Description

[0001]
[Industrial applications]
According to the present invention, when a plurality of graphics are created / edited on a display device by a computer, the graphics elements can be associated and edited.Figure editing deviceAbout.
[0002]
In order to create / edit a figure, the position of each figure element and its deformation are specified, but when combining multiple figure elements, the positional relationship between these figure elements must be considered. You need to edit it. Further, it is necessary to be able to handle a group of figures having a certain relation together as a part, including their positional relation.
[0003]
[Prior art]
In a graphic processing system using a computer, it is often necessary to associate a plurality of figures individually created on a display device and handle them as one figure. For example, there is a case where a figure of a handle of a bicycle, a figure of a body frame, a figure of a saddle portion, a figure of a front wheel, a figure of a rear wheel, and the like are individually created and combined to form a figure of a bicycle. In addition, it may be necessary to configure the graphic of each part of the steering wheel and the body frame by a combination of further graphic parts.
[0004]
In the conventional technology, when a plurality of figures are used as a part including a positional relationship, the positions of the figure groups at the time of the parts are stored as a group, and the entire group is regarded as one figure. The transformation, rotation, and movement of the object were realized.
[0005]
[Problems to be solved by the invention]
However, in the conventional method, in order to deform a specific figure in the group of figures once, it is necessary to solve the group of figures and perform a deformation operation. Since all the positional relationships with other figures disappear, there is a problem that the editor must deform or move other figures in accordance with the deformation.
[0006]
For example, if the shape of the bicycle handle and the shape of the body frame are related and grouped, they are treated as an integrated shape, so the handle alone cannot be made larger or smaller. It had to be enlarged or reduced, including the body frame. That is, when only the steering wheel is enlarged, the grouping of the steering wheel and the body frame is temporarily canceled, and only the steering wheel is enlarged. Then, the position of the enlarged steering wheel and the original body frame are adjusted, and the group is again formed. Had to be converted.
[0007]
SUMMARY OF THE INVENTION The present invention solves the above problems, and enables a group of figures having a certain relation, including their positional relations, to be collectively handled as a part, and also edits each of the related graphic elements. It is an object of the present invention to automatically edit related graphics according to the type of association by operation.
[0008]
[Means for Solving the Problems]
FIG. 1 is a diagram illustrating the principle of the present invention.
In FIG. 1, reference numeral 10 denotes a processing device including a CPU and a memory, 11 denotes a display device for displaying a figure to be created / edited, 12 denotes a position specifying device for specifying a position on a display screen such as a mouse or a keyboard, and 13 denotes a position specifying device. A graphic information storage unit, 14A and 14B are graphic header information having management information on the graphic, 15A and 15B are shape determining point information on points for determining the shape of the graphic, and 16 is related to a shape determining point of another graphic. Referenced point information on a point, 17 is an association processing means, 18 is a graphic operation processing means, 20A and 20B are figures to be edited, 21 is a reference point, and 22 is a reference point defined in relation to the reference point 21. , 23 represent predetermined binding points in the figure.
[0009]
The graphic information of each graphic displayed on the display device 11 includes graphic header information 14 and shape determining point information 15 for determining the shape of the graphic. Further, in the present invention, when a point in a figure is related to a shape determining point of another figure, the information is stored in the figure information storage unit 13 as referenced point information 16. The shape determining point of another figure related to the referenced point is called a reference point.
[0010]
The associating processing unit 17 inputs the reference / reference relationship between the shape determination point for determining the shape of the graphic and an arbitrary point on another graphic from the position specifying device 12, thereby obtaining the reference point information. 16 is a processing means for creating pointer information 16 and setting pointer information to the referenced point information 16 in the corresponding shape determination point information 15.
[0011]
When the referenced point moves due to the movement or deformation of the figure including the referenced point, the figure operation processing means 18 moves the reference point referring to it in cooperation with the referenced point, and moves the figure having the reference point. Alternatively, it is a processing unit that performs editing for deformation.
[0012]
The processing according to the present invention is performed as follows.
