Abstract: Systems that will allow users to navigate and explore a rendered world, at a range of screen size to world size ratios, including a system by which each scene that presents a portion of the rendered world is, unlike prior art, optimized for immediate game play, interpretation and/or interaction and for user awareness of context given the user's chosen screen size and zoom level, a system to help users to navigate more effectively when the screen size to world size ratio is so low that navigation becomes difficult and systems to provide both context and visual access even when the screen size to world size ratio is so low that only one, or even just a portion of one, item can be displayed visually.
