Creating tessellations

A tessellation is a type of mosaic that is made up of nonrectangular tiles. With Corel Painter, you can create a tessellation from scratch or from a clone source. A tessellation that is based on a clone source is a powerful option. The tessellation points are distributed according to the luminance of the clone source. Lighter regions receive a greater density of points, so the shapes are smaller.

You can create a tessellation from a clone source.

A finished tessellation resembles stained glass.

When creating a tessellation, Corel Painter divides the canvas into shapes, such as triangles, cracks, or pieces, which become the mosaic tiles. The shapes themselves are sets of points, connected by line segments. You can control the type of shape, the number of points, and their distribution.

You can base your Tessellation on Triangles, Cracks or Pieces.

You can also add points to a specified area to create a different effect.

Adding points in the shape of a letter. The letters appear as a swath of smaller polygons.

After creating a tessellation, the shapes appear as mosaic tiles that are given the main color and are surrounded by grout lines. You can change the color of the tiles.

You can set the tile color to white, the grout color to black, and then fill in the tessellation with color.

To create a tessellation

1	Choose Effects Esoterica Make Mosaic.

6	Choose Effects Esoterica Make Tessellation.

You can add additional points by repeating the command 500 Random Points or 500 Evenly-Spaced Points from the Options list box.

You can also add points by alternating between dragging and using an add-points commands. The points accumulate and the total number of points appears in the lower corner of the Make Tessellation dialog box.

To create a tessellation from a clone source

1	Choose File Open, and locate the file that you want to clone.

2	Choose File Quick Clone.

3	Click the Clone Color button in the Colors panel.

4	Choose Effects Esoterica Make Tessellation.

You can also adjust the grout spacing by choosing Effects Esoterica Make Mosaic, and adjusting the Grout slider.

You can continue stroking to add higher concentrations of polygons in very specific areas. This way, you can create specific patterns or shapes.

It is possible to create a huge number of points. More points mean more polygons, which increase the time it takes to convert to a mosaic. Keep this in mind to avoid overwhelming your system.

To color tessellations

1	In the Make Mosaic dialog box, select the Change Tile Color tool .

You can also base the color on the color in a clone source if you enable Clone Color in the Colors panel.
