A method for generating pavement textures using the square packing technique

This paper presents a method for generating pavement textures using the square packing technique. A pattern of packed square cells for a given area is generated by performing particle simulation with proximity-based forces. The pavement texture is then obtained by generating a stone shape for each cell with the subdivision surface method and then applying fractal noise to create a detailed surface geometry. In this method, the boundary shape of the pavement and the average size of the pavement stones are specified as input geometric data, along with attribute data such as the roughness, color, and optical attributes of the stones. The proposed method automatically generates a visually realistic pavement texture for an arbitrarily shaped pavement with much lower computational cost than previous methods.
