Program Aplikasi Algoritma DDA, Bresenham dan Lingkaran Menggunakan Borland Delphi 7

For the digital implementation of a differential analyzer, see Digital differential analyzer. DDAs are used for rasterization of lines, triangles and polygons. From Wikipedia, the free encyclopedia.

alhoritma In computer graphicsa digital differential analyzer DDA is hardware or software used for interpolation of variables over an interval between start and end point. A line is then sampled at unit intervals in one coordinate and corresponding integer values nearest the line path are determined for the other coordinate.

This article is about a graphics algorithm.

This process is only efficient when an FPU with fast add dda rounding operation will be available. By using this site, you agree to the Terms of Use and Privacy Policy. Subscript k takes integer values starting from 0, for the 1st point and increases by 1 until endpoint is reached. They can be extended to non linear functions, such as perspective correct texture mappingquadratic curvesand traversing algorittma.
