 * The init data manages static, per-instance application data. In this example,
 * it holds the model file name, and manages the instantiation of the frame
 * data. The frame data is instantiated seperately for each (pipe) thread, so
 * that multiple pipe threads on a node can render different frames
 * concurrently.
