| Hgh-order polynomial curve and surface become more and more popular in fieldsrelated to computer graphics, and deserves applying in3D modeling. To make thegraphics a illusion with required precision, yet survive without display delays is ahighlighted point in recent research, this paper devotes to present a method with thesecharacters in height fields application.A new method is brought forth to calculate view-dependent multi-resolutiongraphics. Other problems such as quad-tree storage problem, interval revise andtechniques for enhancing efficiency and visual experience are also included in the set ofproblems being discussed. In addition to it, here a pre-calculation idea is brought intoreality, which also applied to data acquired in remote sensing.The contents here contains methods to achieve good flexibility in differentconditions，which is an obvious advantage compared with known methods. It runsexcellently in real-time condition and in the same time provides great visual experience. |
