This Smoke 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. I have also included PNG codec AVI versions, one of which "fades" at the edges (for making surface that don't end abruptly). 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 uncompressed

PNG codec AVI 256x256x256

PNG codec AVI 256x256x256 (faded 16vx at edges)

PLY isosurface mesh 2.0M polygons

STL isosurface mesh (reduced) 990K polygons
