The game engine has executed an application after making a mobile 3D game engine which is based on mobile 3D standard graphic API using openGL-ES so far. But, We could not do it satisfactorily that contents compatibility of various types as a various low-level's function is supported. At this point, This study introduce a mobile 3D game engine which is based on mobile 3D standard graphic API using JSR-184 that supporting a high-level's API more than openGL-ES and optimizing to Java environment on J2ME in the center of GSM phone. Also, We shows that the proposed skinned-mesh scheme for enhancing the process speed of a 3D object on JSR-184 engine. The experimental results are shown.

This study focuses on modeling mobile 3D game engine and suggesting modified skinned-mesh schema based on JSR-184 in order to improve the performance in terms of memory consumption and time complexity. Most of the 3D games have used OpenGL-ES low-level APls, which may limit portability and fast developing time. Hence, the 3D mobile game engine providing high-level APls which works on GSM (Global System for Mobile Communication) phones on J2ME, is proposed here in order to optimize the performance for Java environment abiding JSR-184 standard. To prove performance enhancement, skinned-mesh schema on JSR-184 engine is modified and tested. The experimental results are shown.

This study focused on design and implementation of Mobile 3D Bluetooth Engine based on OpenGL-ES. In Mobile 3D network game so far, there is a form the mainstream of wireless internet game using WAP and VM. But, VM game are popular because of an excessive communication expense problem for this mobile network game that occur when connect to wireless internet as point out to problem by it, that is, stand-alone game are very popular. This study introduce a mobile 3D Bluetooth Engine which is based on mobile 3D standard using OpenGL-ES to solve a mobile network game generally that occurs when connect to take pleasure a wireless internet from some people into a short distance.

This study focused on design and implementation of Mobile 3D Bluetooth Game Engine based on OpenGL-ES. In Mobile 3D network game so far, there is a form the mainstream of wireless inter-net game using WAP and VM. But, VM game we popular because of an excessive communication expense problem for this mobile network game that occur when connect to wireless internet as point out to problem by it, that is, stand-alone game are very popular. This study introduce a mobile 3D Bluetooth Game Engine which is based on mobile 3D standard using OpenGL-ES to solve a problem like mobile network game generally that occur when connect to take pleasure a wireless internet from some people into a short distance. When the number of concurrent packet datum by Bluetooth terminal transfers to each other, we shows that the proposed scheduling scheme for enhancing the process speed up on Bluetooth.

PDA와 같은 이동단말에서 화려한 3D 그래픽을 보여주는 것은 그래픽 시스템 리소스의 제약이 있다. Mobile 3D 엔진은 모델의 움직임을 계산하여 동적으로 3D 그래픽을 만들어 내기 때문에 그래픽 시스템 뿐만 아니라, 충분한 성능의 프로세서와 여유의 메모리까지 지원되어야 한다. 본 논문에서는 Mobile 3D 엔진의 제약 사항과 그 해결 방법을 제시하였다. ARM9 Core를 기반으로 3D 가속 기능을 가진 VRender3D에 실제로 OpenGL/ES를 기반으로 하는 Mobile 3D 엔진을 포팅 (porting) 하고, 그 성능을 동적인 3D 영상으로 평가하였다.

As digital contents based on 3D graphics are increased, the requirement for low power 3D graphic hardware for mobile devices is increased. We design a transformation engine for mobile 3D graphic processor. We propose a simplified transformation engine for mobile 3D graphic processor. The area of the transformation engine is reduced by merging a mapping transformation unit into a projective transformation unit and by replacing a clipping unit with a selection unit. It consists of a viewing transformation unit a projective transformation unit a divide by w nit, and a selection unit. It can process 32 bit floating point format of the IEEE-754 standard or a reduced 24 bit floating point format. It has a pipelined architecture so that a vertex is processed every 4 cycles except for the initial latency. The RTL code is verified using an FPGA.
