Pre-rendering is the process in which video footage is not rendered in real-time by the hardware that is outputting or playing back the video. Instead, the video is a recording of footage that was previously rendered on different equipment (typically one that is more powerful than the hardware used for playback).
Previsualization (also known as previsualisation, previs, previz, pre-rendering, preview or wireframe windows) is the visualizing of scenes or sequences in a movie before filming. It is a concept used in other creative arts, including animation, performing arts, video game design, and still photography.
Rendering can be split into two main categories: real-time rendering (also known as online rendering), and pre-rendering (also called offline rendering). Real-time rendering is used to interactively render a scene, like in 3D computer games, and generally each frame must be rendered in a few milliseconds. Offline rendering is used to create ...
A distinction is made between real-time rendering, in which images are generated and displayed immediately (ideally fast enough to give the impression of motion or animation), and offline rendering (sometimes called pre-rendering) in which images, or film or video frames, are generated for later viewing. Offline rendering can use a slower and ...
Re-rendering a game's graphics is not always possible, however; as was the case in 2012, when Beamdog remade BioWare's Baldur's Gate (1998). Beamdog were lacking the original developers' creative art assets (the original data was lost in a flood [5]) and opted for simple 2D graphics scaling with "smoothing", without re-rendering the game's ...
Cutscenes often feature "on the fly" rendering, using the gameplay graphics to create scripted events. Cutscenes can also be pre-rendered computer graphics streamed from a video file. Pre-made videos used in video games (either during cutscenes or during the gameplay itself) are referred to as "full-motion videos" or "FMVs". Cutscenes can also ...
Pre-integrated volume rendering [15] is a method that can reduce sampling artifacts by pre-computing much of the required data. It is especially useful in hardware-accelerated applications [16] [17] because it improves quality without a large performance impact. Unlike most other optimizations, this does not skip voxels.
Pre-flight is an automatic scan of the document using the printers pre-defined profile to find errors before submitting. [ 3 ] Raster Image Processor (RIP) is the software/hardware that processes the print-ready files into a rasterized format that the printer can understand.
