This examples is rewritten as a more comprehensive example of Far and Osd APIs to generate batched index buffer and vertex buffer, as well as sharing same topology and stencil table among multiple objects. Also this change includes an experimental code path of using glMultiDrawElementsIndirect. It's currently incomplete due to the missing interface of osd tessellation shader.
