Hello Manfred,

Actually I didn't generate any class, I just copied the OSGDVRSimpleShader files nad modified there names. That's not really nice but I don't konw how I should do. Just for information: I'm working with Windows XP and Visual Studio 7 .Net 2003 ... Well, I tried to do like the Cubes example, but I got following the compile error:

OSGDVRRGBShaderBase.cpp(16) : error C2491: 'osg::DVRRGBShaderBase::MTInfluenceMask' : definition of dllimport static data member not allowed

I hope you can help me....

Vincent

Hello Vincent,

I didn't find an example in order to inherit from an OpenSG class. I seems to be not so easy. Do you have an example ? Should I do exactly the same way like OSGDVRSimpleShader ? I tried it but had some runtime problems...

You did use fcdEdit for generating the class, right?
I know there are some tricks for external OpenSG classes to work. But I have to hand over problems with building OpenSG and OpenSG based
applications to someone in the core team.

What I usually do is enter "My" as name of the library for the 'external'
OpenSG classes. There used to be a template OSGMyDef.h in Examples/Cubes
which I just copied into the directory of the new node. After that it just
worked. But I am not shure whether this file is still maintained.

I haven't updated my OpenSG packacke for quite a while.

        Manfred.
