This example, from the homepage, has isohedral type IH61. Only a single edge of the square needs to be deformed. The other 3 edges are rotations of the base edge. You can download the project file here: bird_ih61.tis . The following zip file contains the project file and the 4 image files: bird_ih61.zip . Note that you must replace the image file names at menu option Tessellation / Load Multi Background by the locations of the unpacked images. |

This example of isohedral type IH7 shows a tessellation with photographic imagery. The base tile is a non-regular hexagon with 3 pairs of adjacent sides, which have rotational symmetry with a rotation angle between them of 120 degrees. You can download the project file and the 3 image files: lion_ih7.zip . Note that you must replace the image file names at menu option Tessellation / Load Multi Background by the file locations of the unzipped images. |

These tessellations are examples of the Four-armed-mirror spiral, made with 1 background image, and with 2 background images. You can download the project file and the image files: nose_spm1.zip, nose_spm23.zip. Note that you must replace the image file names at menu option Tessellation / Load (Multi) Background by the file locations of the unzipped images. |

At day 1 of the release of Tissellator Michael
J. Maloney installed the program, completed the
registration, mastered the program, and created a multi background
tessellation. More work of Michael can be found here. |

| A spiral of similar tiles, made from deformed hexagons obeying isohedral type IH1. This picture has been constructed using the overlay technique in Tissellator: load the dog as background image, then fit the outline to the dog’s face, and generate the fractal. |  |
| This circle tessellation has
isohedral type IH3. Thanks to the glide reflection the mandarin fish
“swim” in clockwise direction and counter-clockwise direction. The 4
images show the tessellation rendered with 1 tile, 2 tiles, 3 tiles
and 4 tiles. The color scheme feature in Tissellator allows the
designer to choose the wanted color pattern of images. Note that the
number of images is not limited to four, but unlimited. The color scheme for the image of 2 tiles is 0 0 0 0 1 1, for 3 tiles it is 0 1 2 0 2 2, and for 4 tiles it is 0 1 1 0 2 2 . Click on the image for an enlargement. |

| The black and white fish in M.C.
Escher’s artwork no 73
have been reworked in four colors. The tessellation of isohedral
type 41 has been transformed into a multi spiral with 3 arms. Click on the image for an animation. |
 |
| This image has been constructed in several steps. A tessellation of 4 fish has been transformed with Tissellator's Poly Spiral transformation. (In such a transformation the points in the complex plane are relocated with a tangent function.) The result is made repetitive and again transformed with the Poly Spiral transformation. |  |

This tessellation is based on a pentagram with isohedral type IH21. It shows how the red and blue points can be moved outside the border of the original pentagram, see image on the left (click for enlargement). Then, firstly a tessellation has been made using 6 background images, each having its own color. Secondly, the menu option "Transform / Tessellated image / Hyperbolic Tessellation" has been executed to generate the filled circle on the right. M.C. Escher has made 4 such images, known as Circle Limit.Tissellator makes it very easy to create such an hyperbolic image. |

An Hyperbolic Tessellation image can be created with circle inversion. This means that pixels outside the circle are filled with their counterparts inside the circle. The circle boundary acts as a mirror. This algorithm has been applied to a hyperbolic image, that was created in June 2020, far before Tissellator existed. Just load a background image and execute the menu option "Transform / Background image / Circle Inversion Background ". |

This type of image has been discovered by Ludwig Danzer. It is a
Penrose type aperiodic image, but now with 7 orientations instead
of 5. See the Tilings Encyclopedia for more details. The
image looks chaotic as shown at the left, but at a bigger scale
shown at the right there is locally 7-fold symmetry. An animation
zooming in and out can be found here. |

| This is a Penrose P3 tessellation with 180 degrees rotation symmetry around the center of the image. Such an tessellation with deformed edges is only possible when the edge at the rotation point is symmetric. |  |
| This Vierstein image is made of the 4 deformed metatiles of the already famous aperiodic einstein monotile discovered by David Smith e.a.. Neighbour tiles of the same color occur only at the fylfot metatiles. The image requires 4 iterations of the substitution method. |  |
