Description

Drawing device

The present invention relates to a drawing device that manages a display list in a tree structure.

In many drawing processing systems (for example, OpenGL (registered trademark) and Adobe Flash (registered trademark)), drawing objects and drawing commands are stored in a data structure called a display list, and drawing processing is executed collectively. A function for realizing high-speed processing is provided. Among them, in the two-dimensional drawing processing system, there are many processing systems that manage the display list in a tree structure (for example, Adobe Flash), and the overlapping order of drawing objects is controlled by this tree structure.

FIG. 8 shows an example of managing drawing objects in a tree structure. In this figure, a rounded rectangle, a triangle, and a rectangle are managed on the tree 801. If the left side of the tree 801 is set to the back and the right side to the front, the drawing result 802 is obtained. ing.
Here, when creating a drawing program, this tree structure is operated so that drawing objects are arranged in a desired overlapping order via an API (Application Programming Interface) of a drawing processing system such as Adobe Flash. . In addition, each drawing object has a restriction that it can exist only in one place in the tree due to the structure of the display list. Therefore, the program creator must understand the tree structure and its restrictions and create the program while taking into consideration.

For example, conventionally, Patent Document 1 discloses the control of the overlapping order of drawing objects. Patent Documents 2 to 4 disclose techniques related to speeding up drawing by taking advantage of the fact that the display list manages drawing objects in a tree structure.

However, the conventional apparatus as described in Patent Document 1 is not conscious of the tree structure of the display list. In addition, in the conventional techniques described in Patent Documents 2 to 4, a drawing speed-up technique that makes use of the characteristics of the tree structure is provided, but for the convenience of controlling the overlapping order in the tree structure, a certain drawing object is provided. It is very difficult to place drawing objects that move in the middle of different subtrees in the tree structure.

For example, in FIG. 9, a tree structure 901 is formed in which triangles and rectangles are arranged according to a rule, and each set forms a subtree. In this state, when it is desired to add a drawing object 903 to which a motion animation that passes between a quadrangle and a triangle is applied as in the drawing result 902, considering the overlapping order control by the tree structure, the drawing object in the tree structure It is difficult to easily determine where to place 904, and it is difficult to implement a desired operation. If the drawing object 904 is placed between the triangle A and the quadrangle A, there is no problem when the drawing object 904 is placed in the subtree, but the drawing object 904 is placed in the subtree including the drawing object B. When moved, a drawing object is displayed behind the triangle B and the rectangle B, and a desired result cannot be obtained. Similarly, it is conceivable to place the drawing object 904 in the sub-tree of B. At that time, however, the drawing object 904 is always displayed in front of the triangle A and the rectangle A, and the desired result cannot be obtained.

The present invention has been made to solve such a problem, and an object thereof is to obtain a drawing apparatus capable of expressing freely.

A drawing apparatus according to the present invention includes a drawing processing unit that processes drawing data in a two-dimensional drawing coordinate system using a plurality of containers that can be operated by unifying the same drawing object, and the drawing processing unit processes drawing data. When clipping, the clipping processing unit that performs clipping processing on the same drawing object in each container area of multiple containers, and multiple containers that have been subjected to clipping processing are placed on the drawing data processed by the drawing processing unit And a drawing execution unit for drawing.

The drawing apparatus according to the present invention uses a plurality of containers that can be operated by unifying the same drawing objects, and arranges the drawing objects in these containers by clipping processing. Thereby, it is possible to obtain a drawing apparatus capable of expressing freely.

Hereinafter, in order to explain the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
FIG. 1 is a configuration diagram of a drawing apparatus according to the present embodiment.
As illustrated, the drawing apparatus according to the present embodiment includes a drawing processing unit 1, a clipping processing unit 2, and a drawing execution unit 3. The drawing processing unit 1 is a processing unit that processes the drawing data 5 of the two-dimensional drawing coordinate system using the drawing object container 4 and passes the processing result to the drawing execution unit 3, and is configured using a drawing processing system API. Has been. The drawing object container 4 is a container that can be operated by unifying copies of the same drawing object, and a plurality of drawing object containers 4 are provided. The clipping processing unit 2 is a processing unit for clipping a copy in the drawing object container 4 when the drawing processing unit 1 performs drawing data processing. The drawing execution unit 3 is a processing unit that arranges and draws a plurality of drawing object containers 4 subjected to clipping processing by the clipping processing unit 2 with respect to the drawing data processed by the drawing processing unit 1.

