Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a line-symmetrical graphic input device, and more particularly to a line-symmetrical graphic input device having a function of automatically shaping an input graphic into a line-symmetrical graphic.

[0002]

2. Description of the Related Art Conventionally, this kind of line symmetric figure input device is
For example, software "Hanako Ver.2" that runs on a personal computer (made by Justsystem Co., Ltd.)
Is applied as a figure editing device for drawing and editing line figures.

Hanako Ver. 2 Manual "Hanako Ve
r. 2 Introductory Justsystem Co., Ltd. 1989.1
According to “0.2 Second Edition, First Printing”, when a menu such as “drawing” or “editing” is selected using an input device such as a mouse, command options corresponding to each are displayed. For example, if "Draw" or "Rectangle" is selected, a rectangle can be input on the screen.

In order to input a line-symmetrical figure with this conventional line-symmetrical figure input device, a "grid" is displayed on the screen ("Hanako Ver.2 Explanation Edition Just System 199").
0.5.14 2nd edition 4th printing pp. 65 ”) is displayed, and the user inputs the figure while checking the position of the coordinate point so as to be line-symmetrical by himself with reference to it.

Alternatively, input only one side of the axis of symmetry,
"Mirror" command ("Hanako Ver.2 Explanation Edition"
Just System 1990.5.14 2nd edition 4th edition pp. 177 ") is used to symmetrically copy the figure to the opposite side of the axis of symmetry.

A method of inputting a line-symmetrical figure by the "mirror" command will be described with reference to FIGS. First, enter one side of the desired figure (Fig. 18
(See (a)). Next, the "mirror" command is selected and the input graphic is designated. Then, the "leave original figure" mode is selected by the subcommand (see FIG. 18B). The position of the axis of symmetry is determined and determined so that the input graphic and the generated graphic are line-symmetrical (see FIGS. 18C and 18D). In order to input a plurality of line-symmetrical figures using this method, the above operation must be repeated for each figure.

[0007]

In the above-mentioned conventional line-symmetric figure input device, first, when a grid is used,
Since the user has to input the figure by counting the grid cells so that each vertex is symmetrical, there is a problem that attention is required and the operation is cumbersome. Also, in the case of inputting a line-symmetrical figure including a heart-shaped curve, there is a problem that it is almost impossible to input a curved part so as to be symmetrical.

On the other hand, in the input method using the "mirror" command, since only one side of the figure is input, it is difficult to grasp the whole figure of the figure, and such an operation itself is not intuitive. In addition, in order to make a plurality of figures line-symmetric, the above operation must be repeated, which is very troublesome.

As described above, it is difficult to easily input a line-symmetrical figure intended by a user using either method.

In view of the above points, the first object of the present invention is to

An object of the present invention is to provide a symmetric graphic input device.

A second object of the present invention is to specify an arbitrary number of target figures to be subjected to line symmetry shaping when instructing to perform line symmetry shaping processing, and to specify the target figure to be instructed. An object of the present invention is to provide a line symmetric figure input device in which a symmetry axis is automatically generated so that a user can perform line symmetry shaping for each target figure without inputting the symmetry axis.

A third object of the present invention is to specify an arbitrary number of target figures to be subjected to line symmetry shaping when instructing to perform line symmetry shaping processing. Is to provide a line symmetric figure input device capable of inputting an axis of symmetry.

A fourth object of the present invention is to allow a user to input a symmetry axis for an arbitrary number of figures when instructing to perform a line symmetry shaping process, and to set the position of the input symmetry axis. An object of the present invention is to provide a line-symmetrical figure input device in which a figure in Fig. 3 is automatically extracted as a target figure.

A fifth object of the present invention is to provide an axisymmetric figure input device capable of designating a reference element or a reference element for shaping when performing axisymmetric shaping.

