Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic processing apparatus and method for machine products, and more particularly to shape information such as a shape model and an assembly, and attributes associated with the shape information necessary for design and production. The present invention relates to a graphic processing apparatus and method capable of handling information and information in an integrated manner.

[0002]

2. Description of the Related Art Currently, in CAD systems for machine products, it is necessary to handle not only shape information but also attribute information, that is, design information that cannot be obtained from shape information by inference or calculation. Of these, the method of expressing the shape information has generality to some extent, and the user does not need to change it if it is handled by a standard method. However, regarding the attribute information, the content of the information required for each user,
There are a great variety of expressions and operations. CA
For the D system, it is desired that the user can individually change or add the content, expression method, and operation method of the attribute information, and that the attribute information is expressed in association with the shape information and can be operated. For this purpose, there are roughly three types of conventional methods for expanding the processing function to handle the shape information and the attribute information.

The first method is to newly create a command satisfying the function of processing the shape information and the attribute information requested by the user.

The second method is to create a macro command that is executed in sequence by combining the basic commands or the above-mentioned new creation commands. An example of this conventional method is shown in FIG. In this example, basic command processing 201, 203, 2
04 and the newly created command processing 202, 205 creates one macro command. That is, first, the basic command process 201 is executed, and the result is used as input data, which is the next process, that is, new creation command process 2
02 is executed. Next, the basic command process 201 and the newly created command 202 are executed as input data, and the basic command process 203 is executed. Thus, the processes 202, 203,
204 and 205 must consider the execution result of the processing performed before each. In other words, each command that constitutes the macro command must cooperate with the command that is executed immediately before.

The third method is to select the processing content by mode. That is, a processing program corresponding to all cases is created in advance. Of course, it is impossible to perform a process that is not prepared in advance.

Further, Japanese Patent Laid-Open No. 3-36668 discloses that
A shape generation method for changing the shape by changing the shape parameter is shown.

[0007]

FIG. 4 shows an example of a process of combining shape information and attribute information which a user of the CAD system is going to perform. This is to connect two rectangular parallelepiped shapes 401 and 402. When only shape information is targeted, these are simply joined to
It suffices to generate two large rectangular parallelepiped shapes 403. However, if attribute information is attached to this, different processing is required. For example, the surfaces having the same surface roughness of the surfaces 404 and 405 may be integrated into one surface 4045, but when the surface roughness is different, it is desired to leave them as two surfaces without integrating them. There are cases. Further, even when the same surface roughness is handled, other users may desire a process of integrating surfaces in terms of shape and matching the surface roughness to a higher quality side for other purposes. As described above, the processing according to the attribute information is necessary, and the processing content needs to be variously changed according to the purpose of the user.

However, in the method of creating the first new command shown in the conventional example, all the processing including the shape processing part must be newly created. This means that if a large number of processes in which shapes and attributes are linked are to be performed, most of the processes in the graphic processing device must be newly created. Even the method using the second macro command cannot be handled well. This is because the conventional graphic processing device cannot output information on how each shape element is processed during the shape processing. Further, in the above example, there is no basic command that can be a macro command component, and in the end, all must be newly created. In the third mode selection method, it is necessary to prepare the device in consideration of all the processing methods described above in advance, and it is not possible to meet various requests. Further, in the technique described in Japanese Patent Laid-Open No. 3-36668, the shape element can be changed from the shape parameter, but the content of the shape processing itself cannot be changed, and therefore various processing corresponding to the attribute can be performed. I couldn't.

An object of the present invention is to solve the above-mentioned problems and to provide a graphic processing apparatus and a method thereof in which a user handles shape information and attribute information in association with each other and can easily realize unique processing.

[0010]

[Means for Solving the Problems] The above-mentioned object is to provide an input means capable of receiving an instruction of attribute-based shape processing,
An element processing procedure data generating means for generating element processing procedure data indicating a processing procedure for each element of the shape for performing the shape processing with an attribute instructed by the input from the means, and the element processing procedure data created by the means. Element processing procedure data changing means for changing the element processing procedure data by referring to the attribute attached to the shape, and shape processing for each element of the shape based on the element processing procedure data generated by the means. It is achieved by providing an input device means for receiving an instruction of macro shape processing in a graphic processing apparatus having an element unit shape processing means for performing the above and a display means for outputting shape data obtained by the shape processing of the means. It

[0011]

The element processing procedure data creating means defines processing such as new generation, deletion, transformation, division, integration, contact, and transfer generation for various shape elements, which are suitable for the attribute attached to the shape element. Since it can be changed so that it becomes a process, it is possible to easily cope with a wide variety of process contents.

