碩士 === 國立交通大學 === 多媒體工程研究所 === 95 === The libraries such as Abstract Window Toolkit (AWT) and Swing used to develop Graphical User Interface (GUI) are the key parts of rendering performance for applications designed in Java. However, the rendering performance in Java is not very efficient. While new Java versions are released to improve rendering performance, some users still keep using the old ones. They cannot have the benefits from the new Java releases. In addition, the applications, which were developed in the old Java releases, cannot get the benefits of improving rendering performance from the new ones unless modifying the source codes for new APIs. Moreover, the performance of Java on different operating systems is inconsistent. It is hard to estimate the performance of Java applications for developers. To improve rendering performance in Java and let the existed Java applications benefit from this, this thesis implements the OpenGL part based on CYC Window Toolkit (CWT)[32]. We do all rendering operations with OpenGL and optimize the rendering performance to achieve: performance improvement and portable performance on different operating systems.
