The idea is to write a minecraft map renderer (along the lines of Cartographer and the like), and output tiled images which would then be fed into google maps or OpenLayers to get a nice high-res, explorable map.
Similar to the second example, it'd be for an offline render on a headless server (which may or may not have a proper graphics card, hence wanting a software renderer). So speed isn't an issue, but I think without a proper ortho view transform the map tiles aren't going to join up correctly.
Since I don't care about speed, is there some way to hack it? The Camera seems to basically just be a matrix, can I construct an ortho matrix manually and force the camera to use that somehow? Obviously things like Camera.lookAt would cease to work, but it'd be a heck of a lot easier than writing my own software renderer.
