[osg-users] osgDB/Reentrant Mutex not threadsafe ?

Hi all, I am not quite sure if osgDB/Reentrant Mutex is threadsafe (just got into Multithreading). Lets make a little example. Consider two Threads: Thread one and Thread two. Now lets make this sequence of operations: * Normal Program Flow everything runs fine so far. * Thread one just unlocked

Hi SInisa,I don't really haven any ideas to what might be amiss. It could be a bug, or it could be a build problem of some kind.Could you modifying one of the examples to do the deep copy in the way you are using it to recreate the problem. Once I have code that reproduces the problem I and others

Re: [osg-users] Re: problem with 1.2 and openflight models on mac (fixed, kinda)

Hi James,The library name should be osgdb_OpenFlight to be consitent with all other platforms. The old plugin should be called osgdb_flt, this should allow users to try both plugins without having to rebuild. I believe this problem with have existed in 1.1 too, as this is when the new OpenFlight

Hi Paul,First up, just try to get multi-texturing working without shaders. The techniques I suggest are pretty advanced so rather than go the whole way in one leap try standard multu-texturing. To apply a detail texture over the whole terrain you don't need to get hold of any vertices, you can

Hi Andrew,Under 64 bit linux I'm getting 1.4 Gb used for all plugins and examples, and 1.2 is bigger than 1.0... So it would seem VS is pretty hungry. The Win32 binaries aren't so bad, in order of 20Mb for everything. One solution for you is to not build everything. VS isn't very good to selecting

AW: [osg-users] osgDB/Reentrant Mutex not threadsafe ?

Re: [osg-users] osgDB/Reentrant Mutex not threadsafe ?

Hi Richard,Thanks for the futher explanation, very subtle, but yes this looks like a potential bug so very well spotted.I believe it is a very unlikely problem to arise in action due the the fact that in lock() _threadHoldingMutex is set first, then _lockCount is set to 1, which will probably

Re: [osg-users] Texture Atlas

Hi Julia,The texture altas builder can only merge textures that don't repeat, and are of the same pixel and data type. If you write out to .ive the texture atlas imagery will be written out, and if you write out to .osg you should be able to notice the texture atlas by image file name. The .osg

Robert I noticed when running the osglightpoint example I was getting a step change in performance as I move towards the light points. It goes from about 200Hz immediately down to about 3Hz. Looking at the stats display its the draw that's taking the time. The issue goes away when I change

Re: [osg-users] LightPointNode performance

Hi Colin,This shouts driver problem to me. On NVidia when I zoom in the GPU stats (new to 1.2) as well as the cull and draw all stay very low, basically the cost is pretty near constant. There is a slightly higher fill requirement when you zoom in but its still very light on fill demand. Robert.On

Re: [osg-users] Is OSG threadsafe yet?

No, let's talk about the details here. OpenSG, like other scene graphs of the past, uses a multi-bufferred approach to effect thread safety. OpenSceneGraph has avoided this route for the multiple disadvantages of a multi-buffered system. A multi-buffered system requires that there be a buffer for

after compile, copy dlls and libs to another place and add the path to Visual Studio for additional library and binary paths. Then you could go ahead to Batch build - clean to delete any temp files. It is not necessary to keep *.obj, *.pdb files on your hard disk. In case you want to keep example

RE: [osg-users] Cg support with OSg

I second that question. We've had great results with OSG 1.0 and osgNV, but the website stops at 10th September 2004, so I'm not sure osgNV is an active project anymore. I think CgFx support would be a nice addition, plus better array parameter support. I'd like to upgrade to 1.2 but can't go

That looks like you have a null pointer somewhere. Looking at the line of code, I'd imagine getEventQueue() is returning null, so that'd be the first thing I'd look at. John Donovan Sony Computer Entertainment Europe http://www.scee.com [EMAIL PROTECTED] wrote on 15/09/2006 16:52:41: Hi,

Hi,The osgGA::EventQueue is used in osgProducer, and its usage is fully multi-threaded, and appears pretty robust in this environment. I would be very suprised is there is an actual problem with ScopedLock too as its used all over the OSG and has yet to cause any problems. This is not to say

Thanks for the responses. Firstly, I have disabled all of my own GPU shader code. This didn't cause any change in the error. The scene consists simply of a single object and a single terrain database. Removing the terrain database does get rid of the problem, but that also doesn't seem to help
