Generation of Organic Textures with Controlled Anisotropy and Directionality via Packing Rectangular and Elliptical Cells

چکیده
This paper 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 allows a user to control the anisotropy of the cell geometry and the directionality of the cell arrangements. A detailed three-dimensional cell geometry is then created by adjusting a set of parameters that control the cells’ height and degree of skewing and tapering. A user can create various types of realistic looking organic textures with ease, by simply choosing a cell arrangement type, anisotropy, and directionality, along with the geometry control parameters.

Textures with Controlled Anisotropy and Directionality
Pseudo Voronoi Tessellation via Anisotropic Meshing Our tessellation technique to represent organic texture consists of three steps: (1) elliptic or rectangular particle packing; (2) anisotropic meshing by connecting the centers of the particles; and (3) Voronoi tessellation as a dual of the anisotropic mesh. Given preferred cell sizes and directionality within a geometric domain, the technique...

متن کاملHex-Dominant Mesh Generation with Directionality Control via Packing Rectangular Solid Cells
A new computational method that creates a hex-dominant mesh of an arbitrary 3D geometric domain is presented. The proposed method generates a high-quality hexdominant mesh by: (1) controlling the directionality of the output hex-dominant mesh; and (2) avoiding ill-shaped elements induced by nodes located too closely to each other. The proposed method takes a 3D geometric domain as input and cre...
