I have successfully created a char* data-field for the Horde3D::Geometry which
even successfully loads in
Horde3D::loadResource(generatedGeometryRes, cp, geomSize);

What would be the correct order to set a material and get this geometry into the scenegraph?
It think it might be a naming-problen (maybe not all nodes should be called "spec"...) or
a mistake in my scenegraph hierarchy.
Code:
        .......
        GeometryStreamGenerator* gsg = new GeometryStreamGenerator();
   const char* cp = gsg->getStream();
   specRes = Horde3D::addResource(ResourceTypes::Geometry, "spec", 0);
   Horde3D::loadResource(specRes, cp, gsg->getStreamSize());
   specNode = Horde3D::addModelNode(RootNode, "spec", specRes);
   specMesh = Horde3D::addMeshNode(specNode, "spec", stonesRes, 0, gsg->getNumTriangleIndices(), 0, (gsg->getNumVertices()-1));
   Horde3D::addNodes(RootNode, specNode);
   Horde3D::addNodes(specNode, specMesh);
        ....

Did you check the engine log? Maybe there are some hints what can be wrong.

After removing the two "addNodes(...)"-lines there are no error messages in the EngineLog.html
but my geometry still won't be drawn...
Code:
..........
0.265    Adding Camera node 'Camera'
0.265    Adding nodes from SceneGraph resource 'cube.scene.xml'
0.500    Adding Geometry resource 'specGeom'
0.500    Loading resource 'specGeom'
0.500    Adding Model node 'specNode'
0.500    Adding Mesh node 'specMesh'
0.500    Adding Light node 'Light1'

Maybe you cut off the messages, but I'm missing a log message about loading the shader and material. Are those present?

edit:
Is it possible that my static scenegraph "cube.scene.xml" (which is displayed properly)
somehow interferes with my dynamically generated geometry?

No that shouldn't make any difference. The engine does not know which of those resources are generated "dynamically" and which are loaded from a file.
Are you sure, that your dynamically generated data is correct? Did you tried rendering in debug mode?

My geometry data seems to be ok as it is visible in Debug-mode but not in wireframe view.

Solved!
After setting the appropriate material it works.
Thanks.
