That looks fantastic. Any chance of another mock-up based on a real tactical display, with several planets, ships, and weapons? Add a background of stars? Things to worry about when scaling up ... - reach of mouse ... the galaxy coordinate offset traversed by the mouse in a 1000x1000 tactical will be half of the standard 500x500 client display, so it will have a very different feel unless people want some special mouse acceleration mode, - smoothness of rotation ... the server keeps angle of rotation for ships as a number from 0 to 255, which is 1.4 degrees per bit ... clients have kept only certain rotations of the image, such as 16 of them, which is one every 22.5 degrees ... at higher resolution this rotation is more chunky, but then the update rate of ten per second and the orbital velocity may combine to change this yet again. -- James Cameron mailto:quozl at us.netrek.org http://quozl.netrek.org/
