Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) The present invention relates to a graphic processing system capable of a plurality of input methods.

(Prior Art) Generally, a graphic processing system employs various input methods such as an on-screen menu selection as well as a keyboard.

The input command format has a hierarchical structure such as main command → subcommand → parameter as shown in FIG.

For example, for an instruction to draw a horizontal line, an instruction is executed from each hierarchy using a combination of define (line) -line (line) -horizontal (horizontal) instruction information.

By the way, the conventional graphic processing system is executed after being converted into information in a unique format for each input method. For this reason, if the input method is determined in the first layer, it is necessary that all subsequent layers adopt the same input method.

Therefore, an arbitrary input method cannot be adopted in an arbitrary hierarchy, and operability cannot be improved.

(Problems to be Solved by the Invention) As described above, in the conventional graphic processing system, each input method is converted into information in a unique format and executed, so that an arbitrary input method can be selected in an arbitrary hierarchy. Operability could not be improved.

The present invention has been made in view of the above points, and has as its object to provide a graphic processing system with excellent operability that can employ an arbitrary input method at any hierarchy.

[Configuration of the invention]

(Means for Solving the Problems) In order to achieve the above object, in the present invention, an input means determining means for determining an instruction input means in an instruction analysis storage means and an information converting means for converting coordinate information into character information are provided. Is provided.

(Operation) As a result, a command input by instructing display on the display device with the instruction device is converted from coordinate information into character information, so that an arbitrary input method can be adopted in an arbitrary hierarchy. The restriction of the method can be eliminated.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. 1 is a functional block diagram, including first, second and third command input means 1, 2, and 3 as command input means. Here, the first command input means 1 indicates an input by a keyboard. The second command input means 2 is, for example, as shown in FIG. 2, an input by an on-screen menu selection method in which the hierarchy to be inputted in the next step is indicated by moving the instruction device 6 as shown in FIG. is there.
Further, as shown in FIG. 3, the third command input means 3 is, for example, an on-screen tablet selection method of inputting a specific command displayed on the display device 5 by moving the pointing device 6.

An arithmetic unit 4 for performing calculations and controls is connected to each of the command input means 1, 2, and 3. The computing device 4 is further connected to a display device 5. The display device 5 also serves to display a figure to be drawn.

Further, the execution unit 4 is connected to the instruction execution determination means 7. The instruction execution determining means 7 includes an instruction analysis storing means 8, a table and an instruction executing means. Further, the instruction analysis storage means 8 includes an input means determination means 9 for determining an instruction input means, an information conversion means 10 for converting coordinate information into character information, an instruction storage means 11 for storing input instructions, and whether or not a stage to be executed. Storage unit 12 for converting character information into numerical information, and an instruction storage unit 14 for storing digitized instruction information.

The instruction analysis storage means 8 stores an on-screen menu table 15 for recognizing the correspondence between the coordinate information and the character information at the time of input by the on-screen menu selection method, and the correspondence between the coordinate information and the character information at the time of input by the on-screen tablet selection method. An on-screen tablet table 16 for correspondence recognition, a command storage table 17 for storing character information converted by the information conversion means 10, a command syntax table 18 for correspondence between character information and numerical information, and information obtained by analyzing instructions. The analysis result storage table 19 to be stored is connected. The analysis result storage table 19 is connected to a command execution module 20 for executing an instruction while referring to information in the table.

Next, the operation will be described with reference to the flowcharts shown in FIGS. 4 (A) and 4 (B). That is, the input method of the command input by the first, second or third command input means 1, 2, 3 is determined by the input means determination means 9.

If the result of this determination is a keyboard input, the input information is character information, so the command is stored in the command storage table 17 as character information by the instruction storage means 11.

If the determination result is an on-screen menu selection input, the input information is coordinate information. That is, the instruction input at this time is performed by selecting the on-screen menu displayed on the display device 5 with the instruction device 6, and thus becomes the coordinate information. The coordinate information is converted into character information by the information conversion means 10 with reference to the on-screen menu table 15 and stored in the command storage table 17 by the instruction storage means 11.

Similarly, when the determination result is an on-screen tablet selection input, the input information is coordinate information. That is, the instruction input at this time is performed by selecting the on-screen tablet menu displayed on the display device 5 with the instruction device 6, and thus becomes the coordinate information. Then, the coordinate information is converted into character information by the information conversion means 10 with reference to the on-screen tablet table 16 and is stored in the command storage means 11.
Is stored in the command accumulation table 17.

Thus, no matter what instruction is input, the input information is stored in the command storage table 17 as character information.

In addition, the storage state determination unit 12 determines whether the information stored in the command storage table 17 is a stage to be executed. Actually, information for recognizing the execution stage is input as input information. For example, a symbol / (slash) is input. Then, when it is determined that it is the execution stage, the information is transmitted to the instruction analysis means 13. Conversely, if it is determined that it is not the execution stage, it is necessary to input the next command information.

Further, the character information judged to be in the execution stage by the accumulation state judging means 12 is converted into numerical information by the instruction analyzing means 13 with reference to the command syntax table 18 and is analyzed by the instruction storing means 14 to store the analysis result storing table 19 Is stored in
In addition, the command syntax table 18 stores information such as the number of digitized points and the number of recognition elements required by the instruction, in addition to the numerical values corresponding to the character information, and these information are also added at the time of character information conversion. It becomes numerical information.

Then, the command execution module 20 refers to the information in the analysis result storage table 19, has a DigiTimes and element recognition by information input, and executes an instruction when conditions are satisfied.

Here, the operation will be described using a specific instruction of “perform R chamfering with a radius of 5”. This instruction is divided into the following layers: main command → subcommand → parameter → separation → data; define (execute) → fillet (R chamfer) → radius5 (radius 5) → / (separation) → element recognition. Then, the main command, the subcommand, and the parameter are sequentially input using, for example, an on-screen tablet selection, an on-screen menu selection, and a keyboard. All of this information is stored in the command storage table 17 as character information as described above. Next, when a break is input by selecting an on-screen menu, the accumulation state determination means 12 determines that the operation is in the execution stage. As a result, the character information is converted into numerical information by the instruction analysis means 13 and information such as the number of digitized points required by the instruction and the number of recognition elements required by the instruction is added, and stored in the analysis result storage table 19 by the instruction storage means. . And the command execution module 20
Refers to the numerical information stored in the analysis result storage table 19, has two inputs of element recognition, and performs R chamfering with a radius of 5 as shown in FIG.

In this embodiment, the input means judging means 9 judges what input method is used, and the information converting means 10 obtains information of a common method. As a result, an arbitrary input method can be adopted in any hierarchy, and operability can be improved.

〔The invention's effect〕

As described above, in the present invention, the input means of the command is determined by the input means determination means, and when the input is coordinate information, the information is converted into character information by the information conversion means.
By making the input common information, a graphic processing system excellent in operability can be provided.
