The next generation of 3D mobile games market is becoming increasingly active, more as a result of improvement in the CPU speed of hardware phone, embarkation of 3D engines and high memory capacity, In response to this trend, popular 3D games of PS2 (PlayStation2) and popular online games are being launched as mobile games. However, mobile units have different hardware characteristics compared to those of other platforms such as the PC or the game console. Therefore, mobile game versions of the popular PC games face many limitations in many aspects such as in battery capacity, size of display, capacity of the game, and other user interface issues. Among these many limitations, study for allowing low capacity storage of the game is becoming important. In addition, realistic animation of the 3D character on the small screen of the mobile unit is more important than any other matter. The purpose of this study is to find a solution to providing realistic 3D character animation, and for decreasing the storage capacity of character animation for application in 3D mobile games.

This paper presents a real-time fire simulation on the mobile phone using stable fluid animation techniques. Stable and fast fluid simulation methods are developed in PC and console games, but fluid simulation and interactive fluid models require too much system resources for applying on mobile environment. We studied and implemented physics-based models for fluids like fire and smoke effects using billboard and stable fluids simulation method on mobile 3D system. The mobile platform of our system is WIPI, which is the standard mobile platform in Korea, also we adopted NF3D API for our 3D programming API. We implemented real-time fire simulation and added it in mobile 3D game, "Rupee Story".

In the rapidly changing mobile app market, it is crucial to develop a good idea quickly and receive its market evaluation. For a small-sized company, however, it is very challenging to rapidly develop and deploy their products in response to highly fragmented mobile environments. This article demonstrates that our integrated development environment using both React Native and Unity3D when developing a mobile app achieves a high level of functionality and performance requirements successfully. Moreover, this integrated environment helps reduce development costs and shorten development time.

Due to smart phones introduced since 2007, mobile contents production become activated and with this trend, attention among different age groups to production of mobile games has been growing. Whereas in the past, development of games was the domain of developers equipped with technical knowledge, provision of editor-type engines in recent times is lowering the high barrier of entry to game production. This paper proposes an event-based module design method from the perspective of general users, aimed at producing games by oneself with a Unity 3D, one of editor-type game engines. This is to plan behaviors and roles in the unit of modules in the whole process of a game to be in line with the perspective of game production by one person. Each module includes diverse events that express game characteristics. In addition, the script function provided by the Unity 3D is appropriate to embody the proposed module structure and utilizes the Unity 3D. Lastly, this study produce a simple 3D mobile casual game in order to verify whether effective game production from the planning to the development is possible through the proposed method.

Mobile devices is getting to include more functions according to the demand of digital convergence. Applications based on 3D graphic calculation such as 3D games and navigation are one of the functions. 3D graphic calculation requires heavy calculation. Therefore, we need dedicated 3D graphic hardware unit with high performance. 3D graphic calculation needs a lot of complicated floating-point arithmetic operation. However, most of current mobile 3D graphics processors do not have efficient architecture for mobile devices because they are based on those for conventional computer systems. In this paper, we propose arithmetic units for special functions of lighting operation of 3D graphics. Transcendental arithmetic units are designed using approximation of logarithm function. Special function units for lighting operation such as reciprocal, square root, reciprocal of square root, and power can be obtained. The proposed arithmetic unit has lower error rate and smaller silicon area than conventional arithmetic architecture.
