Adding Advanced Debug Output Features to an Existing OpenGL ES 1.1 Implementation

With modern integrated development environment, support for error reporting and debugging features becomes more important. In the case of 3D graphics libraries, the OpenGL (Open Graphics Library) has introduced the KHR_debug extension, and it becomes the core feature of OpenGL version 4.3 and later. In contrast, existing OpenGL family implementations are lack of these features and hard to update the existing device drivers. In this paper, we represent a dynamically-linked library (DLL) wrapping approach to support the KHR_debug extension even on the old OpenGL ES 1.1 versions. Our prototype implementation shows full features of the KHR_debug extension and works well with existing OpenGL ES 1.1 application programs. This enhancement to the OpenGL ES 1.1 enables the application programmers to use more up-to-date debugging features with traditional graphics drivers.
