Recently real-time overhead processing technology has received great attention from many researchers since it is expected to play a great role in improving frame per second. Also, this technology is suitable for flight simulator where large number of vertices as well as high resolution image is demanded. Even though typical culling or level of detail can be applied to flight simulator, more deep consideration is required because flight simulator operates in three dimensional space in the air. Among the possible technologies, view-frustum culling is one of key research area by improving rendering speed. But, despite of importance, since unnecessary data processing remains, it is reasonable to execute culling technology by adding the several elements such as aircraft altitude information, pitch angle dynamically. To develop a new dynamic culling, in this paper, we propose hybrid dynamic culling scheme by combining the view-frustum and the back-face culling together. The proposed culling scheme uses the fuzzy logic to determine culling ratio based on aircraft state information for visibility test. Finally, we demonstrate that the proposed scheme shows faster rendering speed than current culling scheme through experimental scenarios which are implemented by open source Open Scene Graph graphic library.
