Various virtual reality methods are examined on the internet. In this paper, 3D implementations on the internet are discussed using Java3D and GL4Java which are based on the Java. 3D shoppingmall, real time 3D renderings, and various objects are implemented using Java3D and GL4Java, respectively. Especially with Java3D, the file formats of VRML97, OBJ, and 3DS are implemented using Java3D loader, which shows that object implementation in Java3D is better than other methods. Also, the comparisons between Java3D and GL4Java are discussed.

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.
