2. Description of the Related Art A three-dimensional shape CG image (three-dimensional shape model: wire frame model) is a model image created to express a three-dimensional CG image, and includes two or more images viewed from different directions (angles). It is composed of a dimensional shape CG image model.

The three-dimensional CG image is subjected to rendering processing (pixel generation) for each of the two-dimensional shape CG image models viewed from a plurality of different directions (angles) of the above-mentioned three-dimensional shape CG image to remove hidden surfaces. , Texture, lighting, and coloring (shading).

When the three-dimensional CG image is represented as a three-dimensional CG image, the two-dimensional shape CG is used.
It is created by performing rendering processing (pixel generation) on each image model and performing texture, lighting, coloring, and the like.

The three-dimensional CG image is displayed by rotating or moving a plurality of two-dimensional images viewed from different directions (angles) on a computer output display screen (monitor) in order. It is represented as a virtual three-dimensional CG image (including virtual reality).

[0006] In recent years, a business model has been put into practice in which a two-dimensional image obtained by printing a catalog printed matter or a publication is printed on a sheet by a desktop publishing (DTP) method. The three-dimensional shape CG of the two-dimensional image such as printed matter or publication
An image or a three-dimensional CG image generated by rendering a three-dimensional shape CG image to generate pixels is used as conversion source data (original data: original data), and an image image of texture, lighting, coloring, etc. is appropriately added to the data. An increasing number of businesses are changing or modifying to duplicate desired two-dimensional images.

[0007]

By the way, in the case of producing a high-definition two-dimensional image by printing the above three-dimensional CG image as a conversion source data (original data: original data) on a sheet, the conversion to be used. The original data is
High-density 3D CG with high-density wire frame
It is desirable to use an image (or its image data) or a high-density three-dimensional CG image (or its image data) in which three-dimensional CG image data having a high density is rendered to generate three-dimensional CG pixels.

However, in such a case, the high-density three-dimensional shape CG image data (wireframe model data) or the high-density three-dimensional CG image data is used as the original data, and the observation angle is selected and designated for the image data. Then, for the high-density two-dimensional shape CG image data or the high-density two-dimensional CG image data observed from the specified angle, the desired high-definition two-dimensional CG
It is necessary to perform high-definition rendering processing by appropriately changing and correcting the image image such as texture, lighting, and coloring so as to obtain an image.

However, the high-density three-dimensional shape CG image data which is the conversion source data, the data relating to the high-density three-dimensional CG image data, or the high-density two-dimensional shape CG image data and the high-density two-dimensional CG image obtained from these data. Data related to data is stored in a data storage medium as two-dimensional frame image data, or in order to read it and perform high-definition data processing such as high-definition rendering, the data file capacity to the storage medium becomes large,
Moreover, the amount of data to be processed becomes enormous, which causes a decrease in data processing speed.

In addition, data processing using the high-density three-dimensional shape CG image data and the high-density two-dimensional shape CG image data, or high-definition rendering processing for the high-density two-dimensional shape CG image data is performed by a personal computer. When a desktop publishing (DTP) method is performed by using a computer or the like, there is a problem that a load on a personal computer or the like is heavy and it takes time to process or read data on the personal computer.

An object of the present invention is to generate a high-definition two-dimensional CG image for printing from a high-density or low-density three-dimensional shape CG image (or a high-density or low-density three-dimensional CG image) formed in advance. When creating, avoiding enormous amount of data and lowering of data processing speed due to high-density data processing, data processing of 3D CG image data by desktop publishing (DTP) method, data reading and reading, etc. It is to be able to process data quickly.

High-definition texture, lighting, and coloring for a two-dimensional shape CG image for creating a high-definition two-dimensional CG image for printing corresponding to the simple rendering parameters used for creating the two-dimensional CG image based on a table High-definition rendering for high-definition rendering processing such as And the stage to get a grayed parameters,
(8) Based on the obtained high-definition rendering parameters, a rendering program is operated to perform high-definition rendering processing on the two-dimensional shape CG image, and for printing with high-definition texture, lighting, coloring, etc. A two-dimensional CG image creating system comprising: a step of creating a high-definition two-dimensional CG image and outputting and displaying it.
