Blue Noise Texture Generator

Features

• Uses Robert Ulichney's void-and-cluster algorithm.
• Generation of Texture2D, Texture2DArray and Texture3D types.
• Supports R, RG, RGB, and RGBA textures in a number of data formats.
• Ability to create spatiotemporal 3D blue noise.
• Energy function is seperately configurable for each axis.
• Steepness parameter allows for more variety in the output, including textures with green noise characteristics.
• Option to make use of Unity's compute shaders to boost performance.
• Features a 2D graph of the energy curve for each axis to assist in visualisation.
• Can export the result directly as a Unity asset, or as an image file on disk.
• Preview the uncompressed size of the texture in memory before creation.

Performance

With compute shaders enabled, it takes ~12 minutes to generate a 1024x1024 single-channel blue noise texture. In practice a 256x256 texture is enough for most applications, and can be generated in ~3 seconds. (Benchmark Platform: NVIDIA Quadro P3200)
