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 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 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
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.
