What is Antialiased line?

In computer graphics, antialiasing is a software technique for diminishing jaggies – stairstep-like lines that should be smooth. Jaggies occur because the output device, the monitor or printer, doesn’t have a high enough resolution to represent a smooth line. Antialiasing is sometimes called oversampling.

### What is mid point line algorithm?

INTRODUCTION The Midpoint line algorithm is an incremental line plotting algorithm i.e. at each step we make incremental calculations based on preceding step to find next y value, in order to form a close approximation to a straight line between two points.

How do you solve Bresenham algorithm?

Calculate ΔX and ΔY from the given input.

1. ΔX = Xn – X0 = 30 – 20 = 10.
2. ΔY =Yn – Y0 = 18 – 10 = 8.

#### Which is the best algorithm for anti aliasing?

Line needs to go through a process called Rasterization which would determine color of individual pixels . Several algorithms can be used like Bresenham’s Line Algorithm , Digital Differential Analyzer , Xiaolin Wu’s line algorithm , Gupta-Sproull algorithm . Later two perform anti-aliasing or line smoothing.

How is the Bresenham algorithm used in line drawing?

Bresenham Line Drawing Algorithm attempts to generate the points between the starting and ending coordinates. The points generation using Bresenham Line Drawing Algorithm involves the following steps- Calculate ΔX and ΔY from the given input. Calculate the decision parameter P k.

## Which is faster Xiaolin Wu’s algorithm or Bresenham’s?

A naive approach to anti-aliasing the line would take an extremely long time. Wu’s algorithm is comparatively fast, but is still slower than Bresenham’s algorithm. The algorithm consists of drawing pairs of pixels straddling the line, each coloured according to its distance from the line. Pixels at the line ends are handled separately.

Which is more accurate Dda or Bresenham algorithm?

It executes fast but less faster than DDA Algorithm. The points generated by this algorithm are more accurate than DDA Algorithm. It uses fixed points only. Though it improves the accuracy of generated points but still the resulted line is not smooth. This algorithm is for the basic line drawing. It can not handle diminishing jaggies.
