Error metric is the key problem for generating level of detail of terrain surface, which affects the deviation between the number of triangles and triangular mesh. After analyzing various present methods of calculating error metric, we present an improved algorithm based on roughness. This paper takes the roughness which expresses relief amplitude to be an factor, by which we calculate the error metric,...
