Research on large-scale terrain landscape generation technology based on bitmap

terrain models;  DEM;  Gaussian filtering

The convenient and effective establishment of terrain model and its texture is the focus of terrain landscape research. By using the method of establishing terrain landscape based on bitmap, the mapping relationship between the gray value in the bitmap and the terrain elevation is established, and the smooth terrain model is automatically created by combining image processing technology, and the texture that can express a variety of surface features can be automatically generated, and finally the terrain landscape with realistic effect is generated. This method is simple and convenient, and can be built and modified as you like, and is suitable for game production, virtual scene construction, and other fields.
