More specifically, even if the number of characters increases in the virtual space, the computational cost increases rapidly. The present invention relates to a virtual character adjustment behavior display method and apparatus using a 2D texture-based induction field that can solve the problem of real-time simulation, and a virtual ecological park visualization system using the same.

Recently, with the change of leisure life, interest in nature-friendly ecosystem theme parks has been greatly increased. In contrast, the contents of the experience halls in most theme parks in Korea provide content through simple audiovisual pictures or videos. Providing realistic and realistic contents is a very important factor in order to improve this and induce interest as well as maximize the effect of education and promotion. However, the reality is still lacking.

On the other hand, researches on realistically expressing the movement of autonomous agent-based animals or insects have been conducted in the last decade [Craig W. Reynolds., Flocks, herds, and schools: A distributed behavioral model., ACM Computer Graphics, 21 (4): 25-34, 1987., X. Jin, J. Xu, CCL Wang, S. Huang, and J. Zhang, interactive control of large crowd navigation in virtual environment using vector field, "in IEEE Computer Graphics and Application, vol. 28, no. 6, 2008, pp. 37-46., S. Patil, JPVD Berg, S. Curtis, MC Lin, and D. Manocha, "Directing Crowd Simulations Using Navigation Fields" , presented at IEEE Trans.Vis.Comput.Graph., 2011, pp. 244-254.

However, most autonomous agent-based systems proposed in the related art assume that each agent is an independent decision entity. Decisions on agent movements also focus on rules and small group behaviors expressed in complex formulas. Problems with these approaches represent behavior in very small areas where interactions with other agents and environments are not at the local level or often desired. In other words, in the multi-agent simulation system, agents perform collision avoidance and various control actions through interaction between agents and agents. As a result, it is often difficult to produce desirable behavior in group behavior or behavior patterns. In addition, when the interaction range is expanded or the number of individuals is increased, the computational cost for the interaction is rapidly increased, making it difficult to perform real-time simulation.

Therefore, the present invention has been proposed to improve such a conventional problem, a new type of 2D texture-based induction field that can solve the problem that the calculation cost increases rapidly even if the number of characters in the virtual space is not increased in real time simulation It is an object of the present invention to provide a virtual character adjustment behavior display method and apparatus, and a virtual ecological park visualization system using the same.

1 is a view for explaining a virtual character adjustment behavior display method and apparatus using a 2D texture-based induction field in accordance with the present invention.

Referring to FIG. 1, the method for displaying a virtual character adjustment behavior using a 2D texture-based induction field according to the present invention is an autonomous movement of a virtual character (butterfly, bird, flower) to which a 2D texture-based induction field (誘導 場) is applied. Make this possible. In the preferred embodiment of the present invention, a butterfly ecosystem model using a 2D texture-based induction field is shown. The butterfly ecosystem model is composed of a butterfly agent and a flower agent as a static agent. Each agent has a 2D texture representing the induced field. In addition, the 2D texture induced field calculates the control force of the butterfly, an autonomous agent, through mutual blending in a grid-shaped navigation field constructed in virtual environment space.

The virtual character adjustment behavior display apparatus using the 2D texture-based induction field according to the present invention includes a virtual character database 20, a guidance field database 30, a navigational field generation module 42, and a steering action module 44. Display the movement of the virtual character.

At this time, the virtual character database 20 is composed of the data of the virtual character animated on the screen, such a virtual character database 20 is a dynamic virtual character database 22, such as a butterfly and a static virtual character database, such as flowers It consists of 24. The database 20 of the virtual character has an initial value by input of the database and is updated in the process of performing the method according to the present invention. The induced field database 30 is composed of data obtained by 2D texture imaging of an induced field having a shape, size, and color determined according to characteristics assigned to each virtual character of the virtual character database 20. The voyage generation module 42 maps the guidance field data loaded from the guidance field database 30 and the data of the agent loaded from the virtual character database 20 to form a navigation field. And, the steering action module 44 calculates the steering force for the agent according to the data generated from the airfield generation module 42, the element action from the virtual character database 20 and the internal state of the agent. Here, the agent state converted through the voyage generation module 42 and the steering action module 44 updates the database 20 of the virtual character. The calculated agent state is transmitted to the display device through rendering and displayed on the screen (display). On the other hand, the induced field generating module 40 for forming the induced field by the user's definition may be installed.

Such a method and apparatus for displaying a virtual character adjustment behavior using a 2D texture-based induction field according to the present invention can be processed in real time even with an increase in the range and number of interactions of autonomous agents, and requires NPC control or crowd scene in an online game. In addition to being widely applied to film, it can also be used in the study of human and social behavior in architectural and urban design and in training and emergent evacuation.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, FIGS. 1 to 13, and in each drawing, a technique for realistically expressing the motion of an animal or insect based on a conventional autonomous agent, and expressing a 3D stereoscopic image Detailed description of the technology easily applied by those skilled in the art from the technology for, the technology of capturing the movement of the person and the movement of the virtual character, and the like will be omitted.

