2. Description of the Related Art In recent years, with the development of computers, various operations using computers have been performed not only at work but also at home. Also, with the development of hardware and software, it has become possible to create animations (moving images) using a computer even at an individual level.

Conventionally, there are the following methods for creating an animation. A method of creating data (two-dimensional bitmap data) for each frame and displaying each frame in order. This method is mainly used for creating a two-dimensional animation. A method of preparing an operation statement that describes an object and a series of operations of the object. The motion command is, for example, “walk right”, and the motion of the object is set in advance according to each motion command.

[0004] A method in which a three-dimensional model is prepared as an object, and a temporal change of each part of the three-dimensional model is designated by a mouse. The three-dimensional model is represented by, for example, points corresponding to human joints and a line connecting the points. By changing the position of each point over time, a motion is given to the three-dimensional model. Can be.

[0005]

However, in the method described above, when a long-time animation is created, a large number of two-dimensional bitmap data must be created, which requires much time and labor. For this reason, it is extremely difficult for an individual to create a long-time animation by the above method.

In the method described above, animation can be relatively easily realized because only an operation command is selected. However, since a series of actions is defined by one action command statement, the degree of freedom is low and the object cannot perform various actions. In the method,
Although it is possible to create animations with a high degree of freedom,
It is necessary to specify the change of each part of the dimensional model with time, which is complicated. Moreover, it takes time and tired eyes to specify the change of each part by the operator (mouse).
There is a problem that the arm hurts.

Accordingly, an object of the present invention is to provide an animation creation method, an animation creation apparatus, and a storage medium storing a program thereof, which can easily create an animation and have a high degree of freedom.

[0008]

The object of the present invention is to provide an animation creating method for operating an object on a display screen, wherein at least one verb and at least one adjective are combined to create an operation command,
The problem is solved by an animation creating method characterized by operating the object in accordance with the operation command.

Solved by features and storage media.

The operation of the present invention will be described below. In the present invention, an operation statement is created by a combination of a verb and an adjective. Here, the verb is a part (word) that determines the action of the object, and the adjective is a part (word) that describes the details of the action. For example, it is assumed that “walk” and “run” are set as verbs, and “right” and “left” are set as adjectives. in this case,
The user selects either “walk” or “run” as a verb, and selects one of “to the right” or “to the left” as an adjective to create an operation command sentence. At this time, the user can create four types of operation commands by selecting a verb and an adjective once.
Furthermore, if any one of "fast", "slow" or "normally" is selected as an adjective, twelve types of operation command statements can be created simply by selecting one verb and two adjectives. be able to.

As described above, in the present invention, since an operation instruction is created by combining a verb and an adjective,
The content of the operation can be set in detail, and various animations can be created. Further, by adding a parameter to a verb or adjective and changing the parameter, the operation can be described in more detail. For example, when rotating an object to the right, a parameter is added to the adjective “to the right”, and the rotation angle can be set in detail by the value of the parameter. As a result, it is possible to create an animation with a higher degree of freedom.