The present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the arrangement of a line-symmetrical figure input device according to the first embodiment of the present invention. The axisymmetric figure input device of the present embodiment is an input device 1 such as a keyboard, a mouse and a pen, a data processing device 2 which operates under program control, a storage device 3 for storing information, and an output means 4 such as a display device. And a keyboard or mouse for instructing the data processing device 2 to perform a processing instruction from the user,
A main part of the instruction device 5 is realized by buttons on the screen.

The input device 1 includes a graphic input means 11 for inputting a graphic and a symmetric axis input means 12 for inputting a symmetric axis.

The data processing device 2 includes symmetry determining means 21 for determining the line symmetry of a figure, and symmetry processing means 22 for shaping the figure to be line-symmetric.

The storage device 3 includes a graphic storage means 31 for storing information on the graphic input from the graphic input means 11, and a symmetric axis storage means 32 for storing information on the symmetry axis input from the symmetry axis input means 12. Is provided.

The instructing device 5 comprises line symmetry shaping processing instruction means 51 for instructing to perform line symmetry shaping processing, and target figure instructing means 52 for instructing a figure for line symmetry shaping.

Referring to FIG. 2, the process of the line-symmetrical graphic input device of the first embodiment is performed by a graphic input step A1, a shaping process instruction presence / absence determination step A2, a target graphic instruction step A3, and a symmetry axis input step A4. And an all-target graphic symmetry axis input determination step A5, an undetermined target graphic presence / absence determination step A6, a shaping process start step A7, and a shaping result display step A8.

FIGS. 3A to 3E are views showing an example of a feedback screen to the user displayed on the output means 4 at each time point of the line symmetric figure input device of the first embodiment.

Next, the operation of the line-symmetrical figure input device of the first embodiment thus constructed will be described with reference to FIGS.
This will be described with reference to the example shown in FIG.

When the user inputs a graphic using the graphic input means 11 (step A1), information on the input graphic is stored in the graphic storage means 31. As a method of inputting a figure, as in the case of the conventional line-symmetric figure input device, there are a method of pointing a vertex with a mouse, a method of drawing a locus of a figure with a pen, and the like.

The figure storage means 31 stores coordinates of vertices, angles and side lengths, types of straight lines / curves, and the like (hereinafter, referred to as feature amounts). The graphic stored in the graphic storage means 31 is displayed on the output means 4 as shown in FIG.

After inputting an arbitrary number of figures, the user activates the line symmetry shaping processing instruction means 51 to instruct to perform line symmetry shaping as shown in FIG. 3B (step A2). Yes.)

Then, the target graphic designating means 52 operates as shown in FIG.
As shown in (c), the user is requested to instruct which figure is line symmetrically shaped. By designating the graphic displayed on the output means 4, the user can
An arbitrary number of target figures are designated (step A3). The target graphic designating unit 52 refers to the graphic storage unit 31 to determine which graphic is a shaping target.

Next, as shown in FIG. 3 (d), the user inputs the symmetry axis for each target figure by the symmetry axis input means 12 (step A4). Information about the symmetry axis is stored in the symmetry axis storage unit 32. The symmetry axis stored in the symmetry axis storage means 32 is displayed on the output means 4.

When the symmetry axes are input to all the target figures (Yes in step A5), the symmetry determining means 21
Is a graphic storage unit 31 for each graphic of the target graphics.
It is determined whether or not it is possible to perform line symmetry shaping based on the feature amount such as the coordinates of the vertices of the target graphic stored in the target figure and the information on the symmetry axis stored in the symmetry axis storage means 32 (step A7).

An example of a specific processing procedure of the symmetry determining means 21 will be described with reference to FIGS. 4 and 5. FIG. 4 is a flowchart showing an example of the processing procedure of the symmetry determination means 21. FIG. 5 is a diagram showing an example of the feature amount used in the symmetry determination.

First, the symmetry determining means 21 determines the intersection of the symmetry axis and the target graphic, and determines which vertex or side midpoint of the shape of the target graphic the symmetry axis passes through (step G1). .