[0012]

EXAMPLES Examples of the present invention will be described below. Figure 1
It is a block diagram which shows one Example of the apparatus of this invention. The input device 101 such as a keyboard or a mouse sends to the processing device 103 an instruction for macro shape processing instructed by a command, a parameter thereof, and a coordinate value on the display screen by a user operation. The output device 102 receives a command from the processing device 103 and displays a graphic or a character. Memory 10
4 stores shape data 113, attribute data 115, shape attribute corresponding data 116, and element processing procedure data 114. Element processing procedure data creation program 105
Represents the shape to be processed captured from the input device 101 according to the user's macro shape processing instruction.
13), and based on that, create data on which elements are to be newly created, deleted, deformed, divided, integrated, contacted, and transferred, and in what order, and the element processing procedure data is created. It is stored in the memory 104 as 114. The element processing procedure data change program 106
The element processing procedure data 114 is retrieved from the memory 104, the element processing procedure data 1 is referred to by the user by referring to the attribute data 115 and the shape attribute correspondence data 116.
14 is changed and stored in the memory 104. The element-based shape processing program 120 stores the shape data 113, the element processing procedure data 114, and the attribute data 115 from the memory 104.
And shape attribute corresponding data 116 are extracted, shape processing is performed for each element of the shape data 113 based on the element processing procedure data 114, the shape data 113 is changed, and the attribute data 115 and the shape attribute corresponding data 116 are accordingly changed.
To change.

An example of the element processing procedure data 114 is shown in FIG. This is the element processing procedure data 114 when performing the union operation processing of the shapes 401 and 402 shown in FIG.
Of the target element 301 and its processing content 302. As shown in the case of FIG. 4, the stored contents indicate that the surface 404 and the surface 405 are integrated into one surface, and the line 406 and the line 407 are deleted.

The element processing procedure data 114 is different if the attribute information is different even if the macro processing contents (a series of processing such as integration, deletion, ...) Are the same. Therefore, the procedure cannot be created assuming all cases, and in the present invention, the element processing procedure data creation program 1
This is handled by the processing of the element processing procedure data changing program 106 for changing the element processing procedure data created by 05.

FIG. 5 shows the element processing procedure changing program 1
Fig. 16 shows a block diagram of 06. Here, first, the attribute data storage program 132 causes the input device 10 to
The attribute data 134 input from 1 is read and stored in the memory 104. 6 and 7 show an example of the storage, and an attribute id 601 representing an index in the attribute data.
And attribute contents 602. FIG. 6 corresponds to the example of FIG. 4, and attribute contents 408 and 40 with attribute id = 1 and 2
9 is the same (surface roughness is represented by the number of ∇ marks). On the other hand, FIG. 7 is the case of the example of FIG. 8, and the attribute id =
The attribute contents 408 and 801 of 1 and 2 are different.

Next, the shape attribute data storage program 13
3, the shape attribute correspondence data 116 indicating the correspondence between the target element and the attribute data is created from the input attribute data and stored in the memory 104. FIG. 9 and FIG. 10 show the storage example, and the target element 901 and the attribute id 601 are shown.
It consists of The target element 901 is an element of the shape data 113 indicating the input element, and has an attribute id 601.
Is the attribute id of the attribute data 115 having the input attribute content. FIG. 9 corresponds to the case of FIG. 4, and the target element 90
Reference numeral 2 indicates the surface 404, target element 903 indicates the surface 405, attribute id 904 indicates the finishing accuracy 408, and attribute id 905 indicates the finishing accuracy 409. Similarly, FIG.
It corresponds to the case of.

Next, the attribute data reference program 130 converts the attribute data of the target element of the element processing procedure data 114 to the attribute data 1 via the shape attribute correspondence data 116.
Reference from 15. Then, the attribute-specific element processing procedure data changing program 131 changes the element processing procedure data as intended by the user according to the element processing procedure data and the referenced attribute data.

