Textures are an important element to simulate real scenes. When textures are applied to each scene, the most important step to more realistic simulation of the real world is to solve the sense of repetition caused by texture tiling. Therefore, in order to simplify the process of texture image production and deal with the seams when texture tiling, this paper improves the traditional procedural texture generation algorithm based on the traditional one. First, this paper proposes an imagebased method to deal with the seam problem caused by structured texture tiling, and also proposes a new algorithm to solve the texture repetition problem caused by large-scale tiling. The algorithm synthesizes infinite outputs with the same appearance using random texture blocks as inputs, with random textures, such as overlapping rocks, rocks, grass, etc. Experimental results show that the algorithm can obtain high-quality texture output while the image seamless processing steps are substantially reduced.
