3D Texture - Perlin Noise

This Perlin Noise procedural texture has been rendered into a volume data cube. It is a non-tiling 8-bit texture at 256 x 256 x 256 voxel resolution. Iso-surface meshes are also provided in PLY and STL. These textures are from an archive I made nearly a decade ago, by simply sweeping a plane through a procedural texture and rendering out the results. Here are the available formats:

RAW data 256x256x256 8-bit (zipped), 16MB uncompressed

BMP sequence 256x256x256 8-bit (zipped), 17MB uncompre
