Abstract:High resolution texture is the most commonly used method to strengthen terrain authenticity. The huge higher data of solution texture have surpassed the limits of the computer graph render equipment. Therefore, it needs the piecemeal texture. In order to address the insufficiency of the conventional manual texture piecemeal, this paper has produced the image texture automatic piecemeal principle and method, and proposed a dynamic multi-resolutions texture model. It gets texture resolution method based on the viewpoint, and designs the data construction to management texture and the database memory program. The experiment proves that this method does not only reduce the demonstration quality, but is also able to effectively reduce the texture quantity and obtain a better visible effect.