The associating processing means 17 transmits, for example, instruction information for associating a reference / reference with the reference point 21 in the graphic 20B and the referenced point 22 in the graphic 20A shown in FIG. Input from the position designation device 12. When the association instruction information is input, the reference point information 16 having the position information of the reference point 22 and the like is created, and the reference point information 16 is pointed from the shape determination point information 15 indicating the reference point 21. I do.
[0013]
When the graphic 20A is moved by the editing operation on the graphic 20A, for example, as shown in FIG. 1C, the referenced point 22 also moves. When detecting the movement of the referenced point 22, the figure operation processing unit 18 examines the referenced point information 16, obtains the shape determination point information 15 of the reference point 21 referring to the referenced point 22, 22, the figure 20B having the reference point 21 is moved or deformed. In the example of FIG. 1C, as the referenced point 22 moves upward, the reference point 21 also moves upward, and the figure 20B is deformed. In the case of this example, the right corner point at the base of the figure 20B is defined in advance as the binding point 23, so that the binding point 23 is not moved, and the figure 20B is deformed so as to extend in the vertical direction.
[0014]
The reference / reference relationship includes at least rotation, deformation, and a similar deformation type for enlarging or reducing. This type is determined by the input of the association instruction information or the positional relationship between the binding point 23 and the reference point 21 in the same figure. Note that the binding point 23 is one or more points that can be set in advance for each figure, and this information is stored in the figure information storage unit 13.
[0015]
When the reference point 21 is in a rotational reference relationship with respect to the referenced point 22, the figure 20 </ b> B having the reference point 21 rotates around, for example, the binding point 23 as the referenced point 22 moves. If the reference point 21 is in a deformed reference relationship with respect to the referenced point 22, the figure 20B having the reference point 21 is moved as the referenced point 22 moves, for example, as shown in FIG. Deform. When the reference point 21 has a similar deformation reference relationship with respect to the referenced point 22, the graphic 20 </ b> B having the reference point 21 is deformed so as to be enlarged or reduced with the movement of the referenced point 22.
[0016]
[Action]
In the present invention, the point that determines the shape of the figure 20B is set as the reference point 21, is related to the referenced point 22 on another figure 20A, and the related information is stored in the figure information storage unit 13, so that the figure 20A The figure 20B having the reference point 21 can be deformed / moved so that the relationship specified in advance is maintained even when the figure 20B is deformed or moved by the editing operation performed by the position specifying device 12.
[0017]
Further, when another shape determining point of the graphic 20B having the reference point 21 such as the binding point 23 is moved downward by the position specifying device 12, the relationship between the reference point 21 and the referenced point 22 is maintained. The figure 20B can be deformed so as to extend long downward.
[0018]
【Example】
FIG. 2 is a diagram illustrating an example of a data structure of graphic information according to the embodiment of the present invention.
For example, the reference / reference relationship between the graphic 20A and the graphic 20B shown in FIG. 2A is managed by a data structure as shown in FIG.
[0019]
Graphic header information 14A, 14B is provided for each graphic. The graphic header information 14A (similarly for 14B and the like) has information on a rectangular range occupied by the graphic (this is called an extent), information on the number of shape determination points, and a pointer to the top shape determination point information 15A. . Further, it has pointer information to shape decision point information defined as a binding point in the figure.
[0020]
The extent of the graphic 20A shown in FIG. 2A is an area in the range shown by the dotted rectangle, and the extent information in the graphic header information 14A includes the coordinates (x0, y0) of the point at the upper left corner of the extent. , Extent width w, and extent height h. The shape determination point information 15A has position information (x1, y1) relating to the vertices of the figure 20A, pointer information to the next point, and the like. When the shape determination point is a reference point associated with a point of another figure, a field for pointing to the referenced information and a field indicating the type of reference are provided in the shape determination point information 15A. Have been.
[0021]
The shape determination point information 15B shown in (b) of FIG. 2 is information of the shape determination point regarding the reference point 21 in (a), and the referenced point information 16 is information of the referenced point 22. The referenced point 22 does not need to be a shape determination point, but is an arbitrary point depending on the shape determination point of the figure 20A. Here, assuming that the position of the referenced point 22 depends on three shape determination points a, b, and c, the referenced point information 16 includes pointers to those points and a degree of dependence k for each point._a, K_b, K_cIs set.
