Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selection control method for supporting a selection operation of an operation target object in response to a user operation event such as a mouse click operation of an object displayed on a display device screen by a computer program. .

[0002]

2. Description of the Related Art In a computer graphics application for manipulating a shape object, usually,
Specify the object to be operated by mouse operation. FIG. 20 is a diagram showing an example of display of objects in a two-dimensional / three-dimensional graphics application for explaining a conventional selection operation, and FIG.
Is a 3D graphics application
Cube object 2001 is a sphere object 2002
And if both are opaque, 2
This indicates a state where only 001 can be seen.
Also, FIG. 11B shows that in the two-dimensional graphics application, the text object 2004 is a color mount part object 2003 having a size smaller than its own.
And the character "ABCD" appears to be written on a colored background, and FIG. 3C is a three-dimensional view of the character.

In such an example, a sphere object 2
When 002 is to be selected as the operation target, the sphere object 2002 cannot be selected as long as the cubic object 2001 is opaque because the sphere object 2002 is hidden in the cubic object 2001. Also, in order to change the background color of the text object 2004, the color mount part object 200
3 is selected, the color mount part object 20
Since the text object 2004 having a size larger than the user's own is overlapped on 03, the color mount part object 2003 cannot be selected.

Therefore, conventionally, when changing the color of the color mount part object 2003, first, the text object 2004 is changed to the color mount part object 2003.
Has been moved to a position where a part of the color mount part can be seen, and then the operation of selecting the color mount part object 2003 has been performed. Then, after performing an operation of selecting a target object, a procedure of restoring the moved or changed overlapping order for visualization before selection to the original state is required.

[0005]

As described above, in the conventional selection operation of an object, the movement of the physical position and the arrangement state of another object are temporarily changed until the target object is selected. A situation in which an operation is required often occurs, and the operation until the target object is selected becomes extremely complicated, resulting in a problem that the work efficiency is reduced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a user with an intention to prepare for an original operation of "selection of an operation target object" without changing the physical position and arrangement state of a target object group. An object of the present invention is to provide an object selection control method capable of realizing a user interface for easily and surely selecting an object.

[0007]

To achieve the above object, the present invention provides an object selection control method for supporting a selection operation of a two-dimensional or three-dimensional object displayed on a display device.

[0008]

Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is an overall configuration diagram showing an embodiment of a system to which the present invention is applied.
In this embodiment, the present invention is applied to a system for displaying a three-dimensional object as shown in FIG. 20A, and can be similarly applied to a two-dimensional object. In FIG. 1, reference numeral 100 denotes a computer that performs processing for realizing the object selection control method according to the present invention. The computer 100 includes a keyboard 10
1, display 102, CPU 103, mouse 10
4, a program memory 105 and a data memory 106. Program memory 105 of computer 100
In this method, an operating system 105a for controlling the entire computer and an event such as a mouse operation by a user are delivered to each three-dimensional object, and a three-dimensional object to be selected is selected based on a response based on the response. Further, when there are a plurality of three-dimensional objects to be selected, the event dispatcher 105b for displaying selection support information for facilitating the selection and the various three-dimensional objects 106a to 106c stored in the data memory 106 Corresponding three-dimensional object (1) programs 105c to (n) 105e
Is stored.

The three-dimensional object i (i = 1 to n) programs 105c to 105e are programs for executing functions defined for each of the three-dimensional objects corresponding to the program. The program for controlling the behavior and appearance of the three-dimensional objects (1) to (3) when the viewing direction is changed is a three-dimensional object i.
(I = 1 to n) are implemented as programs different from the program, but are not shown because they are not directly related to the present invention.

The data memory 106 has a three-dimensional object (1) 106a and a three-dimensional object (2) 106
b, various three-dimensional objects (n) 106c
A dimensional object group is stored. As shown in FIG. 2A, these three-dimensional object groups include color, transparency, coordinate transformation matrix, and shape data as common attribute items 201. Further, as shown in FIG. To
Other functions such as getColor for acquiring color data of each object are held for each object.

The color data is composed of R, G, B values, and the transparency data is composed of step values from 0 (transparent) to 255 (opaque). The coordinate conversion matrix is composed of determinant data for converting coordinate data expressed in the local coordinate system into coordinate data in the world coordinate system.
Further, the shape data is constituted by coordinate data (local coordinate system or world coordinate system) of each vertex of the three-dimensional object. When a three-dimensional object having a curved surface portion such as a cylinder is generated by polygonal approximation, the three-dimensional object is configured by the respective vertex coordinate data.

The local coordinate system is a coordinate system that independently represents the shape of the three-dimensional object 301 as shown in an explanatory diagram of FIG. 3, and the world coordinate system is a three-dimensional space in which the three-dimensional object 301 is arranged. Is a coordinate system that defines The three-dimensional object 301 placed in the three-dimensional space defined by the world coordinate system is converted into a two-dimensional figure by projection and displayed on the display device screen. It is the projection plane coordinate system that defines the projection plane that projects the three-dimensional object 301 arranged in the world coordinate system. The three-dimensional object (two-dimensional projection image) projected on the projection plane has the gazing point as the origin, It changes according to the support axis direction in the viewpoint coordinate system with the Z axis as the support axis direction.