FIG. 2 is a diagram for describing induction field generation module in detail in a method and apparatus for displaying a virtual character adjustment behavior using a 2D texture-based induction field according to an exemplary embodiment of the present invention.

Referring to FIG. 2, in the method and apparatus for displaying and adjusting virtual character adjustment behavior using a 2D texture-based induction field according to an exemplary embodiment of the present invention, the induced field may have characteristics (range, strength) of other influences of the agent. It is converted into a field such as a magnetic field or an electric field and imaged as a 2D texture. Agents are virtual characters (butterflies and birds, etc.) that are animated on the computer. They have virtual positional information (coordinates) and motion information (mass, velocity, and acceleration). It is a 2D texture of the effect of the agent, and the type of induced field can be set differently for each agent. In addition, various movements can be expressed according to the shape, size, and color of the induced field. The induced field is set by the user according to the characteristics of the agent. At this time, the induced field is based on the 2D texture image. This is more intuitive and effective in reducing the computational cost than using an equation in using an induction field. The user-defined induction field can be stored in the induction field DB and used whenever necessary.

Referring back to FIG. 2, in order to generate an induction field, a 2D texture may be created using a function or an equation. When creating a 2D texture, a picture is created using a frame buffer memory space. The advantage of using the frame buffer is that it has depth information, so it can be useful for blending, and the navigation path to be created also has the advantage of using data because the frame buffer is drawn. In addition, when generating the induced field using a picture file in which the induced field is pre-drawn, data is obtained using an image loader. The advantage of the picture file is that you can see the movement of the chapter intuitively because you can see it as visual information without the need for complicated formulas such as formula creation. The place where the data is temporarily stored by loading the picture file is also stored in the frame buffer and used to create the navigation field.

3 is a view illustrating in detail a navigational field generating module in the virtual character adjustment behavior display method and apparatus using a 2D texture-based induction field in accordance with a preferred embodiment of the present invention, Figure 4 is a 2D in accordance with a preferred embodiment of the present invention A virtual character adjustment behavior display method and apparatus for displaying a virtual character adjustment behavior using a texture-based induction field, and FIG. 5 illustrates a virtual character adjustment behavior display method using a 2D texture-based induction field according to an exemplary embodiment of the present invention. And a diagram for explaining blending of a color-based induced field in an apparatus.

Referring to FIG. 3, in the method and apparatus for displaying and adjusting a virtual character adjustment behavior using a 2D texture-based induction field according to an exemplary embodiment of the present invention, a navigation field means that a plurality of induction fields are generated to generate one field. Navigation field generation retrieves the shape of the induction field from the induction field DB and the position and state of the agent in the butterfly and flower DB. The imported information is mapped to the voyage according to each information. The voyage is classified and managed by the characteristics of the high field. The reason for managing separately by characteristics is that the voyage required by the agent may be different for each agent. The navigator can express unique movements through the combination of navigator interactions between agents.

At this time, based on the information obtained from the virtual character (butterfly, flower, etc.) DB, the induced field is selected from the induced field DB to freely transform the size of the induced field image according to the range of influence. The selective induction field converts the color and size of the induction field image to express the magnitude, intensity, and position of the influence according to the agent state. In addition, it maps to the position of the corresponding voyage among several voyages to be drawn according to the kind of guidance field. Once the shape of the induced field is determined, as shown in FIG. 4, the induced field is mapped to the position of the agent. The guidance field mapped to the voyage is used to calculate the steering force for the agents. When two or more multi-blends are required in the future, the color information is blended, and thus, blending processing is performed as shown in b) of FIG. 5 so that the original color information is not damaged as shown in FIG. Once the mapping of the taxiway to the location of the agent is completed, a navigator is completed.

On the other hand, when several guidance fields are combined in one voyage, errors may occur in the information and there is a limit in the expression of the movement. In the present invention, it is possible to process by generating and managing several voyages. By hierarchizing a plurality of voyages, the agent can select the voyages needed by the agent and read the data. In addition to reading data from only one landing, you can select several landings to read the data.

FIG. 6 is a diagram for describing in detail a voyage generation module in a virtual character adjustment behavior display method and apparatus using a 2D texture-based induction field according to an exemplary embodiment of the present invention.

Referring to FIG. 6, the virtual character (butterfly, bird) control action animation generation is determined according to the data from the voyage and the element action taken from the butterfly DB and the internal state of the agent. Factor behavioral forces also provide the forces (data values) that combine the forces determined by the state of the agent and the calculated forces at the yard with the forces of factor behavior to enable the agent to act. At this time, the ratio of the forces to be combined can be adjusted according to the agent state. The calculated steering force of the agent updates the agent's position to generate an animation of the movement.