FIG. 2 is a hardware configuration diagram for realizing the drawing apparatus according to the first embodiment.
This configuration example includes a computer 10, an input device 20, and an output device 30. The computer 10 is composed of, for example, a personal computer and includes a processing device 11 and a storage device 12. The processing device 11 is composed mainly of a CPU (central processing unit), and the storage device 12 is composed of a ROM, a RAM, or a hard disk device. The input device 20 is a device such as a keyboard or a mouse for a user to perform an input operation, and the output device 30 is a device such as a display or a printer that outputs a processing result of the computer 10. 1 is stored in the storage device 12, and the drawing processing unit 1, the clipping processing unit 2, and the drawing execution unit 3 store software corresponding to the respective functions in the storage device 12. Is realized by the processing device 11 executing.

The drawing apparatus according to the present embodiment provides a special container for defining a drawing object that moves in the middle of different subtrees in the situation shown in FIG. This special container is the drawing object container 4, and this drawing object container 4 can be placed in any part of each sub-tree, and each drawing object container 4 operates in cooperation, so that the drawing object shown in FIG. A motion animation such as 903 can be realized. Hereinafter, such an operation will be described in detail.

FIG. 3 is an explanatory diagram illustrating the operation of the drawing apparatus according to the first embodiment. FIG. 4 is an explanatory diagram showing the flow of processing of the drawing object container 4.
In the drawing apparatus according to the present embodiment, it is assumed that the drawing object container 4 can be arranged at an arbitrary position in each subtree as in the tree structure 301. In FIG. 3, the dotted rounded rectangle represents the drawing object container 4, which is the drawing object 302 in FIG. 3. In this state, the same parts correspond to the drawing object container 4 (the drawing object 411 in FIG. 4), but each actually has a copy of the same part (the drawing object 412 in FIG. 4). All the copies can be operated in a unified manner (state 401 in FIG. 4). Here, being able to operate uniformly refers to, for example, that position control and size control during animation are performed at the same time, and may be other operations as long as they are operations related to the drawing object. When displayed next, the internal components are clipped and displayed by the drawing object container 4 at the boundary of each drawing object container 4 (state 402 in FIG. 4). Finally, by displaying the drawing object containers 4 side by side, it is possible to make it appear as if a single part exists (state 403 in FIG. 4). Here, for the sake of simplicity, the drawing object containers 4 are displayed in a horizontal direction without leaving a gap, but there may be a gap of any size between the drawing object containers 4. The arrangement is not required to be aligned and may be any arrangement. By arranging the drawing object container 4 to be processed in this manner as in the tree structure 301, it is possible to arrange a drawing object 303 that passes between drawing objects arranged in different subtrees, such as a drawing result 304. it can.

FIG. 5 is a flowchart illustrating the operation of the drawing apparatus according to the first embodiment.
The drawing processing unit 1 arranges the drawing object container 4 for the drawing data 5 as shown in the tree structure 301 of FIG. 3 and performs data processing (step ST1). Further, the clipping processor 2 performs a clipping process as shown in the state 402 of FIG. 4 (step ST2). As a result, the drawing execution unit 3 connects and displays the drawing object containers 4 as shown in a state 403 in FIG. 4 (step ST3), and obtains a drawing result 304 in FIG.

In the above description, one type of copy is included in one drawing object container 4, but a plurality of types of copies may be included.
When the copy included in the drawing object container 4 is outside the area of the drawing object container 4, the drawing execution unit 3 may speed up the drawing process by omitting the drawing process itself of the drawing object container 4. .

As described above, in the drawing apparatus of the first embodiment, by using the special container called the drawing object container 4, it is possible to easily realize drawing that passes through each drawing object between the sub-trees of the tree structure of the display list. it can. Further, considering that the clipping process in the state 402 is generally a drawing process that is processed at high speed and that the drawing process by the drawing execution unit 3 can be accelerated, the present invention is not used. Compared with, the processing load is not so large.

