In computer aided engineering (CAE) a preprocessor is a program which provides a graphical user interface (GUI) to define boundary conditions, materials, other physical properties and simulation control settings. [1] This data is used by the subsequent computer simulation. [2] Steps that are followed in Pre-Processing
Pre-processing – defining the model and environmental factors to be applied to it (typically a finite element model, but facet, voxel, and thin sheet methods are also used); Analysis solver (usually performed on high powered computers); Post-processing of results (using visualization tools).
A modern rendering of the Utah teapot, an iconic model in 3D computer graphics created by Martin Newell in 1975. Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to the study of three-dimensional computer graphics, it also ...
This effect is often simulated in computer graphics. FXAA An approximate antialiasing method performed in a post-processing step which smooths the image in screen space, guided by edge detection (contrasting with the usual supersampling approaches that require larger frame-buffers).
A post-fader output is used in order to prevent channels whose faders are at zero gain from "contaminating" the effects-return loop with hiss and hum. Mixing consoles most commonly have a group of aux-send knobs in each channel strip, or, on small mixers, a single aux-send knob per channel, where one knob corresponds to each aux-send on the board.
In signal processing, particularly digital image processing, ringing artifacts are artifacts that appear as spurious signals near sharp transitions in a signal. Visually, they appear as bands or "ghosts" near edges; audibly, they appear as "echos" near transients, particularly sounds from percussion instruments; most noticeable are the pre-echos.
General-purpose computing on graphics processing units (GPGPU, or less often GPGP) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU).
In computer graphics, the render output unit (ROP) or raster operations pipeline is a hardware component in modern graphics processing units (GPUs) and one of the final steps in the rendering process of modern graphics cards.