First, the basic behavior of the butterfly agent was applied to eight kinds of behaviors (Wander, Seek, Flee, Arrive, Pursue, Evade, Offset, Pursuit). And while there are more maneuvers, other maneuvers have interactions between agents. Since the interaction between agents is represented by the voyage, the control action with the interaction is excluded from the basic control action. The basic maneuvering behavior controls the agent's movement when no information can be obtained from the airfield or when the agent's status does not read the airfield information. And even when receiving information from the yard, the force of the basic maneuvering behavior is calculated according to the agent's status.

FIG. 7 is a diagram illustrating a grid arrangement around an agent when processing data of a voyage field in a method and apparatus for displaying a virtual character adjustment behavior using a 2D texture-based induction field according to an exemplary embodiment of the present invention, and FIG. In the method and apparatus for displaying a virtual character adjustment behavior using a 2D texture-based induction field according to a preferred embodiment, it is a view for explaining the calculation of a steering force according to an agent's state in processing data of a navigational field.

In a preferred embodiment of the present invention, the virtual character (e.g., butterfly) agent is a scalar value (red: 1 to 255, green: Read from 1 to 255, blue: 1 to 255, that is, an 8-bit integer value for each of RGB). Using the read scalar value, the vector value in 8 directions is obtained by subtracting the grid in 8 directions from the center of each agent. The largest vector among these vector values is used as the force acting on the agent and becomes the direction of the steering force. As shown in FIG. 7, the steering force vector V for generating a motion reads a scalar value of a navigation field from A1 to A9, which is a grid around an agent, and obtains a vector V through an operation as shown in Equation (1).

The value obtained here is the movement control to the virtual character agent calculated at the voyage. This control is equal to the number of airfields and is applied to the agent depending on the state. In addition, when applying the obtained control force to the virtual character, the forces of all the aerodromes and the forces of the element behavior are not applied in combination, as shown in FIG. 8, the combination of the forces is applied according to the state of the agent. The virtual character agent, such as a butterfly, updates its position and updates its internal state based on the force determined in the control action module. All agents have different influences and strengths at the voyage depending on their internal condition.

9 is a view for explaining a virtual butterfly agent state machine in a method and apparatus for displaying a virtual character adjustment behavior using a 2D texture-based induction field according to an exemplary embodiment of the present invention.

Referring to FIG. 9, in the preferred embodiment of the present invention, the virtual butterfly character agent model is represented by three internal states. Each state has a state of hunger, tiredness, and reproduction. The basic condition of a butterfly is to roam. The wandering state is a state in which movement is determined by the action of one's own elements without being influenced by the environment (flower). Roaming is prioritized in order of updating its internal status: Hunger>Tired> Breeding. When Hunger is checked, the agent's status switches to Roaming-> Flower Finding. Accordingly, the combination ratio of the forces is changed. Among the voyages accepted, the voyages have a greater influence on the strength of the field with respect to flowers. When wandering under the influence of a flower's bowel, other types of agents will be asked for the type of status agent. If the other agent is not a flower, it roams in the flower search state again. If the other agent is a flower, it will switch to the flower search state-> eat honey. When you eat honey, you will fill your hunger and relieve some fatigue. When hunger disappears, one's state is switched to roaming again, changing the combination of powers. If you feel tired while roaming, you will switch to Roaming-> Resting. The combined rate of force in a tired state does not accept element maneuvering behavior and the voyage reads only the chapters of the hazard. When the butterfly stops moving, the tiredness is released. If a danger is detected during the rest period, the butterfly moves to a space without the risk and rests. As with hunger, when the tiredness is released, it goes back to roaming; the last state of breeding is the same as the above 2 states. When the state changes, the combination ratio of the force changes, which leads to a control action, and when the state of reproduction is eliminated, it goes back to roaming and roams until it becomes another state.

FIG. 10 is a diagram illustrating a virtual flower agent state machine in a method and apparatus for displaying a virtual character adjustment behavior using a 2D texture-based induction field according to an exemplary embodiment of the present invention.

Referring to FIG. 10, in a preferred embodiment of the present invention, the flower agent is a stationary agent. Therefore, the control behavior is not calculated, only its internal state is updated. The inner state of the flower is changed whether or not there is a butterfly on its peak. Resting in the absence of a butterfly has only a role in spraying its judo ground on the voyage. When the butterfly sits on the peak, the butterfly transitions to a state of eating honey. The butterfly is eating honey, rejecting the message from sitting on other butterfly peaks and subtracting its honey from the amount of honey the butterfly has eaten. When the butterfly eats honey and leaves, it returns to rest. But if the butterfly runs out of nectar and the honey falls, the message to the butterfly to leave and the butterfly goes to the state of eating honey-> making honey. The honey making state rejects the butterfly until the honey fills up without spraying its judo ground on the voyage. When the honey is full, it will switch to the honey making state-> rest state and wait for the butterfly to come.

In addition, referring to FIG. 12, it can be seen that the butterfly agent is attracted to the induction field of flowers or avoids from the new agent.