FIG. 11 is a diagram showing a schematic processing flow of the program 131 for changing the shape processing procedure according to the finishing accuracy of the surface. In processing 1101, the element processing procedure data 114 shown in FIG. Take in. Next process 1
At 102, the attribute information of the target element stored in the fetched element processing procedure data is converted into the shape attribute correspondence data 116.
Via the attribute data 115 via. This behavior
The surface 404 will be described with reference to FIGS. 6 and 9. First, the target element surface 404 is searched from the shape attribute corresponding data 116 in FIG. 9 to obtain the corresponding attribute id 904. Next, the attribute id of the attribute data shown in FIG. 6 is searched from the value 1 of the obtained attribute id 904. Then, the finishing accuracy ▽▽ of the attribute contents corresponding to the attribute id obtained here is obtained. In FIG. 4, face 404
The data corresponding to the shape attribute is represented by a symbol 408a, and its finishing accuracy is represented by a symbol 408. In the case of the surface 405, the shape attribute corresponding data is represented by the symbol 409a, and its finishing accuracy is represented by the symbol 409. The same applies to FIG.

In the next processing 1103 of the attribute-based element processing procedure data change program 131, a determination processing is performed in which the finishing accuracy of the extracted attribute information is compared and the processing is distributed. If the surface 404 and the surface 405 have the same finishing accuracy, the process 1104 is executed, and if they are different, the process 1105 is executed. In the case of FIG. 4, since the finishing precisions 408 and 409 are the same, the processing 1104 is executed. In the case of FIG. 8, the finishing precisions 408 and 801 are different, so the processing 1105 is executed. In process 1104, the surfaces 404 and 405 having the same finishing accuracy are integrated to generate a new surface, so that the first element processing procedure data in FIG. 3 is left as it is. Then, the line deletion processing (second and third data) related thereto is also left as it is. The result is
As shown in FIG. 4, a new surface 4045 and finishing accuracy 4089 which is attribute data are generated, and shape attribute corresponding data 4089a which correlates them is newly generated. on the other hand,
In the processing 1105, the finishing accuracy is different, and the surface 4
Since the 04 and the surface 405 are not integrated, the first and second element processing procedure data are deleted. As a result, as shown in FIG. 8, only the line 407 is deleted and the others are the same as those before the shape processing.

When the processing of the element processing procedure data changing program 106 of FIG. 1 is completed as described above, the processing of the element unit shape processing program 120 is performed next. FIG.
Reference numeral 2 is a block diagram of the program 120. First, in the process allocating 107, the element process procedure data 114 is taken out from the memory 104 and allocated to the process corresponding to the process procedure. After the distribution, referring to the shape data 113, the attribute data 115, and the shape-attribute correspondence data 116, preprocessing is performed by the type-specific preprocessing execution program 108 for the element processing of each type of shape element. Data 115, shape attribute corresponding data 11
6 is changed, and then element processing is performed on each type of shape element by the type-specific element processing program 109, and shape data 113, attribute data 115, and shape attribute correspondence data 1
16. Finally, the type-specific post-processing execution program 110 performs post-processing on the element processing of each type of shape element, and changes the shape data 113, the attribute data 115, and the shape-attribute corresponding data 116.

Another embodiment of the element unit shape processing is shown in FIG. This is a type preprocessing registration program 111 for registering preprocessing executed by the type preprocessing execution program 108 and a type for registering postprocessing executed by the type postprocessing execution program 110 in the embodiment of FIG. This is an embodiment in which another post-processing registration program 112 is added.

In these embodiments, the processing procedure of all types of shape elements such as surfaces, lines and points is handled as the element processing procedure data. In this way, however, when processing surfaces is integrated and when they are not integrated. It is necessary for the element processing procedure data changing program 106, which is an additional processing by the user, to understand and change all of what the surrounding lines and points will be. Since this is very troublesome, the first element processing procedure data creation program 105 generates only the processing data related to the surface, and the element processing procedure data change program 106 handles only the data related to the surface, and then the element processing after the modification. A method is conceivable in which processing procedure data for all elements such as faces, lines, and points are created based on the procedure data, and the following processing is performed. Thus, it is within the scope of the present invention to divide the element processing procedure data creating means into several parts and execute them in separate steps. Hereinafter, the processing content will be described using a specific example.

