Difference between simple and symmetrical dda line drawing algorithm?
"Simple DDA" does not require special skills for implementation.
What is are advatages and disadvatages of bresenham's line algorithm?
1. High accuracy. Comparing to Basic Incremental algorithm (especially if the slope were > 1.) 2. High speed. Comparing to Digital Differenmtial algorithm. 3. Draws the line between any two points. Comparing to Basic Incremental algorithm which can't draw if x0 > x1 ( the format is: (x0, y0), (x1, y1). )

What are the advantages of bresenhams's line drawing algorithm over the cartesian slope ana ddadigitial defrantial analyser?
DDA uses float numbers and uses operators such as division and multiplication in its calculation. Bresgenham's algorithm uses ints and only uses addition and subtraction. Due to the use of only addition subtraction and bit shifting (multiplication and division use more resources and processor power) bresenhams algorithm is faster than DDA in producing the line. Im not sure, though if i remember right, they still produce the same line in the end. One note concerning efficiency: Fixed point DDA algorithms are generally superior to Bresenhams algorithm on modern computers. The reason is that Bresenhams algorithm uses a conditional branch in the loop, and this results in frequent branch mispredictions in the CPU. Fixed point DDA also has fewer instructions in the loop body (one bit shift, one increment and one addition to be exact. In addition to the loop instructions and the actual plotting). As CPU pipelines become deeper, mispredictions penalties will become more severe. Since DDA uses rounding off of the pixel position obtained by multiplication or division, causes an accumulation of error in the proceeding pixels whereas in Bresenhams line algorithm the new pixel is calculated with a small unit change in one direction and checking of nearest pixel with the decision variable satisfying the line equation.
What are the Disadvantages of Cohen Sutherland Line clipping algorithm?
It can only be used on a rectangular clip window.
