Re: [osg-users] [osgPlugins] OpenFlight plugin update

Hi, Here is a screenshot which shows the bump map capability we're interested in, but really what it does it let you set up a bunch of parameters and textures which can be sent to your shaders. This way you can do modern rendering effects from your FLTs: [Image:

Re: [osg-users] How to get all visible nodes

HI Artem, Just write a NodeVisitor that has it's traversal mode set to TRAVERSE_ALL_CHILDREN i.e. class FindAllNodes : public osg::NodeVisitor { public: FindAllNodes(): osg::NodeVisitor(osg::NodeVisitor::TRAVERSE_ALL_CHIILDREN) {} void apply(osg::Node& node) {

Re: [osg-users] OSG and NVX_gpu_memory_info

HI Garth, I'd use a RealizerOperation. Have a look at the osgvolume example to an example of using a RealizerOperation to get information from the graphics context. Robert. On 30 September 2015 at 03:49, Garth D wrote: > Hi all, > > I was wondering if anyone

Re: [osg-users] [osgPlugins] OpenFlight plugin update

Hi Chris, Hi, I've started writing an update to the OpenFlight plugin to support the "extended material" options in Creator, mainly so we can use the auto-generated bump-map textures in our shaders. I'm not familiar with this feature set of OpenFlight, maybe you can give a more detailed view

[osg-users] Threads leakage with late use of osgViewer::setThreadingModel()

Hello list, we are experiencing a situation on OSG 3.2.x on Linux where we are unable to create new instances of osgViewer because pthread_create() suddenly fails with ENOMEM. Our investigation showed that this was due to calling osgViewer::setThreadingModel(osgViewer::Viewer::SingleThreaded)

Hi all, > - An osg::Camera::DrawHandler... > - An osg::Node::NodeHandler... I just noticed some mistakes in my original post: DrawHandler should be DrawCallback, and NodeHandler should be NodeCallback. Sorry about that. I'm writing the emails on one machine and reading from another, and

Hi Just an update. I managed to make osgAndroidExampleGLES1 work based on the Android.mk settings for osgSimple and am able to load cessna.osg or any other osg models. However, i am still not able to make osgSimple work based on the predefined setting. If anyone is interested then I can provide

Re: [osg-users] OSG and NVX_gpu_memory_info

HI Garth, Sorry for the typo, the setRealizeOperation is what I was referring to. If you want to check periodically then just use a Camera::DrawCallback attached to the main camera attached to the GraphicsContext/Window of interest. This will be called every frame, but within this callback you

[osg-users] Avoiding texture release

Hi, I have a switch node with two geodes containing one geometry each, shallow-copied from the same geometry but with different state sets having different textures. The textures are large (8192x8192) and this causes a massive frame drop when switching between the two geodes at runtime. I know

Hi Fabrizio, For changes to the core OSG just send them along to the osg-submissions mailing list. The best way to post them are as whole modified files. I don't know what the current development status of osgOcean is so can't comment on the best way to progress with this. One route might be

Re: [osg-users] Avoiding texture release

Hi Andreas, I suspect just letting the OSG do it's thing with be just fine, and it's simply the amount of memory on the GPU that these textures take is fundamental problem you need to address. Try texture compression on the textures, or try a small pixel format. The other approach would be to

See the FAQ: http://www.openscenegraph.com/index.php/support/faq#HowdoIcaptureascreengrab If you want to record a video, just record the individual frames into files and then use ffmpeg utilities to combine these into a video. If you don't want to do that, use Google - there are plenty of

I just actually finished a work with ffmpeg and streaming videos from OSG rendering. You just capture the single images as Jan suggested - based on the osgscreencapture example, and then pass the captured osg::Image to ffmpeg - you dont have to do it frame by frame into file and use he offline
