The native floating-point implementation requires one addition and one rounding operation per interpolated value e. Retrieved from ” https: This page was last edited on 17 Julyat Please alggoritma to improve this article by introducing more precise citations. They can be extended to non linear functions, such as perspective correct 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. For lines with slope greater than 1, we reverse the role of x and y i.

Similar calculations are carried out to determine pixel positions along a line with negative slope.

DDAs are used for rasterization of lines, triangles and polygons. Aogoritma line is then sampled at unit intervals in one coordinate and corresponding integer values nearest the line path are determined for the other coordinate. In fact any two consecutive point x,y lying on this line segment should satisfy the equation.
