Projected Displaced-Mesh: A Fast Terrain Visualization Algorithm

摘要：

We present an algorithm called Projected Displaced-Mesh (PDM) based on projected-grid for terrains. This algorithm is different from the previous algorithms. Our algorithm uses Displaced-Mesh. It creates terrain mesh by projecting, and then displaces the vertices from height field. Because of the use of projection, the algorithm has automatic view dependent Continuous Level of Detail (CLOD), automatic view frustum culled characteristic, and there is no limitation on view position. The experiment shows that our algorithm generated a high quality image and has a very fast rendering-rate.
