Re: [osg-users] How to delete a NodeCallback*?

Hi Lv, You will never need to manually delete your node callback object, because it is manged by ref_ptr when added with setUpdateCallback(). It will be automatically released when no nodes referencing it (that is why your application crashes when you explicitly deleted it again, which is already

Re: [osg-users] OT: VS2010 LNK2005 problem related to ostringstream

I don't think MS considers this to be a problem. It is by design. Not being able to derive from ANY stl classes is quite serious if you ask me. Fiddling around with allowing multiple symbols and other hacks does not really present it self as a stable and viable solution. I managed to get around

Re: [osg-users] setUpdateCallback fails under slave-camera

Hi Timm, I ran into a similar problem to what you have and solved it without having to modify the OSG Core source code. The problem is that osgViewer does not do eventTraversal and updateTraversal on the slave's subgraph regardless if they are using the mastersSceneData or not. I'm submitting a

Re: [osg-users] hiding objects from a cloned scenegraph hides the original...

Hi Ted, A shallow copy will share as much as possible of the data below the object you are calling clone on. Only a deep copy will force the data itself to be copied. As a general note, you want to avoid duplicating data as much as possible, so share as much as possible. In you case it might

Hi Simon, OpenGL doesn't allow you to change state in the middle of rendering a primitive, let alone per vertex. The only way to change material per vertex would be to have a single vertex per osg::Geometry, but this isn't going to work if you want you vertices to be meshed in anyway... What it
