Problems solved by technology

The problem is high-speed executable and replaceability, because the drawing method used relies on a unique drawing device
Therefore, in the case of introducing a new drawing device into the system, it is necessary to change a preparation device for image information data input to the drawing device, which makes it impossible to efficiently perform device preparation only by replacing the drawing device
That is, since coordinate transformations, which are an important part of drawing, function as state machines containing states, replacement of a single function to reduce device dependencies, as seen in the standard library, is not sufficient in drawing Compensate for drawing device performance in

Abstract

A picture generating apparatus (1) is provided with: a drawing application processor (11) for instructing a drawing device (13) to generate a 3D image; and a graphics library (12). The drawing application processor is provided with a drawing object information generation device for generating drawing object information to generate an image; and a coordinate transformation information generation device for generating coordinate transformation information. The drawing device generates the 3D image by applying the coordinate transformation information to the drawing object information. Consequently, this ensures the high-speed generation of the image and the ability of replacement of the drawing device.

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...
