RASTER IN R MOVIE

Though the technical details of rendering methods vary, the general challenges to overcome in producing a 2D image on a screen from a 3D representation stored in a scene file are handled by the graphics pipeline in a rendering device such as a GPU. On the inside, a renderer is a carefully engineered program based on multiple disciplines, including light physics, visual perception, mathematics, and software development. Some are integrated into larger modeling and animation packages, some are stand-alone, and some are free open-source projects. A wide variety of renderers are available for use.

Rendering has uses in architecture, video games, simulators, movie and TV visual effects, and design visualization, each employing a different balance of features and techniques. With the increasing sophistication of computer graphics since the 1970s, it has become a more distinct subject. It is the last major step in the graphics pipeline, giving models and animation their final appearance. Rendering is one of the major sub-topics of 3D computer graphics, and in practice it is always connected to the others. The term 'rendering' is also used to describe the process of calculating effects in a video editing program to produce the final video output. The term 'rendering' is analogous to the concept of an artist's impression of a scene. The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file.

The scene file contains geometry, viewpoint, texture, lighting, and shading information describing the virtual scene. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure. The resulting image is referred to as the render. Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program.