Next, the symmetry determination means 21 determines a set of vertices for which symmetry is to be determined (step G2). As shown in FIG. 5, vertices on both sides of the symmetry axis are traced from one vertex (middle point) passing through the symmetry axis to the other vertex (middle point). At this time, the vertices traced n times (n = 1, 2, ...) Are set. In FIG. 5, the vertices a and a ′ and the vertices b and b ′ are a set.

Subsequently, the symmetry determining means 21 obtains the distance between the midpoint of the two vertices in the set and the axis of symmetry (step G).
4). Further, the symmetry determining means 21 calculates the angle between the line segment connecting the two vertices and the axis of symmetry, and calculates the angle difference (absolute value) from 90 degrees (step G5).

The symmetry determining means 21 performs the processing of steps G4 and G5 on all sets of two vertices (No in step G3), and calculates the average value of the distance between the midpoint of the two vertices and the axis of symmetry and 2 The average value of the angular difference between the line segment connecting the vertices and the axis of symmetry is calculated (step G6). When the average values are equal to or less than the predetermined threshold values, the symmetry determination means 21 determines that the target graphic can be shaped in line symmetry.

The target figure determined by the symmetry determining means 21 to be line-symmetrical shapeable is such as the coordinates of the vertices stored in the figure storing means 31 so that the symmetric processing means 22 makes the target figure line-symmetrical. The feature amount is changed and stored again in the graphic storage means 31. The graphic re-stored in the graphic storage means 31 is output by the output means 4 as shown in FIG.
(Step A8).

When the symmetry judging means 21 has carried out the processing of steps A7 and A8 for all the target graphics (No in step A6), the processing is terminated.

According to the line symmetric figure input device of the first embodiment, when an instruction to perform the line symmetry shaping process is given, an arbitrary number of target figures to be subjected to the line symmetry shaping can be designated, and each designated target figure can be designated. On the other hand, by allowing the user to input the symmetry axis, an arbitrary number of line-symmetric figures can be simultaneously input by simple input processing.

FIG. 6 is a block diagram showing the arrangement of a line-symmetrical figure input device according to the second embodiment of the present invention. In the line-symmetrical graphic input device of this embodiment, the data processing device 6 has a target graphic extracting means 23 in addition to the configuration of the data processing device 2 in the line-symmetrical graphic input device of the first embodiment shown in FIG. It's different. In addition, the pointing device 7 of the first embodiment also has a point that the pointing device 7 includes a line symmetric shaping process instructing unit 51 and a shaping process start instructing unit 53 that instructs to actually start the line symmetric shaping process. This is different from the line symmetric graphic input device. Since the other means and the like are configured in the same manner as the corresponding means and the like in the line symmetric figure input device of the first embodiment, the same reference numerals are given to the corresponding means and the like, and detailed description thereof will be given. Is omitted.

Referring to FIG. 7, the processing of the line-symmetrical graphic input device of the second embodiment is performed by a graphic input step A1, a shaping processing instruction presence / absence determination step A2, and a symmetric axis input step B.
1, a shaping process start instruction presence / absence determination step B2, an undetermined target graphic presence / absence determination step A6, a shaping process start step A7, and a shaping result display step A8.

FIGS. 8A to 8E are views showing an example of a feedback screen to the user displayed on the output means 4 at each time point of the line symmetric figure input device of the second embodiment.

Next, the operation of the line-symmetrical figure input device of the second embodiment thus constructed will be described with reference to FIGS.
This will be described with reference to the example shown in FIG.

The graphic input means 11, the line symmetry shaping processing instruction means 51, the symmetry determination means 21, and the symmetry processing means 22.
The operation (steps A1, A2, A6 to A8) is as shown in FIG.
As shown in (a), (b) and (e), the figure input means 11, the line symmetry shaping processing instruction means 51, and the symmetry determination means 21 in the line symmetric figure input apparatus of the first embodiment shown in FIG. Since the operation is the same as that of the symmetrization processing means 22, detailed description thereof will be omitted.

