A Simple Algorithm for Constructing Perfect Monolinear Sona Tree Drawings, and its Application to Visual Art Education
نویسندگان
چکیده
The traditional sona drawing art of Angola is compared from the structural point of view to similar geometric arts found in other parts of the world. A simple algorithm is proposed for constructing a sub-class of sona drawings, called perfect monolinear sona drawings, on a given set of points in the plane, that exhibit the topological structure of a tree. The application of the tree sona drawings obtained with this algorithm to the visual arts and Discipline Based Art Education is illustrated. Key-Words: Sona drawings, monolinear drawings, minimum spanning trees, dual tree, algorithms, kolam art, sanddrawings, Celtic knots, visual arts, art education

Comparative analysis of mythological role of Layla in poems of Nezami and Jami and its representation in Iranian painting
In Iranian paintings, both signs of physical beauty and feminine spiritual beauty have emerged with applications of artistic and design principles. In harmony with literature, painters have attempted to show the concept of women with good outward and inward qualities, and finally to present a beautiful and chaste image of them in their paintings. According to Iranian literature and paintings, a...
متن کاملArea-eecient Upward Tree Drawings
Rooted trees are usually drawn planar and upward , i.e., without crossings and with parents placed above their children. In this paper we investigate the area requirement of planar upward drawings of trees, and present optimal algorithms for constructing such drawings.
متن کاملUpward Tree Drawings with Optimal
Rooted trees are usually drawn planar and upward, i.e., without crossings and without any parent placed below its child. In this paper we investigate the area requirement of planar upward drawings of rooted trees. We give tight upper and lower bounds on the area of various types of drawings, and provide linear-time algorithms for constructing optimal area drawings. Let T be a bounded-degree roo...
متن کاملFast Detection and Display of Symmetry in Trees
The automatic construction of good drawings of abstract graphs is a problem of practical importance. Displaying symmetry appears as one of the main criteria for achieving goodness. An expression is obtained for the maximum number of axial symmetries of a tree which can be simultaneously displayed in a single drawing, and an algorithm is presented for constructing such a maximally-symmetric draw...
متن کاملStrip Symmetry Groups of African Sona Designs
The sona drawings of the Chokwe people of Angola/Congo are continuous one-line drawings, generally made in the sand, that are often used to build highly symmetric one-line drawings. A large class of these drawings can be viewed as a form of “mirror curves,” visualizable as a curve bouncing through an arrangement of dots, bouncing off “mirrors” placed between some of the dots, and leaving a symm...
