It is clear that each of these boxes is a tileable section of its respective pattern. I have shown these two boxes in the diagram but only one pattern is shown in each.

To see this, consider the figure below which shows two overlapping stripe patterns (orange and blue):Įach rotated stripe pattern is individually tileable with two box sizes shown in the diagram: the blue pattern is (h_h, w_h) and the orange pattern is (h_w, w_w). There are two orthogonal directions (along w and h lines) in which the pattern repeats.

Since we want acute angles, if you are rotating in the other direction, then the diagram above looks like this: The angle of rotation is the acute angle formed by the w line with the horizontal: The basic unrotated texel is highlighted and has width w and height h. The image below shows a rotated texture that was formed by tiling the original unrotated pattern and then rotating the resulting mosaic.

It might be unclear but full understanding is not necessary to use the technique. There is a bit of geometry involved here. It is therefore applicable to Photoshop or any other paint program.

This tutorial works out how to make it tileable.Īlthough this tutorial is written for the GIMP, there are actually very few GIMP-specific instructions. The rotated texture is trickier to tile and you can see that the pattern at each edge of the image will be hard to match up with the opposite edge. Tiling is easy for the unrotated image, all you need to do is make an image that contains exactly one of the repeating texture elements. Shown below is a generic tileable pattern where I highlighted the repeating texture element (texel), along with a rotated version of the same texture. As with the previous tutorial, the problem is to take a tileable texture and rotate it and still keep the rotated texture tileable as part of a web page background or something like that. This is a little more complicated than the stripes pattern and requires a bit more math. F ollowing on my tutorial on how to make tileable stripe patterns, this is a tutorial on how to make tileable rotated versions of any tileable pattern or texture (for example, a rotated checkerboard, a tilted grid or an angled weave pattern).
