In computer graphics, with improvement in hardware performance, more detailed production of three-dimensional (3D) models is required. However, the modeling process becomes tedious if it is carried out manually, in particular for natural objects because of their complexities. Therefore, it is important to generate content procedurally or automatically in order to efficiently produce such models. Furthermore, a purely procedural approach prevents the user from exercising total control over the outcome. The solution we proposed here is to combine the power of procedural modeling with the flexibility of manual editing. In this paper, we focus on the generation of pebble mosaics to achieve the distribution of numerous pebbles while maintaining distribution controllability. Existing research on rock modeling and digital mosaics has not focused on user-specified arrangements, whereas in this work, we present an interactive method for generating pebble mosaics. This is achieved through designing an underlying tensor field that specifies the pattern of pebble arrangement. The experimental results show that a realistic visual quality is obtained using our proposed method.
