Since design patterns are invading the interior design market as they are widely applied on wallpapers, carpets, fabric textiles, three-dimensional lanterns and tableware, rule-based computational design became a major research area. It has been explored from many perspectives.
A research by Ulu and S¸ener (2009) used the 10-sided polygon, decagon, tie and bow-tie subshapes in creating geometric patterns in Islamic art. Two design templates were developed to generate Islamic patterns using a shape grammar model. The model should be applied to a software to get easier and faster results.
An Islamic star pattern is an arrangement of lines that forms different shapes. A research by Kaplan (2000) examined the characteristics of Islamic patterns: stars and rosettes.
A research by C¸olakoglu et al. (2008) gave formal descriptions of eight-pointed Islamic star pattern that showed a variety of geometrical structures. “PatGen” software was developed to produce Islamic patterns, which was based on tiling stars and rosettes in a plane. Other patterns are investigated in (Kaplan, 2005) and (Kaplan & Salesin, 2004).
Patil (2002) proposed a geometric model for two-dimensional patterns. Patterns were described using a hierarchical tree model, which defines a pattern in terms of shapes. The model was implemented as a Shape Description Format that allows users to describe shapes in terms of curves.
A software named “pattern” was implemented that reads in a shape description, builds a tree of shapes and renders a pattern. The model does not take into account the space occupied by shapes. If some shapes overlap, the model does not detect the overlap.
