Using the multiresolution technique is one way to archive the real-time rendering for the large-scale environment visualization; however, most multiresolution techniques did not consider the appearance of the environment, then the shapes of the models and environment are degraded during lower-resolution rendering. We here presented a multiresolution modeling algorithm using quadric error metrics and provide the error metrics with the appearance attributes of a model such as color, normal and texture coordinates to rapidly obtain multiresolution models with high qualities. The view-dependent technique is one way to further improve the rendering performance of multiresolution models. We here also provide the view-dependent technique for automatically deciding the proper resolution and model structure based on the view parameters to archive a real-time visualization.
