Hi folks, I have a camera responsible for updating some texture by rendering to it. What is the preferred way/callback to let the camera run only every 10th frame or so. I know I can use the the nodevisitor to get the framenumber, but I'm puzzled which callback to use to skip the camera all

Re: [osg-users] Help with callbacks and cameras

Hi Sebastian, I struggled with the same problem. The way how I resolved this was by keeping reference to the camera and working with the NodeMask (the camera was turned on at each N-th frame, otherwise was off). And the framebuffer was kept this way Hope this helps Nick On Tue, Dec 3, 2013 at

Re: [osg-users] Help with callbacks and cameras

Hi Sebastian, You could use an osg::Sequence node above the RTT osg::Camera that makes sure it's only traversed are certainly times, or use a custom cull callack attached to an osg::Group that decorates your RTT osg::Camera and decides whether to traverse or not to the interval you want. Robert.

Re: [osg-users] Help: issue about NaN detected by CullVisitor.

Hey, It has been fixed. I have forget to port the getScreenSettings function, once it been ported, the test program can running on the target. can you tell me how you solved the problem exactly? Thank you! Gickl[/quote] -- Read this topic online here:

[osg-users] help~, i used multi-threads loading function, but osg error..?

Hi, first i'm sorry for my english writing skill. i'm begginer ^^; :( :-* i try to 28 multi-threaded node loading test. total polygon is 5*10^6, vertices are 3*10^6. sometime, osgDB::readNodeFile has error like this, when the first running, 1. Warning: Could not find plugin to read objects

Re: [osg-users] help~, i used multi-threads loading function, but osg error..?

Hi Chang, This is probably due to a static initialization of the various proxy objects. OSG-3.2 has a few bug fixes related to initialization and might help, but in general I have to say the plugins aren't written to handle multi-threaded initialization. Once they are initialized it should be

Re: [osg-users] Help regarding osgcluster

We tested on a better more secluded LAN and the results were pretty good. The ping time from the master to the slave is around 0.5ms. However i'm still not able to figure out the -o and -f settings to setup the camera across different displays. Some help with that shall be highly appreciated.

Re: [osg-users] Help regarding osgcluster

arguments.getApplicationUsage()-addCommandLineOption(-f float,Field of view of camera); arguments.getApplicationUsage()-addCommandLineOption(-o float,Offset angle of camera); -f is Field of View, pretty standard. -o is offset angle, which allows you to have each slave display a different

Hi, We are working on developing a distributed rendering system for a 3*2 tiled display. We have been trying to setup osgcluster and use it for the same. Though it works out well for a two-tiled screen, i am able to understand the '-o' and '-f' parameters using which i think we have to setup

I guess I'd need a specific question to answer. Optimize what? On Thu, Jun 20, 2013 at 3:17 PM, Rishabh Raj rishabhr...@gmail.com wrote: Hi, We are working on developing a distributed rendering system for a 3*2 tiled display. We have been trying to setup osgcluster and use it for the

Re: [osg-users] Help regarding osgcluster

Optimize the amount of data that flows, from the master to the slaves? We were working on a small model, even then there was visible lag in the two-tiled display connected via the intranet. I would like to correct a major typo in the mail which i realised just now. 'I am not able to understand

Re: [osg-users] Help regarding osgcluster

The amount of data flow is very very small. It's a one packet per frame update of the camera modelview matrix and such, necessary to keep the slaves in sync. The internet has lag. Even over a local area ethernet there will be a certain amount of lag. What is your ping time from the master to the

Re: [osg-users] help me with my first osg program ...

Hi Omprakash, Clearly it's a missing include, which might be down to an error in your CmakeLists.txt file in which case having a look at CMake docs might help you on your way. Or it could be simply that Cmake isn't finding the OSG as you haven't installed it in a place it can find or that you
