Rendering

Rendering is the process of generating an image from a model by means of computer programs. Renders contain geometry, viewpoint, texture, lighting, and shading information as a description of a virtual scene. The term ‘rendering’ may be by analogy with an ‘artist’s rendering’ of a scene. ¬†Rendering is one of the major sub-topics of 3D computer graphics, and in practice always connected to the others. In the graphics pipeline, it is the last major step, giving the final appearance to the models and animation.

Rendering may be done slowly, as in pre-rendering, or in real time. Pre-rendering is a computationally intensive process that is typically used for movie creation, while real-time rendering is often done for 3D video games which rely on the use of graphics cards with 3D hardware accelerators.
