Editing Discrete geometry (section)

===Digital geometry===
{{main|Digital geometry}}
'''Digital geometry''' deals with [[discrete space|discrete]] sets (usually discrete [[Point (geometry)|point]] sets) considered to be [[digitizing|digitized]] [[scale model|models]] or [[image]]s of objects of the 2D or 3D [[Euclidean space]].

Simply put, '''digitizing''' is replacing an object by a discrete set of its points. The images we see on the TV screen, the [[raster graphics|raster]] display of a computer, or in newspapers are in fact [[Digital data|digital]] images.

Its main application areas are [[computer graphics]] and [[image analysis]].<ref>See [https://www.springer.com/us/book/9783319120980 Li Chen, Digital and discrete geometry: Theory and Algorithms, Springer, 2014. ]</ref>