[0022]
As shown in FIG. 2C, the coordinates of each of the points a, b, and c are respectively represented by (x_a, Y_a), (X_b, Y_b), (X_c, Y_c), And the coordinates of the referenced point 22 are (x_p, Y_p). Dependency k from three points_a, K_b, K_cIs
x_ak_a+ X_bk_b+ X_ck_c= X_p
y_ak_a+ Y_bk_b+ Y_ck_c= Y_p
k_a+ K_b+ K_c= 1
Is a value obtained as a solution to the simultaneous equations
[0023]
The referenced point information 16 is dynamically created by the association processing unit 17 and has mutual pointer information between the reference point 21 and the shape determination point information 15B as the reference point 21. If there are a plurality of referenced points in the figure 20A, it has pointer information to the next referenced point information.
[0024]
FIG. 3 is a diagram illustrating an example of modification reference according to the embodiment of the present invention. In the figure, reference numeral 30 denotes a cursor indicating an operation position on the screen, 31 denotes an icon for designating various operations, and 32 denotes a display screen.
[0025]
A mouse is used as the position designation device 12 shown in FIG. 1, and the position of the cursor 30 changes according to the operation of the mouse. As shown in FIG. 3A, an icon 31 for instructing the operation of the deformation reference is selected by the cursor 30, and the figures 20A and 20B to be related are further selected.
[0026]
Here, when associating the shape determination point at the upper right of the figure 20B with one point on the lower side of the figure 20A, the cursor 30 is moved to the upper right point of the figure 20B as shown in (b) of FIG. , Press the mouse button. Then, while the mouse button is pressed, the cursor 30 is moved as shown in FIG. The operation of moving the cursor 30 with the mouse button pressed in this manner is called dragging.
[0027]
As shown in (d) of FIG. 3, the cursor 30 is moved to a point to be related on the graphic 20A, and when the drag is completed, the end point of the drag is changed to the reference point as shown in (e) of FIG. The figure 20B is transformed such that the reference point 21 which is recognized as 22 and is the drag start point on the figure 20B matches the position of the referenced point 22.
[0028]
The associating processing means 17 shown in FIG. 1 performs the above processing for the associating operation, and stores the reference / referenced relationship between the reference point 21 and the referenced point 22 in the graphic information storage unit 13 and the relationship. Is set as information indicating that is a transformation reference.
[0029]
After such graphic association is performed, if an operation of moving the graphic 20A to the left is performed, for example, as shown in FIG. 3F, the referenced point 22 also moves to the left. Therefore, the reference point 21 is moved accordingly, and the graphic 20B is automatically edited so that the horizontal width of the graphic 20B is reduced. As shown in FIG. 3G, when the graphic 20A moves rightward, the reference point 21 also moves rightward, and the graphic 20B is deformed long. The above graphic operation processing is executed by the graphic operation processing means 18 shown in FIG. 1 based on the reference / referenced relationship information in the graphic information storage unit 13.
[0030]
FIG. 4 is a diagram illustrating an example of rotation reference according to the embodiment of the present invention. As in the example shown in FIG. 3, a mouse is used as the position specifying device 12, and the position of the cursor 30 is changed by operating the mouse.
[0031]
As shown in FIG. 4A, an icon 31 for instructing a rotation reference operation is selected by the cursor 30, and graphics 20A and 20B to be related are further selected.
Here, when the shape determining point at the tip of the arrow of the graphic 20B is related so that it always points to one point on the left side of the graphic 20A, as shown in FIG. Bring to the tip of the arrow and press the mouse button. Then, while the mouse button is pressed, the mouse is dragged as shown in FIG. By dragging, the figure 20B rotates, and a rubber band as indicated by a dotted line is displayed.
[0032]
When the dragging is completed at the point to be related on the graphic 20A, the graphic 20B faces the drag end point (reference point 22) on the graphic 20A with the binding point 23 as the center, as shown in FIG. Rotate and re-display.
