A technique of massive scale data management and attemperation based on viewpoint. This algorithm effectively changes massive scale terrain into large scale ones to handle. Utilising the continuity of the viewpoint movement and the relativity of fore-and-aft frames, it manages and attempers the terrain data leading to data decrease in a large range. This algorithm solves the problem of the rendering rate, and realizes a rapid real-time ramble in massive scale terrain scenes.
