In this paper, we propose a system and an intuitive interface that can create an athletic scene among athletes. We allow you to enter motion as if you were playing a game, so that the user's action becomes the player's action. The user can take various actions in front of the motion sensor and control the object flying to him. When a user specifies an opponent to pass or attack, and takes appropriate action in front of the motion sensor, the movement trajectory of the object is automatically generated by the physical optimization technique in accordance with the motion. In this way, you can create scenes where multiple players play together in a virtual environment. The method of this paper will be very useful for rapid prototyping for cinematic trailers of based on athletics games or animations.

AI blockchain technology, which is attracting attention as a core technology of the 4th Industrial Revolution, is a technology that can be used as an important means of innovation not only in the current gaming industry but also in various industrial fields. This paper extracts the platforms and types of blockchain games currently ranked within the top 100 on the blockchain app (DApp) sites State Of The DApps, DApp.com, and Dapp Rader and introduces the top games on major platforms. As a result of extracting platforms and types, the top games were mainly based on Ethereum, EOS, and Steam. However, the results showed that there are significantly more games based on the Ethereum platform, which are stable, easy to apply, and have a low barrier to entry due to the large number of users and DApps. We plan to improve awareness of blockchain games by studying the characteristics that only blockchain games have.

First of all, What was the modeling technique used to model 3D-Game character? It's a technique developed along several years, by experience... here is the bases Low polygons characters I always work in low polygon for two reasons -You can easily modify a low-poly character, change shapes, make morph for facial expressions etc -You can easily animate a low-poly character When the modeling is finished, Second, In these days, Computer hardware technologies have been bring about that expansion of various 3D digital motion pictured information and development. 3D digital techniques can be used to be diversity in Animation, Virtual-Reality, Movie, Advertisement, Game and so on. Besides, as computing power has been better and higher, the development of 3D Animations and Character are required gradually. In order to satisfy the requirement, Research about how to make 3D Game modeling that represents Character's emotions, sensibilities, is beginning to set its appearance. 3D characters in 3D Games are the core for the communications of emotion and the informations through their facial expression and characteristic motions, Sounds to Users. All concerning about 3D motion and facial expression are getting higher with extension of frequency in use. Therefore, in this study we suggest the effective method of modeling for 3D character and which are based on 2D Graphics.

This study examines the legend of 'Grandmother Seolmundae and Five Hundred Generals', the cultural archetypes of Jeju, and analyzes the characteristics of its contents. After analyzing the feasibility of using the analyzed cultural prototype as cultural contents such as games and animations, based on this analysis, we tried to suggest a cultural planning approach based on the cultural prototype to the cultural agency. Therefore, the implications of this study are as follows. First, among the cultural prototypes in Korea, 'Grandmother Seolmundae and Five Hundred Generals', which represent the legends of Jeju Island, are being organized centered on many historical researchers and Chaerokga, but there is no precise establishment of the exact timing of the legend and how it arose. Therefore, when planning and developing content based on the cultural prototype, it is most important for cultural agencies to develop a story after researching historical evidence and opinions of local residents to identify a consistent point of view. Second, although the contents of the cultural archetype are arranged slightly differently by historians and recorders, the main contents and characteristics of the story are found to have a similar form. Therefore, cultural agencies should focus on finding the point of view and characteristics of a story, even if a story is written differently by different people when doing a cultural prototype. Third, when planning a game based on the cultural prototype, the main elements such as the elements to be expressed in the game and the fun elements should be found and presented. In particular, because fun and rules are the most important parts of games, if this part cannot be derived from the story of the cultural archetype or cannot be made, it is difficult to transform the cultural archetype into a game. Therefore, it can be seen that it is important for cultural agencies to set their game plan intentions in consideration of story expression and fun, even if it is the core or non-core of the entire story of the cultural archetype. Lastly, although the cultural prototype 'Grandmother Seolmundae and Five Hundred Generals' was presented as animation content, it is important to develop it considering the story, characters, media, and audience. Therefore, cultural agencies should be able to derive the elements such as stories, representative and auxiliary characters, and viewers that can be adapted from the cultural prototype as much as possible. It will be an important part of raising.

