Image generating apparatus, image generating method, and computer program
First Claim
1. An image generating apparatus for drawing a three-dimensional image comprising:
- a drawing object information generating device for generating drawing object information, which is information for drawing objects as the three-dimensional image, in a single coordinate system;
a coordinate transformation information generating device for generating coordinate transformation information, which is information for defining a view point, a field of view, or both of the view point and the field of view concerning the three-dimensional image, separately and independently from the drawing object information;
a drawing object information storing device for storing the drawing object information, separately and independently from the coordinate transformation information;
a coordinate transformation information storing device for storing the coordinate transformation information, separately and independently from the drawing object information; and
a drawing device for carrying out an image generating process of generating the three-dimensional image by using the drawing object information that is directly input from said drawing object information storing device to said drawing device and the coordinate transformation information that is directly input from said coordinate transformation information storing device to said drawing device, and for supplying the three-dimensional image to a display device,wherein the drawing object information generating device generates, in advance, not only the drawing object information corresponding to the objects to be displayed in the image generating process that carries out now but also the drawing object information corresponding to other objects that expected to be displayed in the image generating process that carries out at a different time, the drawing object information storing device stores the generated drawing object information corresponding to the other objects, and the drawing device generates the three-dimensional image corresponding to said other objects by using the drawing object information corresponding to said other objects stored in advance, andwherein the drawing object information and the coordinate transformation information are separately and independently generated, stored, and managed before the generation of the three-dimensional image by said drawing device.

Abstract
An image generating apparatus (1) is provided with: a drawing application processor (11) for indicating a drawing device (13) to generate a 3D image; and a graphics library (12). The drawing application processor separates information to generate the image into coordinate transformation information and drawing object information and generates both with two independent generating devices respectively, and the graphics library stores and manages these information. The drawing device generates the 3D image on the basis of these stored and managed information and outputs it to a display device. The drawing object information is prepared for a broader area than the area of a field of view corresponding to the 3D image to be displayed this time.
