2. Hidden-line removal - Wikipedia

   en.wikipedia.org/wiki/Hidden-line_removal

   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 ...

3. Hidden-surface determination - Wikipedia

   en.wikipedia.org/wiki/Hidden-surface_determination

   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.

4. Painter's algorithm - Wikipedia

   en.wikipedia.org/wiki/Painter's_algorithm

   A fractal landscape being rendered using the painter's algorithm on an Amiga. The painter's algorithm (also depth-sort algorithm and priority fill) is an algorithm for visible surface determination in 3D computer graphics that works on a polygon-by-polygon basis rather than a pixel-by-pixel, row by row, or area by area basis of other Hidden-Surface Removal algorithms.

5. Error diffusion - Wikipedia

   en.wikipedia.org/wiki/Error_diffusion

   Most printers overlap the black dots slightly, so there is not an exact one-to-one relationship to dot frequency (in dots per unit area) and lightness.Tone scale linearization may be applied to the source image to get the printed image to look correct.

6. Spatial anti-aliasing - Wikipedia

   en.wikipedia.org/wiki/Spatial_anti-aliasing

   In computer graphics, anti-aliasing improves the appearance of "jagged" polygon edges, or "jaggies", so they are smoothed out on the screen. However, it incurs a performance cost for the graphics card and uses more video memory. The level of anti-aliasing determines how smooth polygon edges are (and how much video memory it consumes).

7. Dilution of precision (computer graphics) - Wikipedia

   February 2021) (Learn how and when to remove this message) ( Learn how and when to remove this message ) Dilution of precision is an algorithmic trick used to handle difficult problems in hidden-line removal , caused when horizontal and vertical edges lie on top of each other due to numerical instability .