In the line symmetric figure input device of the first embodiment, the user inputs the symmetry axis by the symmetry axis input means 12 after the user has instructed the target figure to be subjected to line symmetry shaping by the target figure instructing means 52. In the line symmetric graphic input device of the second embodiment, as shown in FIG. 8C, when the user inputs a symmetric axis from the symmetric axis input means 12, the target graphic extracting means 23 refers to the graphic storage means 31. Then, the figure at the place where the axis of symmetry is input is determined to be the object figure of line symmetry shaping (step B1). At the same time, the target graphic extracting means 23
Stores the information about the symmetry axis input by the symmetry axis input means 12 in the symmetry axis storage means 32.

After inputting the axis of symmetry, the user instructs the shaping process start instructing means 53 to start the line symmetry shaping process as shown in FIG. 8D (Yes in step B2).
Subsequent operations are the same as in the case of the line symmetric figure input device of the first embodiment.

According to the line symmetrical figure input device of the second embodiment, when the user instructs to perform the line symmetrical shaping process, the user can input the symmetry axis for an arbitrary number of figures and input the symmetry axis. Since it is possible to instruct the target figure to be subjected to line pair shaping at the same time, the input work by the user can be further reduced.

FIG. 9 is a block diagram showing the arrangement of a line-symmetrical figure input device according to the third embodiment of the present invention. The line-symmetrical graphic input device of this embodiment differs from the line-symmetrical graphic input device of the first embodiment shown in FIG. 1 in that the input device 8 is composed of only the graphic input means 11. In addition to the configuration of the data processing device 2 in the line symmetric figure input device of the first embodiment, the data processing device 9 has a symmetry axis generating means 24.
Is different. In addition, other means etc.
Since the corresponding means and the like in the line-symmetrical graphic input device of the first embodiment are configured in the same manner, corresponding means and the like are denoted by the same reference numerals and detailed description thereof will be omitted.

Referring to FIG. 10, the processing of the line-symmetrical graphic input device of the third embodiment is performed by a graphic input step A1, a shaping process instruction presence / absence determination step A2, a target graphic instruction step A3, and an undetermined target graphic presence / absence. The determination step C1, the symmetry axis generation step C2, the symmetry axis existence determination step C3, the shaping processing start step C4, the symmetry axis validity determination step C5, and the shaping result display step C6.

FIGS. 11A to 11D show the output means 4 at the respective points of time in the line symmetric figure input device of the third embodiment.
It is a figure which shows an example of the feedback screen to the user displayed on.

Next, the operation of the line-symmetrical figure input device of the third embodiment constructed as described above will be described with reference to FIGS.
This will be described with reference to the example shown in (d).

Operations of the figure input means 11, the line symmetry shaping processing instruction means 51 and the target figure instruction means 52 (step A)
1 to A3), as shown in FIGS. 11A, 11B and 11C, the graphic input means 11 and the line symmetric shaping processing instruction in the line symmetric graphic input device of the first embodiment shown in FIG. Since the operations of the means 51 and the target graphic designating means 52 are the same,
The detailed description thereof is omitted.

After the target graphic is designated by the target graphic designating means 52, the symmetry axis generating means 24 selects, for each of the target graphics, one of the feature quantities of the graphics stored in the graphic storing means 31. Based on the information on the vertices and sides, a combination of the vertices or the midpoints of the sides that may become the symmetry axis is assumed, and one of them is generated as a candidate for the symmetry axis (step C2). Further, the symmetry axis generating means 24 stores information on the generated symmetry axis candidates in the symmetry axis storing means 32.
If a symmetry axis candidate cannot be generated, the symmetry axis generation unit 24 determines that the specified target graphic is not a line-symmetric graphic (No in step C3).

The symmetry determination means 21 is a graphic storage means 31.
Whether or not the line symmetry can be shaped is determined based on the feature amount of the target graphic stored in (1) and the information of the symmetry axis candidate stored in the symmetry axis storage unit 32 (step C4). If it is determined that the line symmetry cannot be shaped (step C
(No in 5), the symmetry determining means 21 returns the control to step C2, and the symmetry axis generating means 24 generates another symmetry axis candidate (step C2).

