Abstract

PURPOSE:To obtain the dynamic plotting of a graphic and an image in a real time, by performing the designation of a new time by receiving the completion report of plotting for a plotting instruction issued to a plotter, and calculating the plotting attributes of all of the graphics and images to be targeted at a designated time. CONSTITUTION:It is assumed that the plotting of the graphics A and B at a time (t)=t0 are completed as shown in figure (a) and the completion report of the plotting is issued from the plotter 20. Firstly, a time designation part 14 reads out a present time t=t1 from a clock 11, and designates the time to calculate the next plotting attribute. A plotting attribute calculation part 15 reads data from an operating storage part 12, and calculates the plotting attributes of the graphics A and B at the time t=t1. In a latest plotting attribute storage part 13, the latest plotting attributes of the graphics A and B are stored. A plotting judging part 16 compares the plotting attributes stored in the above stated storage part 13 with those calculated at the calculation part 15, respectively, and issues the plotting instruction if at least one of them is changed.

Problems to be Solved by the Invention However, in the above configuration, drawing commands are forcibly sent to the drawing device at predetermined time intervals, so if drawing is performed in real time, the next drawing will be interrupted midway through drawing. There is a problem in that even if a command is issued or, conversely, drawing is completed, an extra waiting time is generated until the next drawing command is issued.

In view of this, an object of the present invention is to provide a graphic image dynamic drawing control device that can issue drawing commands in accordance with the drawing performance of a drawing device.

Means for Solving the Problems The present invention has a time designation unit that reads the current time from a clock and specifies the time, and stores data that describes the drawing attributes of each figure or image as a function of time. a drawing attribute calculation section that calculates a drawing attribute at the time specified in the time specifying section based on data read from the action storage section; and a latest drawing attribute storage that stores the latest drawing attribute. and when the drawing attribute calculated in the drawing attribute calculation section is different from the drawing attribute in the latest drawing attribute storage section, the latest drawing attribute is updated and a figure/image drawing command is sent to the drawing device. This graphic image dynamic drawing control device includes a drawing judgment unit and sequentially and repeatedly performs time designation, drawing attribute calculation for all figures and images, and drawing judgment upon receiving a drawing completion report from a drawing device.

Operation With the above-described configuration, the present invention specifies a new time upon receiving a drawing completion report for a drawing command issued from this device to a drawing device, and specifies the drawing attributes of all target figures/images at the specified time. After calculating and making drawing decisions, by sequentially and repeatedly issuing drawing commands to the drawing device, multiple figures and drawings can be drawn in real time.
It is possible to realize dynamic image drawing according to the performance of the drawing device.

A drawing judgment unit that issues a drawing command to the device, 17
Reference numeral 18 indicates a drawing command issued from the drawing determination unit 16, 18 indicates a drawing completion report issued from the drawing device, and 20 indicates the drawing device.

The operation of the graphic image dynamic drawing control device of this embodiment configured as described above will be described below with reference to FIG. As a specific example, a case will be described in which a figure B having three drawing attributes: X coordinate, y coordinate, and color is drawn.

FIG. 2 is an example in which the drawing attributes of a certain figure B are described as a function of time. a is a change in the X coordinate of figure B, b is a change in y coordinate of figure M, C is a change in color of figure M, d is a change in figure BOX coordinate, e is a change in y coordinate of figure B, f is figure It shows the change in color of B.

FIG. 3 shows the drawing state of figures M and B at a certain time. a is the drawing state at time 1=10, and b is the drawing state at time t=tl.

FIG. 4 shows the drawing attributes of figure B at a certain time. a is the drawing attribute at time t=to, and b is the drawing attribute at time 1=11.

Assume now that the drawing of the figure person B at time 1=1o has been completed and a drawing completion report has been issued from the drawing device as shown in FIG. 3a. The time advances from t=to by the time required to draw the figure man, B, and is now 1=11. First, the time specifying unit 14 reads the current time t==t from the clock 11 and specifies the time at which the next drawing attribute is to be calculated. The drawing attributes of the figure person B are described as a function of time as shown in FIG. 2, and are stored as data in the motion storage section 12. The drawing attribute calculation unit 16 reads data from the operation storage unit 12 and calculates the drawing attributes of figures M and B at time t=t1. The latest drawing attribute storage section 13 stores the latest drawing attribute of figure B, that is, the drawing attribute at time 1=10 as shown in FIG. 4a.

The drawing determination unit 16 compares the drawing attributes stored in the latest drawing attribute storage unit 13 and the drawing attributes calculated in the drawing attribute calculation unit 16 for each of figures M and B, and determines whether at least one of the three attributes is correct. If it has changed, the latest drawing attribute in the latest drawing attribute storage section 13 is updated and a drawing command 17 is issued to the drawing device 2o. That is, as shown in FIG. 4, the y-coordinate of the figure person and the color of the figure B are updated, and a drawing command 17 for both figures M and B is issued to the drawing device 20. The drawing device 2o returns a drawing completion report 18 to the drawing judgment unit 16 when it finishes drawing the figures M and B as shown in FIG. The drawing determination section 16 receives the drawing completion report 18 from the drawing device 2o and returns the process to the time specifying section 14. Processing after the time designation section 14 is repeated in the same manner as described above.

Note that the drawing attributes can include not only the X coordinate, y coordinate, and color as described in this embodiment, but also all attributes for drawing figures and images such as tilt, size, line type, and line width. .