[0033]
In order to maintain this relationship, the association processing means 17 shown in FIG. 1 stores in the graphic information storage unit 13 a reference / reference relationship between the reference point 21 and the referenced point 22 and information indicating that the relationship is a rotation reference. Set.
[0034]
After such graphic association is performed, when an operation of moving the graphic 20A downward is performed, for example, as shown in (e) of FIG. 4, the graphic operation processing means 18 based on the rotational reference relation information , The reference point 22 and the reference point 21 operate in cooperation with each other, and the rotation operation of the figure 20B is performed so that the reference point 21 at the tip of the arrow of the figure 20B faces the direction of the reference point 22. Is
[0035]
FIG. 5 is a diagram showing an example of similarity modification reference according to the embodiment of the present invention.
The similar deformation is an operation of enlarging or reducing the figure 20B having the reference point 21 according to the movement of the referenced point 22. After selecting the similar deformation operation, the reference point 21 on the graphic 20B is related to the reference point 22 on the graphic 20A by the same operation as in FIG. 3 or FIG. wear. The association processing means 17 sets the reference / reference relationship between the reference point 21 and the referenced point 22 in the graphic information storage unit 13 and information indicating that the relationship is a similar deformation reference.
[0036]
After the association of the figures is performed, when the operation of moving the figure 20A is performed, for example, as shown in (b) of FIG. 5, the figure operation processing unit 18 based on the similar deformation reference relation information is performed. Through the processing, the reference point 21 is operated so as to operate in cooperation with the referenced point 22, a new position of the reference point 21 is calculated, and the figure 20B is enlarged or reduced.
[0037]
FIG. 6 is a diagram illustrating an example of movement reference according to the embodiment of the present invention.
A moving reference is a type of deformed reference. 6A, when the binding point 23 of the graphic 20B is selected as the reference point 21, that is, when the binding point 23 and the reference point 21 match, as shown in FIG. Become.
[0038]
In the case of moving reference, as shown in FIG. 6B, when the graphic 20A having the referenced point 22 moves, the graphic 20B is also moved as it is due to the relationship between the reference point 21 and the referenced point 22. Is
[0039]
FIG. 7 is a diagram illustrating an example of a deformation operation by a binding point according to the embodiment of the present invention.
As described in the example of FIG. 3 and the like, the type of reference can be specified by the icon 31 to determine the rotation or deformation operation. However, the deformation operation is determined by the positional relationship between the binding point 23 and the reference point 21. It can also be done.
[0040]
In FIG. 7, the position of the reference point 21a is a position of the reference point before the reference point moves, and the position of the reference point 21b is a virtual position in the direction in which the reference point is dragged along with the movement of the reference point. Indicates the position.
[0041]
For a two-dimensional figure as shown in FIG. 7A, a binding point 23 is defined at the upper left point, and the next point on the same side as the binding point 23 is a reference point 21a. Suppose. Assuming that the reference point 21a is pulled to the position of the reference point 21b by the movement of the referenced point (not shown), the graphic operation processing unit 18 needs to perform uniaxial deformation based on the positional relationship between the binding point 23 and the reference point 21a. Then, the rectangle is stretched as shown by the dotted line in (a).
[0042]
When the reference point 21a coincides with the binding point 23, the entire figure is moved in parallel with the binding point 23 (reference point) with the movement of the referenced point, as indicated by the dotted line in (b).
[0043]
When the reference point 21a is not a vertex but a point on a side, the figure is rotated around the binding point 23 in the direction of the reference point 21b, which is the direction of the referenced point, as shown in (c).
[0044]
Further, as shown in (d), when the reference point 21a is at a position diagonal to the binding point 23, the rectangle is biaxially deformed, and the figure is similarly deformed (enlarged / reduced) to the position of the reference point 21b. .
[0045]
Even when the figure is a three-dimensional figure, similarly, for example, the deformation operation is determined as follows based on the positional relationship between the binding point 23 and the reference point 21a.
FIG. 7E shows an example of uniaxial deformation. When the reference point 21a is the next point on the same side as the binding point 23, the rectangular figure is stretched in the direction of the reference point 21b.
