The conception and algorithm simulation of lattice digital filter in electronics are transplanted into optical filter, with a novice algorithm to resolve optical lattice array concrete parameter.

These filters are designed by using the concept of wave digital lattice filter and by making use of a novel approximate transformation method for wide band bandpass filters.

The facade is composed by lattice patterns alternated with vertical landscapes that filter the strong tropical sunlight into a pleasant play of light and shadow on the textured walls.
