摘要: We describe a terrain rendering algorithm for spherical terrains based on clipmaps. It leverages the high geometry throughput of current GPU to render large static triangle sets. The vertices are displaced by height map texture. Our main contribution is mapping texture coordinates calculate sample position vertex offset and variable view position.
