Re: [osg-users] Animation of shared model

Hi, Thilo. I believe you can achieve this by creating new top-nodes of animated model (nodes which contain animation manager callback), sharing model itself, and attaching new animation managers to them (sharing existing animations). Cheers, Sergey. 16.08.2012, 01:01, Thilo Weigel

Re: [osg-users] OSG application onMicrosoft Surfface table?

Hi Helen, I've seen some applications using WPF for their GUI and rendering OSG into a widget. Essentially you can embed OSG into a widget given its HWND. I don't remember the details so you may have to look around and do some testing on your own. On the other hand, if this tech really

Re: [osg-users] MatrixTransform behaving strangely on OSX 1.8 with XCode 4.4

I think I found the issue. There were a few previous posts that I thought were unrelated to what I was doing since they referred to using gcc, and I use clang. However, on closer inspection, it turns out gcc was the default during the make process (as a side note, I would think most people who

Hi, I'm trying to create a camera at a fixed location that can be rotated using a manipulator. From what I've read, it looks like a trackball manipulator might be the way to do this. The only problem is that when I set it up, in order to keep the camera at the fixed location, the eye and

[osg-users] Force remove pagedLOD

Hi, I use PagedLOD to manage the display of large amount of data. To avoid an overload of GPU memory, I would like to force OSG to remove these pagedLOD when inactives. I know the setTargetMaximumNumberOfPageLOD enable to disactivate the use of pagedLOD in cache for all application. But what I

Hi, I am trying to run some of my c++ code in OpenSUSE 12.1 using OSG. I installed the RPMs and should be good to go with OSG on that end. When I build my project though, all I do is #include osgDB/FileUtils and my compiler (gcc 4.6.2) crashes inside FileUtils saying expected identifier

How do I get OSG to re-create all GL objects in response to the GL context being recreated? I'm trying to get my Android GLES2 app to gracefully handle switching to/from the Activity where OSG is running, as well as to handle sleep/wake. Whenever these happen, the EGL context is lost, and all
