Problems solved by technology

This technology is a simple technology for displaying 3D images, but no matter how much the frame buffer capacity is increased, this solution of using a larger frame buffer is not enough to solve the problem of display area movement, which is Because the image information stored in the larger frame buffer is insufficient to cover the display area that changes with changes in the visual point that typically changes in the 3D image

Abstract

An image generating apparatus (1) is provided with a drawing application processor (11) and a graphics library (12) that allow a drawing device (13) to generate a three-dimensional image. The drawing application processor (11) generates coordinate transformation information and drawing object information, which are divided from data to generate an image, with respective information generating device. The graphics library (12) stores and manages these coordinate transformation information and drawing object information. The drawing device generates a 3D image on the basis of these stored and managed data, and then outputs the generated 3D image to a display device. The drawing object information is generated relative to an area bigger than a visual range corresponding to the 3D image to be generated at the present.

Description

technical field [0001] The present invention relates to an image generating device and method for generating a three-dimensional (3D) image based on three-dimensional coordinate information, and to an electronic device such as a navigation system incorporating the image generating device, and a computer program. Background technique [0002] Recently, R&D (research and development) on electronic controllers that control the movement of cars, and the spread of navigation systems that assist car driving are noteworthy. The navigation system has a basic configuration including various databases for displaying map information, current position information, various guide information, etc. on a display unit. Furthermore, the navigation system typically also finds driving directions based on the entered criteria. It is also designed to display a found driving route and a current location based on GPS (Global Positioning System) measurements or autonomously measured on a map, and i...
