In this paper, we present a new terrain rendering approach, with adaptive triangulation performed entirely on the GPU via tessellation unit available on the DX11-class graphics hardware. The proposed approach avoids encoding of the triangulation topology thus reducing the CPU burden significantly. It also minimizes the data transfer overhead between host and GPU memory, which also improves rendering performance. During the preprocessing, we construct a multiresolution terrain height map… CONTINUE READING