Body motions are commonly used to express emotions in virtual characters based on body parts, which are frequently employed in games. For this purpose, it is necessary to create different types of animations corresponding to the emotions shown by virtual characters. Therefore, a large of number of animations should be created for different gestures depending on the level of human emotion. In this paper, we propose a method for displaying gestures with various degrees of complexity on the basis of the level of emotion in virtual characters. In particular, this method can be used to display passive and exaggerated expressions by adding weighted values to the frames that rotate the characters to make them show different gestures depending on the level of emotion. To verify the effectiveness of the proposed method, we use the Emotional Animation Tool (EATool), with which body-weighted values can be applied to the actual or virtual characters. After assigning different emotions to walking motions in the newly developed environment, we apply different body-weighted values depending on the level of each emotion. The results of a comparative test reveal that a given type of walking motion differs with the level of emotion.

A motion capture system is widely used in movies, computer game, and computer animation industries because it allows for creating realistic human motions efficiently. The inertial motion capture system has several advantages over more popular vision-based systems in terms of the required space and cost. However, it suffers from low accuracy due to the relatively high noise levels of the inertial sensors. In particular, the accelerometer used for measuring gravity direction loses the accuracy when the sensor is moving with non-zero linear acceleration. In this paper, we propose a method to remove the linear acceleration component from the accelerometer data in order to improve the accuracy of measuring gravity direction. In addition, we develop a simple method to calibrate the joint axis of a link to which an inertial sensor belongs as well as the position of a sensor with respect to the link. The calibration enables attaching inertial sensors in an arbitrary position and orientation with respect to a link.

These days, mobile technology is developing very fast. It has increased the usage of the Internet by mobile phones. Nowadays the avatar and game contents services are most popular in mobile phones using the Internet. In this paper, we propose a Client/Server system to combine the animation avatar and e-mail services on SK-VM which are different from simple avatar services. The server which consists of DB (database) module and mail management module is designed in order to manage the information about avatar and the user. The client is designed so as to show the email contents and avatar animation on the mobile phone. This model is intended to reduce the performance overhead on the client as much as possible. We expect that this module would be useful in the mobile phones with limited resources, although the technology is being developed very rapidly.

In computer graphics, fluid dynamics are used for animating and expressing the various special effects of water. Although the algorithms that were impossible through the hardware at that time become to be possible in real time, it still requires a lot of time to achieve the realistic and detailed expressions. Therefore, there are many researches on the techniques of balancing between performance and quality. Specially in environments with the game context which express the interaction between water surface and 3D objects in the wide area such as sea or lake according to user's request, it must give priority to the executive performance preserving the visual reality even though physical reality is sacrificed. In this paper, we propose a method for the realtime animation of interaction between water surface and 3D objects using the linear convolution of height fields and the bounding spheres of objects.

In virtual environments, such as computer game and animation, we need to enhance naturalness of crowd simulation. So, we propose a method to generate dynamically moving crowd patterns by applying emotional factors to the individual characters of a crowd in the determination of their behavior. The proposed method mimics human behavior and controls each character in a group to decide its own path according to its individual status. And it is able to generate various moving patterns as a result of letting the individuals go to another group depending upon their conditions. In this paper, some temperament and feeling factors are defined and determination rules for calculating the emotional status are also proposed. Moreover we use a fuzzy theory for accurate representation of the ambiguous expressions such as feeling bad, feeling good and so on. Our experiments show that the suggested method can simulate virtual crowd in more natural and diverse ways.

In this paper, I study the development of character in the fantasy genre of trans-media contents. In this study, I studied the novel " Songs of Fire and Ice " from the existing fantasy genre, and found that the content was expanded to include characters and features that were important to compared with the other fantasy genre content. Late fantasy genre writers since The Lord of the Rings have inherited a sort of genre of standards, and have established the genre of high fantasy. The genre has a typical characteristic of heroic characters or group adventures, based on the stage 12 heroic epic by mythologist Joseph Campbell. So the body of this paper will explore the journey of the heroic character in " Songs of Fire and Ice" and will be compared to the mythic motif and to the heroic epic narrative, and then find out the exceptional features of " Songs of Fire and Ice " as a fantasy genre.