The object graphic determined by the symmetry judging means 21 to be line-symmetrical shapeable is such as the coordinates of the vertices stored in the graphic storage means 31 so that the symmetry processing means 22 makes the object graphic line symmetrical. The feature amount is changed and stored again in the graphic storage means 31. The target graphic re-stored in the graphic storage means 3 is displayed on the output means 4 as shown in FIG. 11 (d) (step C6).

When the processing of steps C2 to C6 is performed on all the target graphics (No in step C1), the line symmetric shaping processing ends.

According to the line symmetric figure input device of the third embodiment, when the user gives an instruction to perform the line symmetry shaping process, the user only indicates the target figure, and the line symmetry shaping can be performed without inputting the axis of symmetry. As it is performed, the burden on the user is reduced.

FIG. 12 is a block diagram showing the configuration of the line-symmetrical figure input device according to the fourth embodiment of the present invention. The line symmetric figure input device of the present embodiment is different from the line symmetric figure input device of the third example shown in FIG. 9 in that the pointing device 10 is composed only of the line symmetry shaping processing instruction means 51. .
Since the other means and the like are configured in the same manner as the corresponding means and the like in the line symmetric figure input device of the third embodiment, the same reference numerals are given to the corresponding means and the like, and detailed description thereof will be given. Is omitted.

Referring to FIG. 13, the processing of the line-symmetrical graphic input device of the third embodiment is performed by a graphic input step A1, a shaping process instruction presence / absence determination step A2, an undetermined graphic presence / absence determination step D1, and a symmetry axis generation. Step D2, symmetry axis presence / absence determination step D3, and shaping processing start step D4
And a symmetry axis validity determination step D5 and a shaping result display step D6.

FIGS. 14A to 14C show the output means 4 at the respective points of time in the line symmetric figure input device of the fourth embodiment.
It is a figure which shows an example of the feedback screen to the user displayed on.

Next, the operation of the line-symmetrical figure input device of the fourth embodiment thus constructed will be described with reference to FIGS.
This will be described with reference to the example shown in FIG.

The operations (steps A1 and A2) of the figure input means 11 and the line symmetry shaping processing instruction means 51 are shown in FIG.
As shown in (a) and (b), the operations are the same as those of the graphic input means 11 and the line symmetrical shaping processing instructing means 51 in the line symmetric graphic input apparatus of the first embodiment shown in FIG.
The detailed description thereof is omitted.

When the line symmetry shaping process instructing means 51 is activated, the symmetry axis generating means 24 makes the feature quantity of the figure stored in the figure storing means 31 for every one figure of all the inputted figures. Of the vertices or sides that may become the symmetry axis based on the information of the vertices or sides, among them, a pair is generated as a symmetry axis candidate from among them (step D2). Further, the symmetry axis generating means 24 stores information on the generated symmetry axis candidates in the symmetry axis storing means 32. If a symmetry axis candidate cannot be generated, the symmetry axis generation means 24 determines that the input graphic is not a line-symmetric graphic (No in step D3).

Next, the symmetry determination means 21 performs line symmetry shaping from the feature quantity of the graphic stored in the graphic storage means 31 and the information of the candidate of the symmetry axis stored in the symmetry axis storage means 32. It is determined whether it is possible (step D4). If it is determined that the line symmetry cannot be shaped (step D
(No at 5), the symmetry determining means 21 returns the control to step D2, and the symmetry axis generation means 24 generates another symmetry axis candidate (step D2).

The figure determined by the symmetry determination means 21 to be line-symmetrical shapeable is a feature amount such as the coordinates of the vertices stored in the figure storage means 31 so that the symmetry processing means 22 makes the figure line-symmetric. Is changed and stored again in the graphic storage means 31. The graphic re-stored in the graphic storage means 31 is displayed on the output means 4 as shown in FIG. 14C (step D6).

When the processes of steps D2 to D6 have been performed on all the figures (No in step D1), the line symmetry shaping process ends.

