Abstract:
A map display method, comprising:a surface generating step for generating surfaces which are obtained in a process of gradually deforming a surface from a first shape to a second shape, the generated surfaces including (a) intermediate surfaces that each have an intermediate shape between the first shape and the second shape and (b) a surface that has the second shape; a mapping step for (a) transforming first coordinate information to second coordinate information on each of the generated surfaces, the first coordinate information showing positions of objects in a map, and (b) mapping graphics that represent the objects onto each of the generated surfaces with reference to positions shown by the second coordinate information, to obtain mapped images corresponding to the generated surfaces; and a projecting/displaying step for perspective-projecting the mapped images sequentially onto a flat virtual screen to obtain projected images, and displaying the projected images in sequence.
