Architectural scenes Ī computer-generated image featuring a house at sunset, made in Blender Many specific techniques been researched and developed to produce highly focused computer-generated effects - e.g., the use of specific models to represent the chemical weathering of stones to model erosion and produce an "aged appearance" for a given stone-based surface.
Some typical, easy-to-program fractals used in CGI are the plasma fractal and the more dramatic fault fractal. Thus a topographical map with varying levels of height can be created using relatively straightforward fractal algorithms. The creation of a Brownian surface may be achieved not only by adding noise as new nodes are created but by adding additional noise at multiple levels of the mesh. For instance, the algorithm may start with a large triangle, then recursively zoom in by dividing it into four smaller Sierpinski triangles, then interpolate the height of each point from its nearest neighbors. A simple way to generate fractal surfaces is to use an extension of the triangular mesh method, relying on the construction of some special case of a de Rham curve, e.g. Not only do animated images form part of computer-generated imagery natural looking landscapes (such as fractal landscapes) are also generated via computer algorithms. Availability of CGI software and increased computer speeds have allowed individual artists and small companies to produce professional-grade films, games, and fine art from their home computers. The evolution of CGI led to the emergence of virtual cinematography in the 1990s, where the vision of the simulated camera is not constrained by the laws of physics. The first music video to use CGI was Dire Straits' award-winning " Money for Nothing" (1985), whose success was instrumental in giving the process mainstream exposure. Other early films that incorporated CGI include Star Wars: Episode IV (1977), Tron (1982), Golgo 13: The Professional (1983), The Last Starfighter (1984), Young Sherlock Holmes (1985) and Flight of the Navigator (1986). The first feature film to make use of CGI was the 1973 film Westworld. The application of CGI for creating/improving animations is called computer animation, or CGI animation. CGI both refers to 2D computer graphics and (more frequently) 3D computer graphics with the purpose of designing characters, virtual worlds, or scenes and special effects (in films, television programs, commercials, etc.). Computer-generated imagery ( CGI) is a specific technology or application of computer graphics for creating or improving images in art, printed media, simulators, videos and video games.
