Up: camera up Down: camera down Left: move in Right: move out W: Zoom out S: Zoom in Mouse: spin This is to test out my simplified rotation matrix I'm working on for a 3d tank game. (It'll be more like the 16bit mario kart, when that's done.) I'm new to 3d math and programing. I'm open to critiques! It's running on MITscratcher's fast pen drawer: "3-D figure simulation" Thanks! A challenge: make this into a 3d modeler. Allow the user to click and drag vertices, (the dots) (convert camera space back into the object's local coordinates.) or an easier way, allow the user to select a vertex, then use keys to move it. I'll look forward to see what you do with it.