According to the line symmetric figure input device of the fourth embodiment, when the instruction to perform the line symmetry shaping process is given, the symmetry axis is automatically generated for all the figures that are input, and the user can select the individual figures. Since the line symmetry shaping is performed without inputting the axis of symmetry, the burden on the user is reduced.

FIG. 15 is a block diagram showing the structure of the line-symmetrical graphic input device according to the fifth embodiment of the present invention. In the line symmetric figure input device of the present embodiment, the pointing device 100 serves as a shaping reference in the line symmetric shaping process in addition to the configuration of the pointing device 5 in the line symmetric figure input device of the first embodiment shown in FIG. The difference lies in that a shaping reference element designating unit 54 for designating an element or an element to be referred to is provided. Since the other means and the like are configured in the same manner as the corresponding means and the like in the line symmetric figure input device of the first embodiment, the same reference numerals are given to the corresponding means and the like, and detailed description thereof will be given. Is omitted.

Since the operations of 52 and the symmetry determining means 21 are similar, detailed description thereof will be omitted.

When the symmetry determining means 21 determines that the target graphic can be shaped in line symmetry, the user uses the shaping reference element designating means 54 to perform line symmetry shaping in the symmetrization processing means 22, as shown in FIG. As shown in (), a reference element or an element to be referenced for shaping is designated (step E1). For example, fix the position of the figure and adjust the position of the symmetry axis to the figure, fix the position of the symmetry axis and adjust the position of the figure to the symmetry axis, and set the coordinates of the left and right (up and down) vertices of the symmetry axis. Refer to and format, etc. The symmetrization processing means 22 uses the shaping reference element designating means 54.

As described above, according to the present invention, graphic input means, graphic storage means, line symmetry shaping processing instruction means, symmetry axis generation means, symmetry axis storage means, symmetry determination means, symmetry processing means and output. By providing a means to automatically generate the symmetry axis for all the figures input when instructing to perform the line symmetry shaping process, the user can individually set the symmetry axis for the figure. There is an effect that a line symmetry shaping can be performed without inputting, and a user interface for inputting a line symmetry figure with reduced burden on the user can be obtained.

Further, graphic input means, graphic storage means, line symmetry shaping processing instruction means, target graphic instruction means, symmetry axis generation means, symmetry axis storage means, symmetry determination means, symmetry processing means and output means are provided. By specifying an arbitrary number of target figures when instructing to perform line-symmetric shaping processing, the symmetry axis of the target figure is automatically generated,
There is an effect that the user can perform line symmetry shaping without inputting the axis of symmetry individually to the target graphic, and a user interface for inputting a line symmetric graphic that reduces the user's burden can be obtained.

Further, graphic input means, graphic storage means, line symmetry shaping processing instruction means, target graphic instruction means, symmetry axis input means, symmetry axis storage means, symmetry determination means, symmetry processing means and output means are provided. A user interface for inputting a line-symmetric figure that reduces the burden on the user can be obtained by enabling the line-symmetric shaping by simply specifying the target figure and the axis of symmetry when instructing to perform the line-symmetric shaping process. This has the effect.

Further, figure input means, figure storage means, line symmetry shaping processing instruction means, symmetry axis input means, symmetry axis storage means, target figure extraction means, shaping processing start instruction means,
A symmetry determining means, a symmetrization processing means, and an output means are provided so that when a command to perform a line symmetry shaping process is given, a graphic corresponding to the symmetry axis input at the same time as the symmetry axis is extracted as a target graphic. By doing so, line symmetry shaping can be performed on the target graphic without the user designating the target graphic, and thus there is an effect that a user interface for inputting a line symmetric graphic that reduces the user's burden can be obtained.

Further, when the figure is shaped into line symmetry in the symmetrization processing means, a shaping reference element designating means for designating an element serving as a shaping reference or an element to be referred to is added. When performing, there is an effect that a user interface for inputting a line symmetric figure can be obtained in which an element serving as a reference for shaping and an element to be referred to are designated to easily perform the line symmetric shaping desired by the user.
