Tiled Blue Noise

Blue noise textures tile well, but how well exactly? This page is a quick reference to answer that question.

I started with some blue noise textures made with the void and cluster algorithm that you can download here: http://momentsingraphics.de/?p=127

I took a 16×16, 32×32, 64×64, 256×256 and tiled each of those to make 512×512 images.

Here are the source RGBA images:




Here are the output images, where I used only the R channel of each image.

16×16:

32×32:

64×64:

128×128:

256×256:

Something interesting to note is that blue noise is supposed to tile well by nature. It is made up of high frequencies only, which means there aren’t low frequency patterns that show up and are visible to the eye.

Here’s an interesting read showing how that can be used to make textures (art) that tile better:
