Abstract

PURPOSE:To reduce access to a data base, and to quickly display a composite pattern by assembling the data attribute of a basic pattern object in a composite pattern object by an object directive type data base, and simultaneously, coordinating previously the procedure attribute of the basic pattern object to it. CONSTITUTION:The displaying instruction of 'house' is received from a user or an application program. The composite pattern object 'house' 1 of the designated 'house' is taken out on main storage. The procedure attribute 2-1 of the basic pattern object 2 coordinated to the data attribute 1-1 of the composite pattern object 'house' 1 is loaded on the main storage, and is started. The sub-routine of the started procedure attribute 2-1 refers to the corresponding data attribute 1-1, and shades all over the inside of the triangular part, for instance, of a roof to constitute the 'house' at a designated position and by a designated color, and displays a contour line by a designated kind of a line and so on.

Description

[Detailed Description of the Invention] [{Already required] A graphic processing method for displaying complex figures using object-oriented data and a single object, and a method for displaying complex figure objects in an object-oriented database. Incorporating the data attributes of basic graphic objects and associating them with the procedural attributes of basic graphic objects, we aim to reduce processing such as accessing the database and quickly display complex shapes. A complex figure object 1 that introduces the data attributes of each basic figure that makes up the complex figure to be constructed, and a basic figure object 1 that has procedural attributes that correspond to the data attributes of the basic figures incorporated into this complex figure object.
In response to display instructions, etc., extracts the corresponding compound figure object 1 from the object-oriented database, and extracts the basic figure object 1 corresponding to the data attribute of the basic figure incorporated therein. The system is configured to activate a procedural attribute, refer to the data attribute, and sequentially display basic figures to display a composite figure.

[Industrial application field]

The present invention relates to a graphics processing method for displaying complex graphics using an object-oriented database. In order to enable users to easily manipulate C figures, systems that implement figure processing on an object-oriented knowledge representation system have become widespread. This object-oriented knowledge representation system has functions such as object access that allow us to efficiently access, join, display, erase, etc. a large amount of basic figure data that composes complex figures such as maps. It is becoming increasingly difficult to move and scale (enlarge/reduce) images, and it is desired to reduce overhead and perform display processing at high speed.

[Prior art and problems to be solved by the invention] Conventionally, as shown in FIG. 3, a composite figure consisting of a plurality of basic figures such as a house, for example a figure representing a roof, a rectangle representing a wall, etc. is displayed. , deletion, movement, scaling, etc., each basic graphic object 22 that makes up the complex graphic objects 1 and 21 "house" is searched from an object-oriented database and displayed. For this reason, the Ohhesod becomes a person who accesses the database for a large number of basic objects 1 from the complex figure object I, extracts the corresponding ones, and joins the corresponding ones from these retrieved objects. There was a problem in that the user could not quickly manipulate the figures.

The present invention incorporates the data attributes of the basic graphic object 11 into the composite graphic object I in the object 1 oriented database 2, and also associates the procedural attributes of the basic graphic object I with this. The purpose is to reduce processing such as database access, and quickly display complex figures.

[Means to solve problems]

Explain the means to solve the problem with reference to Figure ↓.

In FIG. 1, a composite graphic object 1-1 is a composite graphic object that incorporates data attributes 1-1 of each basic graphic forming the composite graphic to be displayed.

Basic figure objects 1 and 2 are compound figure objects.
It is an object that has procedural attributes 2-1 that correspond to the data attributes 1-1 of the basic figure incorporated in 1.

[Sakukawa]

As shown in FIG.
The data attributes 1-1 of each basic figure that composes the complex figure to be displayed in the basic figure object 1 are incorporated into the basic figure object 1. A procedural attribute 1-2 corresponding to the data attribute 1-1 of the figure is provided, and in response to a display instruction, etc., the corresponding composite figure object 1 is retrieved from an object-oriented database, and N. II Start the procedure attribute 2-1 of the basic figure objects 1 and 2 corresponding to the data attribute 1l of the included basic figure, refer to the data attribute Go 1, display the basic figures sequentially, etc., and create a composite figure. I am trying to display etc.

Therefore, by incorporating the data attribute 1-l of the basic figure into the complex figure object l-1 of the object 1-oriented database and associating it with the procedure attribute 2-1 of the basic figure objects 1 and 2, It becomes possible to quickly manipulate (display, etc.) complex figures by reducing the number of database accesses, joins, and other processes.

(Embodiment) Next, the structure and operation of an embodiment of the present invention will be explained in detail with reference to FIGS. 1 and 2.

In II21, the composite figure object 1.1 is an object that has data attributes 1-1 of a basic figure, such as a "house", that controls the complex figure. here,
For the basic figures that make up the complex figure object [.1, data attributes 1-
1 is incorporated. For example, the basic shape is a triangle.
Data attributes 1-1 in the case of , as shown at the bottom, are the triangle, the vertex coordinates of the triangle Pl, P,, P3, the color inside the triangle, the line type of the outline of the triangle, etc. It is constructed from a pointer, etc. associated with the procedure attribute 2-1.

In this embodiment, the basic graphic object 1-2 is composed of procedure attributes 2-1 and the like. The procedure attribute 2-1 is a subroutine that refers to the data attribute 1-1 and performs display, enlargement, reduction, redisplay, movement, copying, etc. For example, if data attribute 1-1 of complex graphic object l-1 is "triangle..." shown on the left of the bottom edge, procedure attribute 2-1
is not shown on the right side of the bottom edge, and becomes a tab routine of "Display triangle", and the subroutine of "Display triangle" that is started refers to the data attribute "Triangle..." and displays the triangle at the specified position. Display in the specified color, specified line type, etc.

Next, following the order C shown in the flowchart of FIG.
The operation of the diagram configuration will be explained in detail.

In FIG. 2, ■ receives an instruction to display "house". This means that it receives an instruction to display "house" from the user or an application program. In response, the processes from ■ to [phase] are activated. be done.

@ retrieves the corresponding tasopple from the DB (database). Then, as shown in FIG. 1, the DB is searched for the composite graphic object I/"house" of the specified "house" and taken out onto the main memory.

■ starts the procedural attribute. This is activated by loading the procedure attributes 2-1 of the basic graphic objects 1 and 2, which are associated with the data attribute 1-1 of the composite graphic object "house" retrieved with @, onto the raw memory.

■Displays “house” by referring to the data attributes of Tasople. This means that the subroutine of procedure attribute 2-1 started in ■ looks up the "house" by referring to the corresponding deck attribute]1.
Fills the interior with the specified color, displays the outline with the specified line type, etc.

[Phase] determines whether it is the end or not. If YES, the process ends. In the case of No, the compound figure object ball 1-
Repeat steps 0 and ■ from 1 to the next basic figure in the same way.

〔Effect of the invention〕

As explained above, according to the present invention, when the data attribute 1-1 of a basic figure is incorporated into a complex figure object I.↓ of an object-oriented database. ! 5, this is associated with the control attribute 2-1 of the Ogi figure objects 1 and 2. Since the structure is adopted, it is possible to reduce the number of processes such as accesses and joins that are hidden in the database, and create complex figures. can be displayed quickly. With this, the Coser can search an object-oriented database for complex figures such as maps, which consist of a large number of basic figures, and easily perform operations such as displaying, deleting, moving, copying, enlarging, and reducing them. Children become possible.
