DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for displaying an instruction image for rotating and displaying a multidimensional display figure and a method for displaying a rotationally moving figure for a multidimensional display figure.

[0002]

2. Description of the Related Art Conventionally, for example, when designing an automobile, a simulation graphic is sometimes three-dimensionally expressed on a display screen by using computer graphic technology. In such a case, there has been proposed a configuration in which a graphic is subjected to coordinate transformation so that a state in which the three-dimensional display graphic is rotated and moved by a desired amount can be displayed.

In displaying such a rotationally moving figure of a three-dimensional display figure, a coordinate system representing an arrow direction is displayed on a screen in order to represent the direction from which the figure is viewed (see FIG. 15), and a numerical value representing the rotation angle is displayed on the screen (see FIGS. 16 and 17). As a method of rotating a figure, there are a dial device method and a pointer device method.

Here, the dial device system is shown in FIG.
As shown in FIG. 8, the display device 101 (this display device 101
Has a computer and a display) connected to a dial device (input device) 102.
By rotating a to 102c, the amount of rotation of the dial is replaced with an angle, and the figure is subjected to coordinate conversion according to the angle, and the three-dimensional display figure is rotated and moved by a desired amount.

At this time, the orientation of the three-dimensional shape during rotation is
It is represented by the "axis of the XYZ coordinate system" displayed on the screen. The outline is shown in FIGS. That is, assuming that the initial screen is in the state of the XZ plane as shown in FIG. 19, first, by turning the Z dial 102c, the figure is changed to the Z-axis as shown in FIG. Rotate around. By further turning the X dial 102a, the figure rotates around the X axis in conjunction with this, as shown in FIG. As a result, it is possible to display a figure obtained by obliquely viewing the original figure on the screen of the display.

FIG. 2 shows the pointer device method.
As shown in FIGS. 2 and 23, a pointer device 103 (pointer device 10) connected to a display device 101 (this display device 101 also has a computer and a display).
3 is an input device, and a tablet or a mouse is used. By operating the dial 101a or the scroll bar 101b displayed on the screen, the dial 101a or the scroll bar 101 is moved.
A method in which the movement amount of b is replaced with an angle, the figure is subjected to coordinate conversion in accordance with the angle, and the three-dimensional display figure is rotated and moved by a desired amount.

That is, the pointer device system is functionally similar to the dial device system. The difference lies in the input device, which uses a tablet or mouse instead of a dial. Then, in this case, the dials 101a and 101b are displayed on the screen,
By operating the pointer device 103 and operating the displayed dial 101a and scroll bar 101b, the three-dimensional display figure is rotated and moved by a desired amount.

[0008]

However, in such a conventional method, if the figure is continuously rotated, the direction of the arrow of the displayed figure cannot be intuitively understood, or the rotation of a plurality of coordinate axes cannot be performed at the same time. There is a problem that it is not possible to directly indicate the desired viewing direction with a device.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and it is possible to intuitively recognize the arrow direction of a displayed figure and to directly view the desired arrow direction with a device even when the figure is continuously rotated.

Is displayed on the screen 3A. The pointer position indicating means 11 is a pointer device 2
By operating the figure rotation button, a pointer marker 8 is displayed at a desired position of the instruction image 6 in accordance with the operation.

The pointer position detecting means 12 determines the position (X, Y, Z) on the screen 3 A indicated by the pointer device 2, that is, the desired position of the pointing image 6 indicated by the pointer marker 8. Is to be detected based on The rotation matrix calculation means 13 calculates X, Y,
A rotation angle about the X axis, Y axis, and Z axis is obtained from each Z position, and a rotation matrix for X, Y, and Z is calculated.

The rotational movement graphic display control means 14 multiplies the three-dimensional graphic before rotation by the rotational matrix for X, Y, and Z calculated by the rotation matrix calculating means 13 to obtain a graphic after rotation. The graphic is displayed on the screen 3A. With reference to FIGS. 4 and 5, a description will be given of a method of displaying a figure obtained by rotating and moving a three-dimensional display figure using the method of the present invention with the above-described configuration.

First, when the system is turned on, initial settings (creation of a frame for the instruction image 6, setting of the origin, creation of characters) are performed. Thereafter, when the figure rotation button of the pointer device 2 is pressed, the instruction image display control means 10 causes the instruction image 6 including the frame 4 and the character 5 to be displayed on the screen 3A (FIG. 4).
Step A1 and Steps B1 to B4 in FIG. 5).

Further, the pointer position indicating means 11 responds to the operation of the figure rotation button of the pointer device 2 by
The pointer marker 8 is displayed at a desired position of the instruction image 6 (step A2 in FIG. 4, steps B5 and B6 in FIG. 5).
At the same time, the pointer position detecting means 12 determines the position (X, Y, Z) on the screen pointed by the pointer device 2, that is, the desired position of the pointing image 6 pointed by the pointer marker 8 from the pointer position pointing means 11. (Step A3 in FIG. 4, Step B7 in FIG. 5).

Thereafter, the rotation matrix calculating means 13
Then, the rotation angles about the X-axis, Y-axis, and Z-axis are obtained from the X, Y, and Z positions, and the rotation matrix for X, Y, and Z is calculated (steps B8 to B10 in FIG. 5). That is, X,
From each of the Y and Z positions, the rotation angle is determined, and the arrow direction in which the pointer marker 8 is pointed is determined (step A in FIG. 4).
4).

