Computer-generated imagery (CGI videos)

Computer-generated imagery refers to the way computer graphics are applied in the creation and contribution of art images, films, printed media, TV programs, simulators and vfx videos. CGI is widely used to refer to three-dimensional computer graphics that are used in the creation of scenes and special effects such as 3D-animation and 3D-images in television or films. A person working at home can as well make such editions by use of programs like iMovie and movie maker.
With advanced technology, video games now employ real-time graphics, by a computer, sometimes referred to by the term CGI. This may at some point include 3D rendered introductory movies or cut scenes that are typically CGI applications. CGI is therefore highly recommended for any visual effects due to its high quality of output, the ability to render effects that are easily controllable as compared to others that are based on physical processes like hiring more people to showcase crowd scenes. It also allows one to create images that are not achievable by use of another technology. CGI is also considered a cheaper way of producing content because it gives any single artists an opportunity to produce their content without using actors, expensive pieces or props. Virtual cinematography started in 1990s as a result of CGI evolution.
CGI videos are widely used not only in video and cinematography industries but also in many other field. This paragraph discusses the several areas in which CGI is applied and how effective it is.

Static images- still images such as natural landscapes are also created by use of computer algorithms. An example of this natural landscapes is the fractal landscapes. Fractal algorithms are algorithms that are used in creating topographical maps that have varying altitudes. Other fractals used include the fault fractal and plasma fractal. Some specific models are also used to represent the way stone undergo chemical weathering to model erosion as well as producing aged appearance in certain stone surfaces.
Architectural scenes- architects use facilities offered to them by firms that deal with computer graphics to come up with 3D models for their customers and for the builders. This models are highly preferred due to the accuracy they render as compared to traditional drawings. With these models, an architect is able to envision a space and do walk-throughs in a tacit manner. One can also see the effect of sunlight on the building at day time. Companies may also use this technology to create their corporate videos.
Anatomical models- this type of models are often used for operational purposes and for giving instructions. In CT scans, 3D models are automatically acquired from several x-rays, which In turn gives a CGI. In treating diseases that affect the heart, a model that looks like a coronary opening is extracted from several CT scans, as that will help plan for the procedure.
Generation of cloth images and skins- functional realism, physical realism and photo realism are the levels in the realism of rendering the skin of a human being. Clothes are also made in a way that they can automatically naturally.
