Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to various three-dimensional presentation systems.

[0002]

2. Description of the Related Art Conventionally, in a three-dimensional presentation such as a simulation in the field of architecture, the size of a space is expressed by expressing a human-sized human board as in a known example. In this example, the size and display position of the human are fixed, and the human model itself is not three-dimensional and lacks a sense of reality. Also, since the model does not work, it is only a static spatial representation. At present, in the game field, etc., there is a technology in which a three-dimensional human model operates on the screen according to the user's intention, but in the architectural field that requires sophisticated model data,
It was a representation of a static space due to problems such as hardware display performance.

[0003] However, considering the current technical level, it is a level at which a presentation including the operation of a model can be made even in a landscape simulation or the like in the architectural field.
Therefore, in the present invention, an operating model is expressed in a landscape simulation or the like, and a more realistic three-dimensional space can be expressed. Similar technologies are VR (Virtal Reality),
It is being realized in the field of simulation. Also, 3
In measuring the distance between any two points in a dimensional space, the distance can be measured in real time with a rubber band cursor or the like, as seen in three-dimensional CAD or the like. However, this method has an industrial image and has a sense of incongruity in presentations at houses and the like. In addition, since the display position of the measured value is generally located at one corner of the screen, it is necessary to move the viewpoint more than necessary, which is not always suitable for intuitive grasp of the distance.

[0004]

The present invention assists in grasping the size of a space by expressing a three-dimensional space and operating a human model in the three-dimensional space. In the present invention, when measuring the distance between any two points in a three-dimensional space, the human model actually moves or moves in the three-dimensional space with a measure, instead of the conventional method using a rubber band or the like. Measure the distance between any two points. At this time, the measure expands and contracts with the measurement operation, and the distance can be more intuitively grasped by displaying the measured value near the measure that expands and contracts. Therefore, even in a three-dimensional presentation of a house or the like, there is little discomfort and the presentation is not hindered.

[0005]

According to the present invention, in a presentation system or the like for expressing a model of a human or the like in a three-dimensional space, a human model is displayed and the size of the space is determined. An object of the present invention is to measure a distance between any two points in a three-dimensional space by providing a mechanism for generating an operation for measuring the distance and a mechanism for displaying a measurement result, and operating a human.

In the measuring operation, one end of the measuring instrument is fixed by determining the starting point of the object to be measured, and by operating the human model, the other is displayed as a line segment which expands and contracts with the starting point. At this time, by displaying the length of the line segment near the line segment, the user can measure the distance between any two points in the three-dimensional space.

An embodiment of the present invention will be described in detail with reference to FIGS. 2, 3, 4, 5, and 6. FIG.

1. Operation Editing Process The operation editing process 4 will be described in detail with reference to FIGS.

The operation editing processing 4 includes an operation schedule processing 11, an interference check processing 12, an operation synthesis and editing processing 13
And a composition ratio control 14.

(1) Operation Schedule Processing The flow of the operation schedule processing 11 will be described with reference to FIG.

The operation schedule processing 11 confirms the input of the operation instruction information transmitted from the input recognition processing 5 and determines the type of operation (17). Next, the presence or absence of an obstacle such as a space model is checked in the direction of the operation, and if there is an obstacle, an interference check process (18) is performed. If there is no interference, the type of operation is determined (20), and the combination ratio is determined (21), and the operation combination and editing processing is called (22).

(2) Interference Check Process In the interference check process 18, interference in a three-dimensional space is detected from information on the type of operation and the direction of the operation. At this time, the spatial model data is read, and the model and the model are interfered by a geometric operation in a three-dimensional space, and whether or not the interference is possible is reported. In the case of interference, avoidance action processing (19) is performed as necessary.

In case of interference, avoidance action processing (19)
Alternatively, alternative processing such as stopping the operation of the model may be considered, but whether to perform the avoidance action processing is determined based on the type of the corresponding application.

(3) Behavioral synthesis and editing processing In the behavioral synthesis and editing processing 13, the operation schedule processing 1
From 1, information on the type of motion, the direction of motion, the speed of motion, etc., is received, and motion data for operating the human model is selected. Here, for operations that can be generated by synthesizing data that is stationary and data that is walking, such as “start walking”, a smooth operation is synthesized and edited by controlling the synthesizing ratio of both data.
The synthesized and edited operation data is transferred to the display device 2, and the operation specified by the input is expressed on the screen.

2. Input recognition processing The input recognition processing 5 will be described with reference to FIG.

In recent presentations, it is required to be interactive (interactive), and the input device occupies an important position. Also in the present invention, it is required to be interactive, and it is possible to operate a human model as desired by a user in a three-dimensional space, and to express a real space. Although various input devices can be considered as the input device, a joystick will be described as an example here for convenience. The user looks at the three-dimensional space and the human model represented on the display device 2 while viewing the input device 3.
Operate the joystick.

For example, when the joystick is tilted to the right, an operation instruction 15 for walking the model in the right direction is input to the input recognition processing 5. By such an operation, the direction of walking can be instructed, but when used in combination with another input device such as a keyboard, the movement of the neck, the movement of the arm, and the like can be defined and input.

When designating the starting point of the object to be measured, the joystick is switched to the arm movement, and the joystick is operated to move the hand to the starting point of the object to be measured and to designate the starting point with a button or the like. I do. Subsequently, the joystick is operated by the same means, and the hand is moved to the end point of the measurement object. During this operation, a line segment is displayed between the starting point and the hand, expands and contracts with the operation, and furthermore, the length of the line segment is displayed near the line segment.

3. Behavioral synthesis and editing processing The behavioral synthesis and editing processing 13 will be described with reference to FIG.

In the action synthesizing / editing process 13, necessary action data 9 is read from the action data group 9 and synthesized according to the designated action. At this time, the synthesis ratio control 14 of the operation is performed. In the combination ratio control 14, the operations are combined according to the specified combination ratio. For example, when generating a “walking” motion, the “walking” motion and the “stationary” motion are read, and the composition is performed by increasing the “walking” component and decreasing the “still” component as the respective composition ratios. , "Walk out" action. The "stop" action can be generated by decreasing the "walking" component and increasing the "still" component. Similarly, it is possible to generate a motion having features such as “walking fine” and “walking cold”.

4. Measurement distance display processing The measurement operation and the measurement distance display processing will be described with reference to FIG.

The measurement operation generates an operation as part of the operation instructed from the input device, similarly to the above-described walking operation. In the measurement operation 27, first, the measurement operation position 27 of the measurement target 23 is designated, and then the arm 26 is moved to perform the measurement operation 27. Until the measurement end is instructed, a line segment is displayed linearly from the measurement start position 24 along with the measurement operation 27, and the length of the line segment is displayed near the line segment with the measured value 25.
