Abstract

With recent advent of hardware accelerators for three dimension graphics in appear, the question of how to support them has become a hot topic. OpenGL, designed as a streamlined, hardware-independent interface is the right choice for most graphics programmer who could enjoy real interactive 3D images. In this major report, the author applies the principles of software re-engineering to the. System Visualizer and successfully replaces the display module implemented by PEX with OpenGL. The new System Visualizer still retains the original algorithm, data structures and the parser, but incorporates the lighting, texture mapping, alpha blending, antialiasing, animation and hidden surface removal into the display module which the original system missing. OpenGL enables the System Visualizer run on both NT and X platform and removes the limitation of platform dependence.
