In computer graphicsa digital differential analyzer DDA is hardware or software used for interpolation of variables over an interval between start and end point.

DDAs are used for rasterization of lines, triangles and polygons. They can be extended to non linear functions, such as perspective correct texture mappingquadratic curvesand traversing voxels.

The DDA method can be implemented using floating-point or integer arithmetic. The native floating-point implementation requires one addition and one rounding operation per interpolated value e.

This process is only efficient when an FPU with fast add and rounding operation will be available. The fixed-point integer operation requires two additions algorltma 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. A linear DDA starts by calculating the smaller of dy or dx for a unit increment of the other. 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.

Subscript k takes integer values starting from 0, for the 1st point and increases by 1 until endpoint is reached. For lines with slope greater than 1, we reverse the role of x and y i.
