In 1966 Ivan E. Sutherland listed 10 unsolved problems in computer graphics. [3] Problem number seven was "hidden-line removal". In terms of computational complexity, this problem was solved by Frank Devai in 1986. [4] Models, e.g. in computer-aided design, can have thousands or millions of edges. Therefore, a computational-complexity approach ...
This is a list of models and meshes commonly used in 3D computer graphics for testing and demonstrating rendering algorithms and visual effects. Their use is important for comparing results, similar to the way standard test images are used in image processing.
Example of line clipping for a two-dimensional region. In computer graphics, line clipping is the process of removing lines or portions of lines outside an area of interest (a viewport or view volume). Typically, any part of a line which is outside of the viewing area is removed.
In computer graphics, a line drawing algorithm is an algorithm for approximating a line segment on discrete graphical media, such as pixel-based displays and printers. On such media, line drawing requires an approximation (in nontrivial cases). Basic algorithms rasterize lines in one color.
The Warnock algorithm is a hidden surface algorithm invented by John Warnock that is typically used in the field of computer graphics. [1] It solves the problem of rendering a complicated image by recursive subdivision of a scene until areas are obtained that are trivial to compute.
While algorithms such as Wu's algorithm are also frequently used in modern computer graphics because they can support antialiasing, Bresenham's line algorithm is still important because of its speed and simplicity. The algorithm is used in hardware such as plotters and in the graphics chips of modern graphics cards.
The computer graphics pipeline, also known as the rendering pipeline, or graphics pipeline, is a framework within computer graphics that outlines the necessary procedures for transforming a three-dimensional (3D) scene into a two-dimensional (2D) representation on a screen. [1]
Adobe Streamline is a discontinued line tracing program developed and published by Adobe Systems.Its primary purpose is to convert scanned bitmaps into vector artwork. Streamline is similar in function to competitors, such as Corel Trace, but was advertised as a standalone rather than an additional utility within a full drawing suit
