The large-scale terrain generation based on GPU texture synthesis
Ying Tang, Xiaoying Shi, Jing Fan · 2011
The real-time rendering of large-scale terrain has been widely used in driving simulation, virtual battlefields and 3D games. Large-scale terrain holds huge geometric and textural data. How to generate and render large-scale terrain in real time with limited computing resources is a big challenge. Different from the previous out-of-core terrain roaming methods which are based on complex scheduling algorithm, in this paper the terrain data is synthesized on GPU on the fly. Our method generates large-scale complicated geometric and textural data for large-scale terrain in real-time without the need to exchange the data between the internal and external storage frequently. This paper also proposes user friendly interactive texture synthesis, which generates the terrain within a window specified by the user in real time. Our method is simple and easy to be implemented. The experimental results show the effectiveness of our method.