[0046]
If the reference point 21a is a diagonal point that is not on the same plane as the binding point 23, a three-dimensional similarity transformation is performed on the three-dimensional figure as shown in FIG. Let it.
[0047]
When the reference point 21a is on a diagonal point on the same plane as the binding point 23, as shown in (g), biaxial deformation is performed up to the position of the reference point 21b to expand and contract the length and width. FIG. 7H shows an example of uniaxial rotation. In this example, two points, a binding point 23-1 and a binding point 23-2, are defined as binding points. Assuming that a point on the side of this figure is a reference point 21a and this is pulled to the reference point 21b with the movement of the referenced point, a cubic point is set about the axes of the binding points 23-1 and 23-2. The original figure is rotated as shown by the dotted line.
[0048]
FIGS. 7A and 7B show an example of a reference editing operation on a continuous line. For example, as shown in FIG. Accordingly, the figure is deformed up to the reference point 21b by one-point deformation. When the reference point 21a is the binding point 23, the entire figure is translated as shown in (nu).
[0049]
Note that the example shown in FIG. 7 is an example of a deformation operation of a figure referring to a referenced point. In the present embodiment, instead of moving the referenced point, reference is made directly from the position of the reference point 21a using a mouse or the like. Even when the shape determination point is dragged to the position of the point 21b, the figure is edited by the same determination of the deformation operation.
[0050]
FIG. 8 is an explanatory diagram of a grip display according to the embodiment of the present invention.
In the case of the present invention, when selecting a point to have a reference / referenced relationship, it is necessary to determine on the screen on the display device 11 which point is a shape determination point, in particular, which point is a binding point. You need to be able to identify it quickly. In addition, it is necessary to be able to immediately distinguish points defined as reference points from points that are not reference points.
[0051]
Therefore, in the present embodiment, a point that is a candidate for designation of a figure editing operation is referred to as a “grip”, and the grip can be displayed with a specific mark. The grip includes a binding point grip indicating a binding point and a normal grip other than the binding point.
[0052]
If the point is not selected as an operation target, the grip is usually displayed as a square mark as shown in FIG. On the other hand, the binding point is displayed as a diamond-shaped figure as shown in (b). When those points are selected as operation targets by the position specifying device 12 shown in FIG. 1, the marks are enlarged and displayed as shown in (c) or (d), respectively. Further, when these grips are not reference points, they are displayed as marks shown in the upper part of (a), and when they are reference points, they are displayed as white marks in the lower part of (a). For example, the binding point grip may be displayed in another shape such as a circle, or each mark may be displayed so as to be identified by color.
[0053]
These marks are generally unnecessary after the creation / edit of the figure is completed. Therefore, in this embodiment, the mode is switched between the grip non-display mode and the grip display mode automatically when a figure is selected or by a display mode selection designation operation.
[0054]
In the grip non-display mode, when a figure is a rectangle, only the shape of the figure is displayed as shown in (b) of FIG. When the grip display mode is selected, grips are displayed according to the type of each shape determination point, as shown in (c) of FIG. In this example, nine grips are provided for a rectangular figure. Although not shown, if the figure is a circle, for example, a rectangular figure surrounding the circle is assumed, and nine grips are automatically provided at positions corresponding to the grip positions.
[0055]
FIG. 9 is an explanatory diagram of the association processing according to the embodiment of the present invention. The associating processing means 17 shown in FIG. 1 associates a plurality of figures by the processes (a) to (g) shown in FIG.
[0056]
(A) The designation of a figure reference designation mode such as deformation reference, rotation reference, and similar deformation reference is input. This processing may be executed after the figure selection according to the following (b).

(D) If the grip on the selected figure is dragged by operating the mouse button, the shape determination point of the drag start point is recognized as a reference point.
(E) The drag end point on another selected figure is set as a referenced point. If the drag end point is not on another selected figure, the association operation is invalidated.
