Software design pattern. In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code . Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase ...
Moiré pattern. A moiré pattern, formed by two sets of parallel lines, one set inclined at an angle of 5° to the other. The fine lines that make up the sky in this image create moiré patterns when shown at some resolutions for the same reason that photographs of televisions exhibit moiré patterns: the lines are not absolutely level ...
Design Patterns: Elements of Reusable Object-Oriented Software (1994) is a software engineering book describing software design patterns. The book was written by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, with a foreword by Grady Booch. The book is divided into two parts, with the first two chapters exploring the capabilities ...
A design pattern is the re-usable form of a solution to a design problem. The idea was introduced by the architect Christopher Alexander [1] and has been adapted for various other disciplines, particularly software engineering .
Contrast fabric is a sewing term that refers to a fabric piece or embellishment made from a different fabric than the main fabric. The term 'contrast fabric' is used in contrast to the term self-fabric . Contrast fabric is used in certain pattern pieces such as facings and linings to produce design details that stand out from the rest of the ...
The prototype pattern is a creational design pattern in software development. It is used when the types of objects to create is determined by a prototypical instance, which is cloned to produce new objects. This pattern is used to avoid subclasses of an object creator in the client application, like the factory method pattern does, and to avoid ...
Decorator pattern. In object-oriented programming, the decorator pattern is a design pattern that allows behavior to be added to an individual object, dynamically, without affecting the behavior of other instances of the same class. [1] The decorator pattern is often useful for adhering to the Single Responsibility Principle, as it allows ...
While digital patterns are becoming widespread, critics maintain that the pixellated look is a question of fashion rather than function. The design process involves trading-off different factors, including colour, contrast, and overall disruptive effect. A failure to consider all elements of pattern design tends to result in poor results.
