Steam drive is making slow but steady progress. At the moment I am making a small multi-format model viewer as a tool for the main engine. This tool is allowing me to write all the basic engine routines like the console, model loading etc. in a small easy program. This will make it easier to write aspects of the engine without getting bogged down in the rest of the code. Its just my way of learning...start small.
The model viewer is coming along well. I'm currently writing the logic for the console.
