Rendering (rendering) (rendering) — - the process of creating and displaying scenes on its description in the database.

Render ( r ender) — a program that performs the conversion of digital data describing three-dimensional scenes from the format in which they were created or stored in the output format on the screen or in a different format of the user.

Realistic rendering (realistic rendering) — machinery , creating a " realistic" color video , which takes into account , in particular , the effects of radiation , reflection and refraction of light is part of computer animation. Means of implementing realistic rendering is a computer simulation using conventional art tools and techniques (X- methods or Natural Media), as if " without using a computer ." These funds provide for the creation and modification of light sources , shading the surface of objects , imposing on them the desired texture (eg , different kinds of roughness ) , surface distortion effects make translucent objects.

No photorealistic (NPR, Non-photorealistic rendering) — a type of computer image generation without putting aim to achieve photorealism ; usually means computer simulations of various art tools and techniques. Types nefotorealisticheskuyu rendering : a picturesque three-dimensional (3d) rendering (Painterly Rendering), a picturesque postprocessing, imitation art tools and techniques ( sketches, drawings and pen engravings) , automatic generation of technical drawing , alternative perspective , the transfer of stylized movement.

Scenic rendering (Painterly Rendering) — a term used for computer graphic work , imitating the work performed manually. Most programs for the implementation of pictorial rendering oriented processing visual material , pre-prepared by other means. Such programs are composed of special algorithms and tools that allow you to enter various effects and to make their setting ( including shading , shading , contouring , shading) .

3D-Cel — graphics, simulating traditional shape contour down and fill color cartoon .

3D-Cartoon — Cartoon - three-dimensional graphics using a specially created three-dimensional models to create animations .

AFR (Alternate Frame Rendering) — technology that provides high-speed output video to the screen. In early versions of the technology offered by ATI - 3Dfx to accelerate the transition from one frame to the next image was formed two lines of video amplifier . In order to reduce the cost of the video system and improve its efficiency firm nVIDIA does not divide the image line by line , and offers a technique in which the driver selects one of three modes : compatible , AFR or SFR.

SLI (Scalable Link Interface) — Technology company nVidia, proposed in 2004 , to double the speed of processing of three-dimensional (3D) images to a PC put two cards. Combining them into a system for collaborative work is done by alternating the flow processing : even lines from one processor , odd - from another.

CrossFire — technology to increase processing performance of three-dimensional (3D) images, designed by Canadian company ATI. CrossFire works with standard GPU, which are complemented by specialized programmable processor - Composing Engine.