14 to 16 show an example of a grooving process for forming a groove in a shape. FIG. 14 shows the state of the attribute information associated with the shape and the shape element before and after the grooving process is performed. The shape 1401 of FIG. 14A is a grooved shape, and the shape of FIG. 1402 is a groove shape, same figure (c)
The shape 1403 indicates the shape of the result of the grooving process.
Surface 1404 of shape 1401 and surface 140 of shape 1402
5, surface 1406, surface 1407, finish attribute 1421, 1 shown by inverted triangle as attribute information by shape attribute corresponding data 1421a, 1422a, 1423a, 1424a.
422, 1423, and 1424 correspond. FIG.
Shows a schematic flow of the grooving processing according to the present invention. First, in the element processing procedure data creation program 105, the shape data of the shapes 1401 and 1402 are fetched,
Create element processing procedure data. FIG. 16 shows the created element processing procedure data. In this example, the shape 1401
When the groove shape 1402 is attached to the surface 1404 of the shape 1401, the element processing procedure data is that the surface 1404 of the shape 1401 is divided and the surfaces 1405, 1406, and 1407 of the shape 1402 are divided.
Is transferred and a new surface is generated.

Generally, the change processing by the element processing procedure data change program 106 is subsequently performed,
For simplicity, it is assumed here that no change occurs in the change process, and the process proceeds to the following.

Returning to FIG. 15, the processing distribution program 107 (the distribution means in FIG. 12) judges the processing contents of the element processing procedure data and proceeds to the corresponding processing.
If the processing content is division processing, surface division processing 109-1 (type-specific element processing in FIG. 12) for the target element of the element processing procedure data is performed. Specifically, the surface 1404 of the shape 1401 is divided into the surface 1408 of the shape 1403 and the surface 1404 of the shape 1403.
409 is generated. Next post-processing 110-1, 110-2
(Post-processing in FIG. 12) is a program for performing user-specific processing registered by the type-specific post-processing registration means 112. In this example, the processing for determining the finishing accuracy of the surfaces 1408 and 1409 is registered. Specifically, the finishing accuracy of the surfaces 1408 and 1409 is set to be the same as the finishing accuracy 1421 of the surface 1404 before division. If the processing content is transfer generation, transfer generation processing 109 of the target element
-2 (type-specific element processing in FIG. 12) is performed. That is, the surface 1405, the surface 1406, and the surface 1407 of the shape 1402 are transferred to transfer the surface 1410, the surface 1411, and the surface 141 of the shape 1403.
Generates 2. Then, as in the case of division, post-processing 110
-2. The contents of the processing program registered by the user in this post-processing include the finishing accuracy of the surface 1410, the surface 1411 and the surface 1412, the surface 1405, the surface 1406 and the surface 14 of the transfer source.
This is a process of setting the finishing accuracy to be 07. The shape resulting from this grooving process and the finishing accuracy that is the attribute information associated with it are as shown in the shape 1403. Thus, by registering the attribute processing method for each processing content of the element processing procedure data, the user can easily perform an operation in which the shape information unique to the user and the attribute information are linked. It should be noted that whether or not the procedure has ended is checked at 105a, and if all the steps have been processed, the process ends.

17 to 21 show an embodiment of a surface matching process for matching the surfaces of two shapes. Shape 170 of FIG.
Reference numerals 1 and 1702 are surface-matching shapes, and surfaces 1703 and 1704 having respective shapes are in contact with each other. Finishing accuracy 1713, 1714 is attribute information associated with both surfaces by shape attribute corresponding data 1713a, 1714a.
Is attached. FIG. 18 shows a schematic flow of the face matching processing according to the present invention. First, the element processing procedure data creation program 105 fetches the shape data of the shapes 1701 and 1702 to obtain the element processing procedure data. Create the data. FIG. 19 shows the contents of the element processing procedure data created. In this example, surface 1703 of shape 1701 and shape 17
02 surface 1704 is shown to be touched.

