The XOR texture, generated by xor-ing the x and y coordinate of the current pixel, is easy to create and useful for testing texture mappers. However, it’s overused and not suitable for games or art, except for fancy floor tiles. The article explores color variations and compares the XOR, AND, and OR operators. The AND texture is darker, the OR texture is brighter, and the XOR texture combined with the AND texture equals the OR texture. While creating an XOR texture is simple, it’s not recommended for most applications. Unique content includes discussing different color variations and using the XOR pattern to test a planet texture renderer.
