In this study, we concentrate our attention on the real-time
visualuation of multi-resolution terrain models and analysis
of scene complexity management on a general PC platform. We
implement an algorithm for real-time level-of-detail generation
of terrain models using symmetric triangulation networks which
was proposed by Lindstrom et al. [30]. In this study, we propose
a quadtree data structure to satisfy the execution of the algorithm
and the usage of used toolkit. We also modify the algorithm
such that the algorithm is more suitable for a low-end personal
computers. Based on the algorithm, we evaluate several different
performance PCs, and find a proper criterion to match the finest
performance and display quality for every computers.
