Clipmap based Loading and Rendering of Large Terrain Texture

摘要：

In order to meet the needs of rendering of large terrain, the loading and rendering methods of largescale terrain texture are studied. A framework of terrain texture real-time loading and rendering is presented based on clipmap and texture blocks. Texture update and texture sampling are researched and the situations of viewer quickly moving and viewer in high are considered. A method of texture garbage collection based on viewer shift is presented to avoid the failure of fetching texture and to release the unused texture quickly. The results show that the method is simple, efficient and can be used in large terrain texture rendering.
