00031  * The init data manages static, per-instance application data. In this example,
00032  * it holds the model file name, and manages the instantiation of the frame
00033  * data. The frame data is instantiated seperately for each (pipe) thread, so
00034  * that multiple pipe threads on a node can render different frames
00035  * concurrently.
