is happening in the PagedLOD node that contains the geometry that disappears in #2, as it must be switching to

Re: [osg-users] PagedLOD glitches

Hi Andreas, The PagedLOD is designed to only switch to a higher level of detail once that level of detail is merged, it'll fallback automatically to next highest level of detail automatically until this happens. This "should" mean that you never get gaps where neither LOD is available. I've

Re: [osg-users] PagedLOD glitches

Hi Robert, The glitches are purely visual. I have no overlapping ranges, my problem is the opposite - when I'm moving towards a level and the range switches, it takes a while to load the high level and the low level is switched off. While loading, there is just empty space for a while until

Re: [osg-users] Encrypted 3D Models

Hi John, To read from memory, you can get the plugin you want by calling osgDB::Registry::getReaderWriterForExtension(...) or osgDB::Registry::getReaderWriterForMimeType(...) and then call the stream version of readNode: ReaderWriter::readNode(std::istream& in, ...); Glenn Waldron -

[osg-users] Encrypted 3D Models

Hi, I have a set of 3D models i would like to distribute, but their license is restrictive and I must provide a way to protect the IP. The best way to do this, I think, is to use a format that encrypts the models on disk and decrypts them when I read them into memory. Is there any support

[osg-users] PagedLOD glitches

Hi, Is there any way to avoid glitches in the PagedLOD during loading of the higher level after the lower level has switched out? When flying over my quad-tree terrain the tiles are flickering and the background color is visible a short while before the higher level has been loaded. One can
