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

This page was last edited on 17 Julyat This process is only efficient when an FPU with fast add and rounding operation will be available. For the digital implementation of a differential analyzer, see Digital differential analyzer. In computer graphicsa digital differential analyzer DDA is hardware or software used for interpolation of variables over an interval between start and end point.

Views Read Edit View history. DDAs are used for rasterization of lines, triangles and polygons. For lines with slope greater than 1, we reverse the role of x and y i.

They can be extended to non linear functions, such as perspective correct texture mappingquadratic curvesand traversing voxels. The native floating-point implementation requires one addition and one rounding operation per interpolated value e. A linear DDA dra by calculating the smaller of dy or dx for a unit increment of the other.

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

Computer graphics algorithms Digital geometry. The fixed-point integer operation requires two additions per output cycle, and in case of fractional part overflow, one additional increment and subtraction. Similar calculations are carried out to determine pixel positions along a line with negative slope.

A algoditma is then sampled at unit intervals in one coordinate and corresponding integer values nearest the line path are determined for the other coordinate.
