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.

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.
