Correct flow of various game manufacture among the justice which is used at the game development. and The understanding about the manufacture regards we making rather correct game. We justice understanding which we are correct in the image manufacture to become the reason air control of the game and We put the center in a 3B game image manufacture understanding. we are marked in maneuvered the game in actual game good. The image of the back of Cut Scene which is inserted at an opeuning incomparableness event time, we have been produced in this method. The thing which a 3D game image is utilized in a special effectiveness image though it is different from the game in the theater movie, we are the graphic which a game manufacture o'clock must be considered. The reason air control which the game player Is rather correct, we are regarded we offer the reason to immerse with his game.

In the Contents industry, especially in the field of game contents the area receiving the most spotlight is 3D. With qualitative and quantitative developments in games continue, interest in 3D is becoming more significant. As a result studies and actual application in the area of 3D in the game industry are being most actively conducted. It is true that 3D game characters do not have the same level of natural movement compared to the previous 2D characters. In order to overcome the limitations of movement control of the Key frame method, the method that is currently being rapidly developed is a movement control method using motion capture system. In this study, the focus is placed in production of natural character animation through movement control through linkage of 3D game characters and motion capture system. Hence, production of natural 3D game character animation through a single central action was established as the purpose of this study.

In this paper, we consider the game theoretic approach to investigate the transmit power optimization problem where D2D users share the uplink of the cellular system. Especially, we formulate the transmit power optimization problem as a non cooperative power control game. In the user wide sense, each user may try to select its transmit power level so as to maximize its utility in a selfish way. In the system wide, the transmit power levels of all users eventually converge to the unique point, called Nash Equilibrium. We first formulate the transmit power optimization problem as a non cooperative power control game. Next, we examine the existence of Nash Equilibrium. Finally, we present the numerical example that shows the convergence to the unique transmit power level.

In this paper, we propose a new method of generating 3D face by using single frontal face image and 3D generic face model. By using active appearance model (AAM), the control points among facial feature points were localized in the 2D input face image. Then, the transform parameters of 3D generic face model were found to minimize the error between the 2D control points and the corresponding 2D points projected from 3D facial model. Finally, by using the obtained model parameters, 3D face was generated. We applied this 3D face to 3D game framework and found that the proposed method could make a realistic 3D face of game user.

The market of digital avatar with internet and digital technology is increasing rapidly. The users want to express any free-formed motion of their avatars in the cyber space. The user s motion capturing method as the avatar's motion can express any free-formed motion of the avatar in real-time but the methods are expensive and inconvenient. In this paper, we proposed a new method of expressing any free-formed motion of the avatar in real-time. The proposed method is an algorithm for real-time control of a 3D avatar in symmetry-formed free motion. Specially, the algorithm aims at the motion control of a 3D avatar for online dancing games. The proposed algorithm uses the skeleton character model and controls any one of two hands of the character model by a joystick with two sticks. In the symmetry-formed motion, the position and orientation of one hand can determine the position and orientation of the other hand. And the position and orientation of a hand as an end-effector can determine the pose of the arm by Inverse Kinematics. So the algorithm can control the symmetry-formed free motions of two arms by one joystick with two sticks. In the dance game, the algorithm controls the arm motion by the joystick and the other motion by the motion captured DB.

Recently the unprecedented progress of Android platform and Google Play has brought more opportunities for individual mobile game developers. When playing an Android 3D game, users can accidentally hit HOME Key or BACK Key or receive an incoming message. Subsequently, another screen will appear on top and make the game application lose focus, or the operating system pause that game. These interruption events may also lead to the loss of game information or the game runs out of user control if that game cannot catch interruption events itself and resume at the exact time. As same as other mobile platforms, Android platform also provides Activity Lifecycle methods to help the game application control interruption problems. However, these methods are not adequate to solve all the interruption events. By implementing ANDCube game, we examine most of the possible interruption cases and propose some solutions to help Android game developers avoid some common interruption cases. Concurrently, we show the ways how a game application can catch all unavoidable interruption events and effectively resume from interruption to obtain a high quality game.