[0059]
(F) When the referenced point is determined, the dependent point is determined from the positional relationship between the shape determining point in the figure and the referenced point, and the degree of dependence is calculated. Then, the referenced point information 16 is created and stored in the graphic information storage unit 13. In the referenced point information 16, position information of the referenced point, a dependent point, a degree of dependence, a type of reference, and the like are set, and a pointer to the shape determination point information 15 of the reference point is set. On the other hand, a pointer to the referenced point information 16 is set in the reference point shape determination point information 15.
[0060]
(G) Update the figure having the reference point so as to match the referenced point and redisplay.
FIG. 10 is an explanatory diagram of the graphic operation processing according to the embodiment of the present invention. The graphic operation processing means 18 shown in FIG. 1 executes an editing operation on a graphic having associated points by the processing (a) to (g) shown in FIG. This process is called and executed when a point on the graphic is operated by the mouse and when a related referenced point is moved by some operation.
[0061]
(A) Receive notification of a point movement on a graphic.
(B) The editing mode of the figure in which the point moves is determined by the edit mode such as rotation / deformation / similar deformation, the type of reference, or the positional relationship between the moving point and the binding point, and the movement / rotation / deformation / Perform figure editing processing such as similar deformation.
[0062]
(C) Redraw the updated graphic on the display device 11.
(D) The graphic information storage unit 13 is searched to determine whether or not the updated graphic includes the referenced point information 16. If there is no referenced point information 16, the process is terminated.
[0063]
(E) If the referenced point information 16 exists, a new position of the referenced point is calculated from the degree of dependence on another point. The referenced point depends on three points a, b, and c, and the degree of dependence on each point is k_a, K_b, K_c, The new coordinates (x_p, Y_p)
x_p= X_ak_a+ X_bk_b+ X_ck_c
y_p= Y_ak_a+ Y_bk_b+ Y_ck_c
Is calculated. Note that (x_a, Y_a), (X_b, Y_b), (X_c, Y_c) Are the coordinates of points a, b, and c after the graphic update.
[0064]
(F) Based on the difference between the old coordinates and the new coordinates of the referenced point, the movement amount of the reference point according to the type of reference is calculated, and the movement of the point is notified. That is, the editing operation of the figure having the reference point that refers to the referenced point is recursively executed.
[0065]
(G) If there is a next reference point, the processing (e) and (f) are similarly repeated.
As is clear from the description of the present embodiment, the present system can be realized by a processing mechanism using ordinary sequential processing. For example, the shape determination point information 15 and the like are configured as an object including an operation procedure and an internal state value. , Can be realized by an object-oriented processing mechanism that advances processing by message passing. In this case, it is possible to simplify the processing configuration particularly regarding the reference / reference relationship.
[0066]
The reference / reference relationship between the figures can be canceled by a relationship canceling operation. When the relation canceling operation is performed, the referenced point information 16 is deleted and treated as independent figures.
[0067]
FIG. 11 is a diagram illustrating an example of a hardware configuration used in the embodiment of the present invention.
The present invention can be implemented by a known hardware mechanism as shown in FIG. 11, for example. The display adapter 103, the random access memory (RAM) 105, the CPU 106, and the disk adapter 108 are connected to the system bus 107. A graphic display 100, a keyboard 101, a mouse 102, and a video memory (VRAM) 104 are connected to the display adapter 103, and the contents of the VRAM 104 are displayed on the graphic display 100 via the display adapter 103. A disk storage device 109 such as a magnetic disk is connected to the disk adapter 108, and the disk adapter 108 controls data transfer between the RAM 105 and the disk storage device 109 according to input / output instructions of the CPU 106.

【The invention's effect】
As described above, according to the present invention, a group of figures having a certain relation can be collectively handled as a part, including their positional relations, and a graphic group corresponding to each of the related graphic elements can be handled. By the editing operation, it becomes possible to automatically edit related graphics according to the type of association without inconsistency. In particular, in the case of moving image editing such as animation, grouping a plurality of figures by the conventional method would fix the entire figure, but according to the association of figures according to the present invention, individual graphic elements were deformed. In addition, since the portion affected by the deformation can be automatically followed, the editing operation becomes extremely easy.
