Basically yes. My problem is that I don't really get how the tesselation works and how to create new polygons using the geometry modified by the tessellation. I thought that the tesselation would simply add new PrimitiveSet such as DrawArrays and that I could have created my new polygons using the getFirst() and getCount() function of DrawArrays with my vertexArray. Unfortunately, when I look at my geometry after the tesselation, it only has DrawElementsUByte, and I don't see how I could get a list of triangles from this PrimitiveSet. I've looked at the DOC, the headers and the source but I don't see what to do.
Note that DrawElementsUByte essentially is-a std::vector<GLubyte> which stores indices into the vertex attribute arrays. Traverse the vector to get the indices, then look up the specific vertex position, normal, etc, in the appropriate vertex attribute array.