Then, the rotational movement graphic display control means 14
, X obtained by the rotation matrix calculation means 13
A rotation matrix relating to Y and Z is multiplied by a three-dimensional figure before rotation to obtain a figure after rotation, and a frame 4 and a character 5 for associating a screen position and a display direction for displaying this figure on the screen 3A. Is displayed on the screen 3A (step A5 in FIG. 4 and step B in FIG. 5).
11, B12).

As a result, the rotationally moving graphic of the three-dimensional display graphic is displayed in a state of being superimposed on the instruction image 6, and
By looking at the position of the pointer marker 8 at this time, from the position of the pointing image 6 where the pointer marker 8 is located, it is immediately apparent from which arrow direction the rotated figure is viewed. As a result, the direction of the arrow to be viewed can be directly specified by the pointer device 2, thereby making it possible to easily perform the instruction and intuitively grasping the display direction (the direction of the figure) when the figure is rotated. Can be.

When the figure rotating operation is completed, the frame 4
The instruction image 6 including the characters 5 and 5 is set in a non-display state (step A7 in FIG. 4 and step B13 in FIG. 5). Next, an actual example of a simulation three-dimensional figure of an automobile body will be described. First, assuming that the original graphic 7 is a left side view as shown in FIG. 6, if the pointer marker 8 is moved to the position of FIG. A figure 7 '(the figure 7' is a view of the vehicle body viewed obliquely from above) after the rotational movement as shown in FIG. 7 is performed by continuously performing combined rotation to the side and front states. 6 is displayed in a state of being superimposed.

Assuming that the original figure 7 is a left side view as shown in FIG. 6, if the pointer marker 8 is moved to the position shown in FIG.
The original figure continuously undergoes combined rotation from the left side state to the plane state side and back side state (in this case, the degree of rotation to the back side state is larger, as can be seen from the position of the pointer marker 8). 8, the figure 7 '' after the rotational movement as shown in FIG. 8 (this figure 7 '' is a view of the vehicle body viewed obliquely from the rear slightly above) is displayed in a state of being superimposed on the instruction image 6.

Further, assuming that the original figure 7 is a left side view as shown in FIG. 6, if the pointer marker 8 is moved to the position of FIG. From the bottom to the front side and the front side, the figure 7 '''after the rotational movement as shown in FIG. 9 (this figure 7''' ) Are displayed in a state of being superimposed on the instruction image 6.

Of course, the pointer marker 8 can be set at an arbitrary position on the instruction image 6 by an instruction from the pointer device 2. It goes without saying that the original figure can be rotated and moved to the position determined by. Note that the simulation three-dimensional figures 7, 7 ', 7 ", 7"'
Is superimposed on the instruction image 6, the thickness of the line of the instruction image 6 can be set to be thin. In this case, the instruction image 6 is displayed as the simulation three-dimensional figures 7, 7 ',
7 ", 7""are not obstructed, and the desired figure 7, 7", 7 ", 7""can be displayed in an easily viewable state.

As shown in FIG. 10, a scale and a number representing the amount of rotational movement of the three-dimensional display figure can be displayed on the frame 4. In this way, the amount of rotational movement of the three-dimensional display figure can be accurately grasped, not the amount of eye. Further, as shown in FIG. 11, the frame line 4 can be displayed by a dotted line instead of a solid line. Of course, other than the dotted line, although not shown, the frame line 4 can be displayed by a chain line, a broken line, or the like.

Further, on the display screen 3A, a figure capable of imagining the frame 4 is displayed, and a rotational movement display is performed in the vicinity of the virtual line of the frame 4 imagined from the figure imaginable for the frame 4. It is also possible to display a character indicating the display direction of the three-dimensional display graphic to be performed. Specifically, as shown in FIG. 12, a cross display 4a, a T-shaped display 4b, and an angle display 4c are provided at the intersection of the frame lines, and as shown in FIG. 4d.

Of course, graduations and numbers indicating the amount of rotational movement of the three-dimensional display graphic as shown in FIG. 10 can be displayed on the instruction image 6 shown in FIGS. further,
An example in which a character is displayed near the virtual line of the frame line 4 or a virtual line of the frame line 4 imagined from the figure that can virtualize the frame line 4 as an indication of the display direction of the three-dimensional display graphic to be rotated and displayed. But also other figures, symbols or characters, figures,
A combination of symbols (mark information) can also be displayed.

In the above example, the frame 4 or the frame 4
An example is shown in which mark information such as characters indicating the display direction of a three-dimensional display graphic to be rotated and displayed is displayed along the vicinity of a virtual line of a frame line 4 imagined from a figure that can be virtualized. However, the mark information may be in the vicinity of the imaginary line of the frame line 4 or a virtual line of the frame line 4 imagined from the figure capable of imagining the frame line 4, and there is no need to follow these. That is, for example, in the vicinity, mark information such as characters may be displayed in a state where the mark information intersects with the frame line or the virtual line.

Further, as shown in FIG. 14, the simulation three-dimensional figure 7 (7 ', 7 ", 7"') and the instruction image 6 can be displayed so as not to overlap on the screen 3A. This makes the display easier to see. In addition,
In the above embodiment, a display example of a three-dimensional graphic is shown, but the idea of the present invention can be applied to a display of a multidimensional graphic.
