<p>This article presents a computational method for generating organic textures. The method first tessellates a region into a set of pseudo-Voronoi polygons using a particle model and then generates the detailed geometry of each of the polygons using Loop's subdivision surface with fractal noise. Unlike previous particle models-which are designed for creating hexagonal cell arrangements-this particle model can also create rectangular cell arrangements, often observed in organic textures. In either cell arrangement, the method lets a user control the anisotropy of the cell geometry and the directionality of the cell arrangements. A detailed 3D cell geometry is then created by adjusting a set of parameters that controls the cells' height and degree of skewing and tapering. A user can create various types of realistic looking organic textures by choosing a cell arrangement type, anisotropy, and directionality, along with the geometry control parameters.</p>
