[0064] Refer below Figure 1 to Figure 7 The image generating apparatus of the first embodiment will be described.
[0065] First, refer to figure 1 The basic configuration of the image generating apparatus of this embodiment is described.
[0066] exist figure 1Among them, the image generating device 1 is composed of a drawing application program processor 11, a graphics library 12 and a drawing device 13, wherein coordinate transformation information 14 such as visible points, visible ranges, light sources, etc., and information such as roads, buildings, and maps, etc. The drawing object information 15 is input into the image application processor 11. As will be described in detail below, the graphics library 12 and the drawing device 13 are combined into a system unit, which can be optionally replaced as a unit corresponding to the drawing application processor 11. This facilitates an improvement in replacement ability, which is a unique feature of the present invention...
