摘要 |
A drawing processing apparatus and method wherein scrolling display which provides no sense of incongruity is achieved in 3D display. 3D information is produced using information in a drawing object range extracted as a predetermined range on map data. The drawing object range of an object of the 3D drawing process is moved in response to a scrolling operation. While the drawing object range is moved, 3D image data are successively produced using the drawing object range at every point of time and outputted to implement 3D display on a display screen. Thereupon, the drawing object range to be used for the 3D drawing is moved such that individual portions in the drawing object range are moved by movement amounts determined with reference to a distance in a perpendicular direction at a reference position in the drawing object range.
