The moiré is a visual interference; a geometric distortion effect caused by the interaction of two frame patterns, located one above the other. The result is a new pattern with a somewhat peculiar visual effect. This visual effect was called moiré or moiré. The name of the French term was borrowed, which refers to a type of silk fabric that has a similar visual effect due to its composition based on line patterns.