As described above, according to the drawing apparatus of the first embodiment, the drawing processing unit that processes the drawing data of the two-dimensional drawing coordinate system using the plurality of containers that can be operated by unifying the same drawing object. When the drawing processing unit processes drawing data, the clipping processing unit for clipping the same drawing object occupying the area of each container of multiple containers, and clipping for the drawing data processed by the drawing processing unit Since it has a drawing execution unit that places a plurality of processed containers and draws, it can draw so that there is a single part that can be observed only from the area occupied by the plurality of containers, Free expression is possible.

Further, according to the drawing apparatus of the first embodiment, the drawing processing unit manages drawing objects in a tree structure and arranges each container of a plurality of containers at an arbitrary position in a sub-tree of the tree structure. For example, it is possible to perform a free expression that is not bound by the constraints of the tree structure, such as drawing a drawing object that passes between other drawing objects across subtrees.

Further, according to the drawing apparatus of the first embodiment, each container of a plurality of containers is operated by unifying a plurality of the same drawing objects, so that more free expression can be made possible.

Further, according to the drawing apparatus of the first embodiment, the drawing execution unit is configured to omit the drawing process of the container when the same drawing object is located outside the container area, so that the drawing process can be speeded up. Can do.

Embodiment 2. FIG.
In the first embodiment, an example of a general use as a drawing apparatus has been described. In the second embodiment, an example in which the drawing apparatus of the present invention is applied to a list part on a Graphic User Interface (GUI) will be described. The configuration of the drawing apparatus in the second embodiment is the same as that of the first embodiment shown in FIG.

FIG. 6 shows a list part on the GUI, and each item of the list 601 includes a character string (for example, part 602) and a background pattern (for example, part 603). Further, this list 601 has a function of indicating an item selected in the list by a gray cursor 604, and the cursor 604 is smoothly animated by a cursor key operation or the like (animation like state 611 → 612 → 613). ). Here, for the sake of design, the cursor 604 is moved so as to pass between the character string of each item and the background pattern. That is, the cursor 604 is a drawing object that passes between a plurality of drawing objects in each subtree.

Also, the third item 605 (CCCC display item) is displayed lightly, which indicates that the item is in an invalid state. In this case, the cursor 604 passes further forward than the character string. (Animation like state 614 → 615 → 616). That is, the position where the cursor 604 slips through in the sub-tree is different between the item 605 and other items.

When trying to realize such a list of designs, as described above, it is very difficult to realize with a conventional technique. Therefore, the drawing object container 4 which is a special container of the drawing apparatus of the present invention is arranged in each sub-tree, and the position of the special container is usually placed between the character string and the background pattern and in front of the character string when it becomes invalid. By setting, a desired appearance can be realized.

FIG. 7 shows a tree structure 701 of the display list at this time. As in FIG. 3, the drawing object container 4 is indicated by a dotted rounded rectangle. As shown in FIG. 7, in the

subtrees

702, 703, 705, 706, and 707, the cursor 604 (see FIG. 6) must pass between the character string and the background pattern, so the drawing object container 4 is on the tree structure 701. It is arranged at an intermediate position. On the other hand, in the sub-tree 704, the item 605 is in an invalid state, and the cursor 604 needs to pass through the character string, so that the drawing object container 4 is arranged at the right position (front position) on the tree structure 701. Yes.

Further, when the invalid state is switched due to some trigger, the drawing processing unit 1 may change the position of the drawing object container 4 on the tree structure 701.

As described above, even in a design in which the drawing object passes through different positions for each sub-tree, desired drawing can be easily realized by appropriately setting the position where the drawing object container 4 is placed. Further, by changing the position of the drawing object container 4 in the sub-tree, it is possible to easily change how the drawing object slips through dynamically.

As described above, according to the drawing apparatus of the second embodiment, the drawing processing unit dynamically changes the position of each container in the subtree, and therefore dynamically changes the display contents. Can do.

In the present invention, within the scope of the invention, any combination of the embodiments, or any modification of any component in each embodiment, or omission of any component in each embodiment is possible. .

As described above, the drawing apparatus according to the present invention relates to a configuration for managing a display list in a tree structure and managing an overlapping order of drawing objects, and overlapping between objects belonging to the same subtree in a two-dimensional drawing processing system. Suitable for forward control.
