Subscript k takes integer values starting from 0, for the 1st point and increases algorktma 1 until endpoint is reached. This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations.

Digital differential analyzer (graphics algorithm)

The native floating-point implementation requires one addition and one rounding operation per interpolated value e. Views Read Edit View history.

Computer graphics algorithms Digital geometry. DDAs are used for rasterization of lines, triangles and polygons.


In computer graphicsa digital differential analyzer DDA is hardware or software used for interpolation of variables over an interval between start and end point. The DDA method can be implemented using floating-point or integer arithmetic.

Articles lacking in-text citations from June All articles lacking in-text citations Articles with example C code. For the digital implementation of a differential analyzer, see Digital differential analyzer.

They can be extended to non linear functions, such as perspective qlgoritma texture mappingquadratic curvesand traversing voxels.

The fixed-point integer operation requires two additions per output cycle, and in case of fractional part overflow, one additional increment and subtraction. In fact any two consecutive point x,y lying on this line segment should satisfy the equation.

Similar calculations are carried out to determine pixel positions along a line with negative slope. For lines with slope greater than 1, we reverse the role of x and y i.


Retrieved from ” https: A line is then sampled at unit intervals algotitma one coordinate and corresponding integer values nearest the line path are determined for the other algorirma. This page was last edited on 17 Julyat Please help to improve this article by introducing more precise citations. A linear DDA starts by calculating the smaller of dy or dx for a unit increment of the other. By using this site, you agree to the Terms of Use and Privacy Policy.
