Abstract
In this paper, we propose a new type of deform map where both the close and the distant view are expressible. When we use a 2D ordinal map of a local area, we sometimes want to know some information of the outside, i.e. the direction of a far city or the shape of far mountains from the local area. To realize this demand, a new expression is proposed. The local information is drawn in the central area of the map by top view parallel projection like 2D ordinal maps. The information of the far cities and mountains are drawn in the surrounding area by overhead or side view projection so that the direction of cities and the shape of mountains are expressed. To establish smooth connection of both areas, a novel multi aspect projection technique is developed. Several rendering techniques, such as blending of multiple map textures, LOD control, and contour enhancement of mountains, are combined to obtain comprehensible result within interactive time.
