Re: [osg-users] New osgTerrain serializer not calling TileLoadedCallback

Hi Brad, A solution for serialziers to call static functions at the end of reading/writing is to use a user serializer. The serialziers/osgManipulator/Draggers.cpp uses a DefaultGeometry serializer to run setupDefaultGeometry() once the reading process is finished, and this can also be applied to

Re: [osg-users] Shader composition, OpenGL modes and custom modes

Hi Wojtek, I don't really see a strong separation between emulation of the fixed function pipeline and shader composition. My current view is that we'll have StateAttribute's that provide batches of uniforms, any shaders that are required, and guidance on how into inject support for them into

Re: [osg-users] cross axes

Another question. Now the axes works fine in the left bottom corner but if I resize the viewer window (I use QT embedding the viewer inside) the cross axes object is deformed accordingly. How can I prevent that? I mean, I agree to resize the axes but in a homogeneous way for every axis.

[osg-users] viewer with ortho-graphic projection

Hello everybody, Is there something in osg that can manipulate(zoom/pan/rotate) an orthographically projected view? like trackBallManipulator does for a perspective projection.. Sunil. ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] New problem with VPB serializer

Hi, I just looked over last night's email and realized what I wrote is about as clear as mud. The problem is this: when the build options are read from disk by the readOptionalLayerSet method in BuildOptionsIO a leading empty string is retrieved from the stream resulting in an optional layer

Re: [osg-users] Shader composition, OpenGL modes and custom modes

Hi, as I mentioned somewhere else, we are also thinking about a shader composition concept. After some consideration we came to the conclusion, that shader linking is probably the most time-effective approach. So we would go with Wojtek and use his VirtualProgram - extending and implementing

[osg-users] Collada loader crashing

Hello, I've found a reliable crash in my application which seems to be caused by the collada loader. It seems like the collada loader can only be called in one thread. Attempting to load a model in second thread will immediately crash my application. I looked into this and it seems to be a

[osg-users] DrawCallBack Screeshot problem

Hi, I am actually trying to find another way to create a screenshot since using the osgscreencapture (pbuffer) doesnt work properly. I tried to do a simple DrawCallBack where I will call readPixels and write the image on the disk, the viewer is setupInWindo of the size 1024x1024 , and so the
