Sample textures for spherical mapping

These textures are all produced in a manner that helps them to tesselate properly when wrapped around spheres.
Their specification includes a description of a solid block of three-dimensional texture, and a description of a surface in the block where the texture is to be carved.
Textures may also be wrapped around other solid objects.
