In this tutorial we will create a mosaic consisting of polygons. Free Scriptographer plug-in and our imagination will help us in this unsophisticated task. Have fun and enjoy our new Adobe Illustrator tutorial!
Creating vector polygons
To create a polygonal mosaic, we need a reference image. In this tutorial I will be using the Red Apple from Shutterstock. Paste the image into the current document (File > Place ...), then click on the Embed button in the Control panel (Please do not skip this step).
Lock the image in the Layers panel, in order to make sure we do not move it in the further work.
Begin to create polygons. Polygons can be polygonal shapes which sides are straight-line segments. Turn on the stroke of black color and choose white color as the color of the fill. Set 50% opacity in the Transparency panel. Create the first polygon at the place of glare on the apple.
For further work set the following settings. Turn off the New Art Has Basic Appearance option in the flу-out menu of Appearance panel.
This will allow us to create new polygons with the same opacity as the first polygon or last selected one. Turn on the Smart Guides option (View > Smart Guides).
This will allow combining points of adjacent polygons exactly. With the exact combination of the tool with the point, there will appear "anchor" inscription.
Create new polygons, so that there are no gaps in between.
It is difficult to give advice on the shape and size of the polygons. Everything depends on the shape of the object and the distribution of colors on its surface. However, try to place the polygons so that their edges reproduced object volume and the shape of the shadows and highlights. Yes, it's not easy. Here you need a little more practice. Frankly speaking, this is the first experience for me. I hope that you'll do much better.
Anyway, you can edit the achieved result.
Now create polygons over the shapes of a leaf and an apple stalk.
Select all the created polygons, then turn off the stroke and set 100% opacity for them.
Though I tried to work neatly, but still some defects could not be avoided. For exact points combining of the adjacent polygons select them with the help of the Lasso Tool (Q).
Now align them vertically and horizontally with the help of the Align panel.
If you missed some polygons, just finish drawing them. After elimination of all the defects polygons are ready to be colored.
To color polygons, we will be using free Scriptographer plug-in. You can download and read the instructions on how to install it following links - Download and Installation Instructions. Open its Main Palette (Window > Scriptographer > Show Main Palette).
Now unlock the image of an apple in the Layers panel. Select it, and all of the polygons. In the Main Palette choose the script named Colorizer, then click on the Play button.
After a few seconds all the vector objects will be colored in the colors of the bitmap image.
You can edit the achieved result. For example, using the Lasso Tool (Q) you can select the points of adjacent polygons and move them in the direction you decide.
You can make some fragments in details. To do this, with the Scissors Tool (C) cut the necessary polygons.
Do not forget to close the cut paths. To cut polygons you can also use the Knife Tool. In order to make this tool cut along a straight line, hold down the Option / Alt key.
After all the changes, select all the polygons and lower image, then run Colorizer script again.
You may not be satisfied with the color of some polygons. No problem. Just select it and recolor it with the help of the Color panel.
If you turn off the visibility of the reference image, we can notice thin gaps between the polygons.
Do not worry about it. When you save the image as a bitmap, these cracks will not be visible.
Automatic generation of polygons
For automatic generation of polygons you can use the Grid generator script. Place it to the folder where Scriptographer scripts are. After that, it will appear in the Main Palette.
After running the script there opens a panel in which you can choose the type of grid and specify the number of columns and rows.
When the grid is generated, select any reference image and all the vector objects, then run Colorizer script.

THE LAW OF THE ONE by Hassmework
Advanced readers may notice that there are scripts that allow you to generate random polygons similar to Delaunay Raster. I will answer that such scripts are very difficult to manage, and the finish result is almost not editable. Besides, you are not immune from the sudden Adobe Illustrator crash. Another thing, when you are working with simple vector objects, which editing does not cause any problems. Wish you more success in your art!
Scriptographer help: I select the image layer and all paths above it but it gives me an error and says I need to select an image... I've tried the paths in separate layers and also putting the paths directly on top of the image.
