Self-Adjust Terrain LOD Rendering Based on GPU

Abstract:

This paper presents a kind of adaptive rendering algorithm based on the data structure of patch block. It adopts the Tessellation technology and index template technology .The terrain is rendered through the index template technology when it does not need high precision geometric characteristic. The paper presents the calculation model of subdivision coefficient based on the patch boundary and deals with the result of the calculation when the terrain needs high precision geometric characteristic. The result of the experiment indicates the algorithm can improve the rate of frame and the effect is more reality. The terrain of higher detail will be rendered when we input more rough grids.
