Abstract This paper presents an algorithm for random fields generation. The main idea of the paper is an improvement of the recursive technique presented by A. Fournier, D. Fussel and L. Carpenter in [4]. In order to ensure the continuity constraints on the boundaries of the cells generated at different stages of the algorithm, we show that it is possible to store the boundary values using a dynamic data structure. Random fields have been successfully used to model height fields or to display synthetic textures. In the second part of this paper we investigate the perspective mapping and clipping stages of random fields generation and display. At the end of the paper, some synthetic skies displayed using this technique are presented.
