The translation of flat images into spatial ones greatly facilitated the applied fields of science. Thanks to this, a number of tasks were accomplished:

  • Visually present the details. To read the diagrams, certain skills and an analytical mindset are required. After processing, understand what is drawn in the picture, everyone can.
  • To model designs. In the two-dimensional drawing of complex geometric shapes, many errors arise in the docking of individual elements. They can cause additional costs and alterations at the stage of manufacturing products.
  • To coordinate design decisions. Due to a visual representation, it became easier to act on related specialists who should work through their sections within the same computer file.

To meet these needs, SGI has created OpenGL libraries. They have become a standard in the field and are actively spreading in our time. Developments are an innovative interface for hardware that interacts with graphics. The greatest productivity in encoding information can be achieved with the use of accelerators. The accelerator is a part of the computer that takes over part of the data stream and unloads the processor.

Initially, the algorithms were developed by the company for its own needs on the Iris workstations. Later they were integrated into all modern platforms. Today they are considered the most universal and productive.

The principle of operation is based on the use of data libraries, which are implemented in the programming language C. This allows you to work with an unlimited number of tasks. This principle complicates the interaction with simple elements and standard forms. But for modern developments this is a big plus. They can create their own objects, used in the area covered by the software without any restrictions.

  • Fortran;
  • Python;
  • Java;
  • C++;
  • Delphi.

For individual fields of science and industry, their libraries of the simplest details and forms have been developed. They make it possible to make simple visualization programs.

Microsoft has created for its needs an analogue – a DirectX application. It operates only in Windows operating systems and is actively used to develop multimedia add-ins and game engines. This development has not found its application in the field of applied sciences and software for design. The reason for this was a narrow focus in development.

Biased rendering

They are based on the assumptions that an application can make in the process of calculating pixels. The work is carried out according to certain criteria. The user specifies the specific values ​​that serve as the end points for the system. On this principle, there are:

RenderZone;
Artisan;
V-Ray;
FinalRender;
Mental-ray.
Orientation to the operator allows you to implement any task – even those that run counter to the laws of physics. It is possible to ignore surface structures, the classical direction of chiaroscuro and other effects. The negative side of these innovations is that you have to enter all the parameters yourself.

Unbiased rendering

The basis is the negation of assumptions. The process of graphical computation is performed according to given physical patterns. Detailing is brought to the level of realism that will be acceptable for the user. The following engines are used for this:

Fryrender;
Maxwell;
Iray.
They are used to create programs for visualization and rendering of 3d models, which provide a better detail of the final image. They provide an opportunity to achieve quality comparable to photography. These pixel calculation technologies are widely used in animation and rendering of special effects for films.

Both variants of the listed algorithms are used in software for design and design. They allow you to do different levels of drawing for the same objects with the given parameters. One product usually includes several modules. Due to this, the user can save the final file in different formats and degrees of realism.

Programs run as stand alone applications or are used as integrated components.
