Design is the most important stage in the development of software systems; further development and further development of the project depends on this stage. The cycle of the program (system):
- formulation of the problem;
- programming (coding);
- testing and debugging;
- industrial operation and maintenance;
- refusal to operate.
At first glance, the main thing in writing a software system is programming (coding), however, in fact, design is a much more important process.
With a competent design of a software system, its development is much easier. When designing, it is necessary to take into account the further development of the system, provide for the possibility of expanding the functionality, and take into account all factors significant for the functioning of the system. If design errors occur, further development may not be possible. It is not necessary to design everything to the smallest detail – this will only confuse the customer. It is important to come up with and think over the structure of the solution of only the main problems, the secondary ones – only if they are difficult enough to understand.
Brevity, unambiguity, and relative simplicity are the design quality criteria. There are many tools for the visual presentation of the design result. For procedural programming, these can be function call trees and/or algorithms depicted in the form of block diagrams. Object-oriented programming uses the graphical representation language UML (English Unified Modeling Language). Modeling (design) in UML consists of three main stages, building three main diagrams: use case diagrams, class diagrams and sequence diagrams. UML is a widely used modeling language because most modern programming languages are object-oriented. There are a large number of special case tools that use UML notations to visualize models of the system being developed in the form of various diagrams.
Sometimes, the operation of a software system can be thought of as a 3D model, especially when the system consists of rather complex parts. A three-dimensional graphical representation of a model of any complexity is most fully and adequately perceived by a person. Such visualization will not interfere with the development of rather complex games (3D games) or 3d architectural modeling, since any other visualization will extremely poorly reveal all the details of the graphics. The game process itself can be called a dynamically changing 3D model, so it is quite logical to simulate an example of a game moment when designing. Here the advantages are very obvious because otherwise, it is difficult to imagine what to do at the stage of program coding (at the design stage, it is necessary to decide how exactly this or that function will be implemented in the program, this is precisely the main point of design).
Obviously, 3D visualization should be used not only when designing games, but also when designing any application that uses 3D graphics, be it a three-dimensional graphics editor, or a program for creating a model of the interior of a room. It is always easier to understand a three-dimensional model than something more abstract, therefore, the designer can always show the model to the customer so that he can express his wishes.
The disadvantages of 3D visualization include a long design time. This is a rather serious drawback, because if one simple 3D object is used in the software system, then there is no need to perform 3D visualization, especially if this object is of secondary importance.
You need to understand that 3D visualization can be different, and when designing, most often there is no need to visualize everything to the smallest detail (with rare exceptions), since visualization can reveal serious flaws that it is desirable to identify and eliminate before starting programming the system in order to save a significant amount time and money. So, for example, with 3D visualization of the Boeing 777 aircraft, it was possible to save almost 15% of the funds spent on production.
