An improving algorithm for generating real sense terrain and parameter analysis based on fractal

摘要

Real sense image generation algorithm is an important part of computer graphics, in which realistic terrain generation has become a difficulty and hot spot in recent years. Virtual three-dimensional terrain modeling uses computer graphics technology to implement. In this paper, based on fractal Brownian motion theory, the classical Diamond-Square algorithm was advanced to form virtual three-dimensional terrain modeling. Terrain Splicing and Stitch Border techniques and terrain texture mapping, light mapping technique were used to deal with the terrain light and texture and stitch the border. The algorithm parameters were also analyzed in this paper and the influence effects of the various parameters on the virtual terrain features was got. With the combining use of Visual C++ 2005 and OpenGL, terrain generation and rendering are achieved. This approach has reached the expected results and a realistic three-dimensional graphics effect was obtained.