The next element processing procedure data changing processing is assumed to be omitted in this case, and the shape element processing is performed for each item of the element processing procedure data. First, in the processing distribution processing 107, the processing content of the element processing procedure data is judged, and the processing proceeds to the corresponding processing. If the processing content is contact, contact processing 109 of the surface with respect to the target element is performed. Specifically, the shape 1 is formed so that the surface 1703 and the surface 1704 match.
701 or shape 1702 is moved. Next, the post-processing 110 unique to the user is performed. FIG. 20 shows an example of the post-processing 110. In this embodiment, the finishing accuracy corresponding to the surface 1703 and the surface 1704 is searched, and if the accuracy is low, the accuracy is set high. This is because, in mechanical design, it is generally not possible to match surfaces with low finishing accuracy, and this post-processing 110 is an embodiment in which finishing accuracy is not lowered. FIG. 21 shows the result of the surface matching processing, and the finishing accuracy corresponding to the surfaces 1703 and 1704 is higher than that before the surface matching processing of FIG.

22 to 24 show an embodiment in which the processing of the union operation of two shapes is performed. FIG. 22 shows the shape before and after the union operation processing and the shape attribute correspondence data 2
Attribute information 2 associated by 221a and 2222a
221, 2222 are shown. The type of material is attached to the shape as the attribute information. FIG. 22A shows a shape 220.
1 and the shape 2202 are made of the same iron material. on the other hand,
In FIG. 22B, the material of the shape 2201 is iron and the shape 2202.
This is the case when the material is copper and the material is different. FIG. 23
Shows an outline flow of the union operation processing in the present invention. First, the element processing procedure data creation program 10
In step 5, the shape data of the shapes 2201 and 2202 is fetched and element processing procedure data is created. FIG. 24 shows the created element processing procedure data. In the description of this embodiment, attention will be paid to the aspect. The element processing procedure data is the surface 2205.
And face 2210 are deleted, face 2206 and face 2211, face 2207 and face 2212, face 2208 and face 2213, face 2
209 and surface 2214 are shown to be integrated.

Next, in the element processing procedure data changing program 106, the shape 2 is changed from the target element of the element processing procedure data.
The material which is the attribute information of 201 and 2202 is searched, the materials of two shapes are compared, and the element processing procedure data is changed. In FIG. 22A, since the materials are the same, the surfaces are integrated to generate a new surface, so the element processing procedure data is left as it is. On the other hand, in (b) of FIG. 22, since the materials are different, the surfaces are not integrated and the shapes are not unified,
Delete the element processing procedure data and the integration item.

Next, shape element processing is performed for each item of the element processing procedure data. Processing distribution program 10
In step 7, the processing contents of the element processing procedure data are judged and distributed to the corresponding processing. If the processing contents are deleted, the deletion processing 1
09-1 is executed, and if it is integrated, integration processing 109-2 is executed.
Shape element processing is performed for all element processing procedure data, and the processing is ended. As a result, when the materials are the same, as shown in FIG.
As shown in (a), one shape 2203 is formed. When the materials are different, as shown in FIG. 22B, the divided shapes 2201 and 2202 are obtained.

Although the embodiment of the present invention has been described in detail above, when the element processing procedure data is changed from various shapes, their processing contents, and attributes attached to the shapes,
The modification method is described by taking the attributes of surface finishing accuracy and material as an example. In general, there are various attributes, and it is more efficient if you set in advance the method of processing that combines these attributes and the shape / processing content and use them. Processing becomes possible. In addition, if an attribute, shape, or processing content other than those set in advance occurs, a means for inquiring the processing method is provided to the user, and the processing is performed while receiving the response from the user and recording the processing method. If the same case occurs again, the recording can be used to further facilitate the processing.

[0032]

According to the present invention, element processing procedure data for new generation, deletion, deformation, division, integration, contact, and transfer generation of shape elements to be performed during shape processing and generation of the generated element processing procedure. There is an effect that the processing for changing the data as intended by the user can be easily performed by referring to the attribute information attached to the target element, and the shape processing for each element performed based on the element processing procedure data. On the other hand, since the pre-processing and post-processing unique to the user can be registered, there is an effect that the operation of linking the shape information and the attribute information unique to the user becomes easier.
