Simple SCAN Expressions
Simple SCAN Expressions produce homogeneous patterns . For example a simple expression is R2#B4 generating the following 8x8 pattern.Graphical output: Complex SCAN Expressions
Complex SCAN Expressions produce more complex SCAN Patterns. Usually complex Scan Patterns, contrary to the simple ones, may be not homogeneous. An example of a complex pattern is the third class Cilbert curve of Peano family of space filling curves. The corespondign SCAN expression describes the basic template generating the Hilbert curve and the transformations that must be applied on it.
