In 3D computer graphics, hidden-surface determination (also known as shown-surface determination, hidden-surface removal (HSR), occlusion culling (OC) or visible-surface determination (VSD)) is the process of identifying what surfaces and parts of surfaces can be seen from a particular viewing angle.
Graphic software programs, which can be broadly grouped into vector graphics editors, raster graphics editors, and 3D modelers, are the primary tools with which a user may manipulate, enhance, and transform images. Many image editing programs are also used to render or create computer art from scratch.
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. [citation needed] The resulting image is referred to as a rendering. Multiple models can be defined in a scene file containing objects in a strictly defined language or data structure.
General-purpose computing on graphics processing units. 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 ...
DrawPlus. DrawPlus was a 2D vector graphics editor and animation software developed by the UK-based software company Serif, also responsible for PhotoPlus, PagePlus, WebPlus, Digital Scrapbook Artist, Affinity Designer, Affinity Photo and other titles. [1] Serif have ceased development of DrawPlus in order to focus on its successor, Affinity ...
Back-face culling. On the left a model without BFC; on the right the same model with BFC: back-faces are removed. In computer graphics, back-face culling determines whether a polygon is drawn. It is a step in the graphical pipeline that tests whether the points in the polygon appear in clockwise or counter-clockwise order when projected onto ...
GNU Image Manipulation Program, commonly known by its acronym GIMP ( / ɡɪmp / GHIMP ), is a free and open-source raster graphics editor [4] used for image manipulation (retouching) and image editing, free-form drawing, transcoding between different image file formats, and more specialized tasks. It is extensible by means of plugins, and ...
Foreground detection is one of the major tasks in the field of computer vision and image processing whose aim is to detect changes in image sequences. Background subtraction is any technique which allows an image's foreground to be extracted for further processing (object recognition etc.). Many applications do not need to know everything about ...
