Abstract

PURPOSE:To save file capacity and efficient processing by storing both or one of equation data and face data as to one graphic and managing the result in matching with the data kind and the purpose of application into a 3-dimension graphic data file. CONSTITUTION:The 3-dimension graphic data is registered by a registration section 1. In this case, the name of graphic, an index and the 3-dimension graphic data equation data are designated. The index commands one of the following three kinds. That is, index=1 stores the equation data and face data, index=2 stores only an equation data and index=3 stores only a face data. The designated graphic name, index and 3-dimension graphic data are registered in the 3-dimension data file 10 through a file control section 2, which manages the graphic name and the location of data (pointer) in a file correspondingly.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a file storage method for three-dimensional graphic data;
A file storage method that can particularly reduce the number of files or file capacity (conventional technology) Conventionally, this type of 3D figure data file has either formula data or surface data for one figure. , or always stored both formula data and surface data.

(Problems to be Solved by the Invention) The conventional three-dimensional figure data file described above either stores only surface data or formula data for one figure, or always stores both surface data and formula data. was configured to do so. Therefore, in the former case, it is necessary to refer to a separate data file for each purpose of use, which has the disadvantage of increasing the number of files, while in the latter case, there may be data that may not be referenced depending on the purpose of use. This has the disadvantage that the file size increases because it needs to be stored.

An object of the present invention is to store either formula data or surface data, or both of the above, in a three-dimensional figure data file in order to form a single three-dimensional figure according to the purpose of use and type of data. The three-dimensional figure data is structured in such a way that the above drawbacks are removed by selecting data from the three-dimensional figure data files according to the purpose, and the number or capacity of figure data files can be reduced in three-dimensional figure processing. The purpose is to provide a file storage method.

(Means for Solving the Problems) A three-dimensional graphic data file storage system according to the present invention is configured to include three-dimensional graphic data file means, selection and extraction means, and file control means.

The three-dimensional figure data file means is for storing both surface data and formula data, or one of them, depending on the type of three-dimensional figure data or the purpose of use.

The selection and extraction means is for selecting and displaying data that matches the purpose of use of the three-dimensional graphic data.

The file control means is for controlling the above storage, selection, and display.

(Example) Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment for realizing a three-dimensional graphic data file according to the present invention.

In FIG. 1, l is a registration section, 2 is a file control section, and 3 is a registration section.
4 is the extraction section, 4 is the selection section, 5 is the display section, 61 and 62 are the displays, 7 to 9 are the data areas, l
O is a three-dimensional data file.

The present invention consists of a registration section 1, a file control section 2, an extraction section 3, and a selection section 4. First, υ three-dimensional figure data is registered in the registration unit 1'. At this time, the figure name, index, and three-dimensional figure data (formula data) are specified. Here, the index indicates one of the following three types.

That is, index=1 is for storing formula data and surface data υ, index=2 is for storing only formula data, and index=8 is for storing only surface data.

The specified figure name, index, and three-dimensional figure data are registered in the three-dimensional data file IO through the file control section 2.

The file control unit 2 manages graphic names and data positions (pointers) in the file in association with each other. Also,
The following processing is performed depending on the index value.

When index=1, the given formula data is converted into surface data, and the figure name, index, formula data, and surface data are stored in a file.

At this time, the head pointer of the surface data is also managed.

When index = 2, figure name, index,
and store the formula data as is in the file d When index=8, convert the given formula data into surface data, and store the figure name, index, and surface data in the file.

The extraction section 3 extracts data through the file control section 2 and the selection section 11.4 according to the graphic name to be displayed and the mode suitable for the purpose of use. Here, the mode is
For example, there are "high-speed drawing mode" and "precision drawing mode." The storage location of the specified figure is searched through the file control unit 2.

In the "high-speed drawing mode", if both formula data and surface data are stored, the surface data is selected through the selection section 4. On the other hand, in "Precision drawing mode",
If both formula data and surface data are stored, select formula data. The data selected by the extraction unit 3 is extracted and passed to the display unit S, and the data is displayed on the CRT display 61.
．． 62.

(Effects of the Invention) As explained above, the present invention has the following advantages:
By storing and managing both or one of formula data and plane data for one figure, it is possible to reduce file capacity and improve processing efficiency.
