![]() Inside your tile add some motifs not connected, With the help of your computer, trace again your failed tile. Often your motif will be only half successful and so you will need toīut if really you get nothing satisfying, all is not lost. Of course, you will need to use a lot of the eraser before succeeding with a figurative tile. Idea of the motif to draw, trace it roughly, and adapt on it the type of best suited basic polygon and go back over the compensated deformations. When designing you can randomly choose a basic polygon and trace compensated deformations until you get a rough outline of motif. Of a fantasy nature, you have a good chance of success. If on an old decrepit wall you see figures appearing more or less You now need to appeal to the most important: your imagination. If there are vertices of odd numbers, three colors are needed. If all adjacent vertices are of even numbers, twoĬolors are sufficient. The 35 types of tessellations will be represented by 35 birds.Īll isohedral tessellations can be coloured with a minimum of two or three colors. The figures indicate the number of adjacent vertices. The structure of type 1 will be vacant because either the transformation of each of the two tiles separately (example below with concave tiles). either the transformation of the two tile set Translation as in the present case, we try the first: this gives us two tiles. When we have several kinds of transformations before Shephard in their book Tilings and Patterns. The symmetry group used is that of the International Tables for x-ray crystallography. Designation R3 R3 R3 R3 R3 R3:Īnd its transformations before translations The base polygon of the 'madman' is a regular hexagon. We will refer it by R3S R3S R3S R3S because the sides are both of 3 rotations and symmetries: The one of the duck is a rhomb with two angles of 120°.Now here are the designations of basic polygons for: ![]() We will designate it by the isometries of the sides, that is to say R2 R4 R4:
