“…The Voronoi diagram defined by mathematician Voronoi in the early twentieth century received attention as a very useful diagram that can explain phenomena and structures in nature. It is used in the form generation process of architecture, jewelry, and industrial design, as well as in various other fields such as computer engineering, meteorology, geology, topography, archeology, medical science, molecular chemistry, and ecology (Kim and Kim, 2006;Zheng et al, 2011;Fantini et al, 2016). The Voronoi diagram is an outcome of specific space division whereby, starting from a discontinuous point referred to as the "site, " all cells are comprised of points that are closer to the generation seed (Lautensack, 2008;Malinauskas, 2008;Phillips, 2014).…”

This study found that clothing, combined with digital technology, can be a wearable computer that adapts to environmental change and increases biological limits, as well as an emotional space to which art and design are applied, and that promotes mutual communication. A user-friendly interface is proposed for those pursuing a new artistic experience by building a conceptual algorithm for biomorphic clothing sculpture modeling that can be used to create generative designs simply by entering moderated mediator variables. Biomorphic clothing sculpture refers to clothing that is inspired by life in nature and modeled in three dimensions. As the human body and buildings are 3D forms, the parametric design method used frequently in architecture is implemented here and used as a tool to explore attributes and representations of 3D modeling in clothing sculpture design. On the basis of a literature review, this study presents knowledge-based data for biomorphic clothing sculpture that can predict generative design outcomes, and through a case study, identifies the mediator variables and attributes of the parametric process related to biomorphic clothing sculpture modeling. The knowledge-based data on biomorphic clothing sculpture and biomorphic clothing sculpture modeling mediator variables discovered during the research are applied to the 3D modeling process as visual data and presented as the conceptual interface of biomorphic clothing sculpture.

“…These research results indicate that the characteristics of columnar jointed rock mass are very complex with anisotropic and nonlinear properties. Most of the modelling methods of columnar jointed rock mass use the program developed by Zheng et al [14]; however, this method has some shortcomings, such as a low efficiency and immutable columnar shapes, as pointed out in Reference [20]. The objective of this paper is to overcome these shortcomings in the generation of columnar joints in rock mass.…”

“…Meng systematically analyzed the anisotropic properties of columnar jointed basalt using analytical and numerical methods [13]. Zheng et al proposed a 3-D modeling method for columnar basalt using random Voronoi tessellation [14]. In References [15][16][17], 2-D and 3-D discrete element simulation methods of columnar are implemented, and the representative elementary volume scale and equivalent mechanical parameters are obtained.…”

Generation of Numerical Models of Anisotropic Columnar Jointed Rock Mass Using Modified Centroidal Voronoi Diagrams

et al. 2018

A columnar joint network is a natural fracture pattern with high symmetry, which leads to the anisotropy mechanical property of columnar basalt. For a better understanding the mechanical behavior, a novel modeling method for columnar jointed rock mass through field investigation is proposed in this paper. Natural columnar jointed networks lies between random and centroidal Voronoi tessellations. This heterogeneity of columnar cells in shape and area can be represented using the coefficient of variation, which can be easily estimated. Using the bisection method, a modified Lloyd’s algorithm is proposed to generate a Voronoi diagram with a specified coefficient of variation. Modelling of the columnar jointed rock mass using six parameters is then presented. A case study of columnar basalt at Baihetan Dam is performed to demonstrate the feasibility of this method. The results show that this method is applicable in the modeling of columnar jointed rock mass as well as similar polycrystalline materials.
