Isotropic

Blocks whose textures are pseudorandomly rotated around the Z-axis or mirrored along the ZY- or ZX-plane based on their position in the world are known as isotropic. The rotation or mirroring of a block depends solely on its coordinates, and not the world seed. This means that, for example, grass blocks in a 5×5 area will always have the same rotation at the same coordinates in different worlds, and this will not be changed by a player breaking or replacing them. The term isotrpic refers to the fact that a surface covered with these blocks will lock uniformly random in all directions. Since mirroring also affects the side of the block this is used on blocks that make up walls like stone. While rotation is used on blocks that make up the floor like dirt.