When the three-dimensional object 301 is displayed on the display device screen, a visual field viewed from the viewpoint is set.
The range seen from the viewpoint on the near side of the projection plane is set by the position of the front plane, and the range seen in the depth direction is set by the position of the back plane. The quadrangular pyramid-shaped three-dimensional space between the front plane and the rear plane is the view volume of the three-dimensional object. In the embodiment according to the present invention, as shown in FIG. 3, the positions D1 and D2 of the projection plane and the rear plane are set based on the viewpoint position, and the three-dimensional object 3 defined in the local coordinate system is set.
01 is perspective-transformed to a two-dimensional projected image in the projection plane coordinate system on the world coordinate system and displayed on the projection plane.

The method of generating a three-dimensional object handled in the present embodiment and which object is extracted as a selection candidate when a mouse event occurs for the generated three-dimensional object are described in the applicant of the present invention. Are described in detail in Japanese Patent Application No. 2001-172416 filed earlier, so that the description of the generation method, the structure of the object, and the extraction processing of the selection candidates will be omitted.

FIG. 4 is a diagram showing examples of functions for supporting various selection operations executed by the event dispatcher 105b which performs main processing for realizing the object selection control method of the present invention. Are held in the holding areas 402 to 407 of the global memory area 401 of the system. In FIG. 4, a select function, a showCurrent function, and a highlight function are held as selection support functions. The select function is a function that determines one or a plurality of objects according to a user's designation operation as a selected object for a plurality of selection candidate objects. The showCurrent function is a function that defines the appearance (display mode) of an object (hereinafter, a current object) of interest as a selection candidate. The highlight function is a function for switching to highlight display in order to specify the current object. This highlight function is called and executed from the showCurrent function.

FIG. 5 shows an operating system 105.
9 is a flowchart illustrating a process of an event dispatcher 105b started from a. First, when the mouse event e occurs, as described in Japanese Patent Application No. 2001-172416, an object (selection candidate object) through which a straight line connecting the viewpoint and the mouse cursor position passes is selected by the selection candidate object group acquisition processing. Extract
(Step 501). Next, all visible selection candidate objects are switched to translucent display (step 50).
2). Thereby, all objects hidden by other objects are also specified.

Next, a select function is executed to determine a final selected object from the selection candidate object group (step 503). In determining this, showCurrent
A user interface is provided that allows a target object to be easily selected by a function or the like. This will be described later. Next, when the object to be selected is determined, the translucent display of all the selection candidate objects performed in step 502 is canceled (step 5).
04), the process ends (step 505).

FIG. 6 is a flowchart showing details of the selection candidate object group acquisition process (step 501). First, the selection candidate object group holding area 405 provided in the global memory area 401 of FIG. 4 is emptied (step 601). And steps 602 and 60
The process formed in step 6, that is, a report is requested as to whether or not a straight line connecting the viewpoint and the cursor position is transparent to the object for all objects displayed on the screen. This is performed by instructing each object to execute a selection candidate object acquisition function (step 603).

The event dispatcher 105b checks the response from each object that has executed the selection candidate object group acquisition function for the own object (step 604), and indicates that a straight line connecting the viewpoint and the cursor position is transparent to the own object. Are added to the selection candidate object group holding area 405 (step 605). Finally, a sorting process is performed to sort the objects of the selection candidate group held in the selection candidate object group holding area 405 from those closest to the viewpoint (step 607), and the result is set as a selection candidate object group.

FIGS. 7A and 7B are diagrams showing an example of a state in which a plurality of selection candidate objects exist. FIG. 7A is a display example of a three-dimensional object, and FIG. 7B is a display example of a two-dimensional object. FIG. 7A shows an example in which a cylindrical object 702 exists inside a cubic object 701, and a spherical object 703 exists inside the same. In the state of FIG. 7B, the elliptical object 7 is placed on the outer rectangular object 711.
12 is on, and the inner rectangular object 713 is on it.

FIG. 8 is a diagram showing the state of each object viewed from above in order to clarify the positional relationship of each object in the depth direction of FIG. In such an example, when it is desired to select the cylindrical object 702 or the elliptical object 712 located second from the front, first, at the position indicated by P1 in FIG. 7A or P1 in FIG. Generate a mouse event e. Then, each object 701 to 703 or 711 to 713 in FIG. 7A is acquired as a selection candidate object group in the selection candidate object group acquisition processing in FIG.

Next, in the process of step 502 in FIG. 5, all of the selection candidate objects are made semi-transparent. As a result, even if the cube object 701 is opaque, the columnar object 702 hidden inside the cube object 701 becomes visible. Furthermore, even if the cylindrical object 702 is opaque,
The spherical object 703 hidden inside the cylindrical object 702 is also visible. Similarly, even if the rectangular object 713 is opaque, the elliptical object 712 hidden inside the rectangular object 713 becomes visible.

In this state, a list of selection candidate objects is displayed by performing the process in step 503 of FIG. This list display mode will be described later. Therefore, when one of the selection candidate objects displayed in the list is selected by a mouse button operation, the selected object is determined as an object intended by the user. After being determined as an object to be selected, all of the semi-transparent objects are returned to the display with the unique transparency by the processing of step 504 in FIG.
