## What is line algorithm in computer graphics?

In computer graphics, a line drawing algorithm is an algorithm for approximating a line segment on discrete graphical media, such as pixel-based displays and printers. On such media, line drawing requires an approximation (in nontrivial cases). Basic algorithms rasterize lines in one color.

### What are the various line drawing algorithms?

Types of Line Drawing Algorithm

• Digital Differential Algorithm ( DDA) An incremental conversion method is a DDA Algorithm and also we called Digital Differential Algorithm (DDA).
• The Bresenham Line Algorithm. The Scan conversion algorithm is Bresenham-algorithm.

#### What is 2d explain DDA line generation algorithm?

DDA Algorithm is the simplest line drawing algorithm. Given the starting and ending coordinates of a line, DDA Algorithm attempts to generate the points between the starting and ending coordinates.

Which one is a line generating algorithm?

Bresenham’s Line Generation The Bresenham algorithm is another incremental scan conversion algorithm. The big advantage of this algorithm is that, it uses only integer calculations. Moving across the x axis in unit intervals and at each step choose between two different y coordinates.

How a line is represented in computer graphics?

A line connects two points. It is a basic element in graphics. To draw a line, you need two points between which you can draw a line. In the following three algorithms, we refer the one point of line as X0,Y0 and the second point of line as X1,Y1.

## How do you draw a line in computer graphics?

Draw a line from current point to point(x,y) using lineto() function. lineto() is a library function of graphics. h and it can be used to draw a line from current point to specified point.

### Why we use DDA line algorithm?

In computer graphics, a 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.

#### Which is the accurate and efficient line generating algorithm?

Explanation: Bresenham’s line algorithm is a very efficient and accurate algorithm. Explanation: If there are ‘n’ processes then this algorithm divides it into number of partitions and generates line segments.

Which algorithm is efficient for line drawing?

4. Bresenham’s Line Algorithm is more accurate and efficient at DDA Algorithm. 5. Bresenham’s Line Algorithm can draw circle and curves with more accurate than DDA Algorithm.

How is line used in graphic design?

Line is used to add style, enhance comprehension, create forms, and divide space by being a border around other design elements or divider between them. Lines can also be used alone or in combination with other graphic design elements to set moods, create textures, define shapes, and build patterns.

## What are the basic line functions in computer graphics?

line function is used to draw a line from a point(x1,y1) to point(x2,y2) i.e. (x1,y1) and (x2,y2) are end points of the line. The code given below draws a line. // mode that generates image using pixels.

### Which is the correct algorithm for line generation?

In the following three algorithms, we refer the one point of line as X 0, Y 0 and the second point of line as X 1, Y 1. Digital Differential Analyzer D D A algorithm is the simple line generation algorithm which is explained step by step here. Step 1 − Get the input of two end points ( X 0, Y 0) and ( X 1, Y 1).

#### Which is the algorithm for drawing a line?

Line Generation Algorithm. A line connects two points. It is a basic element in graphics. To draw a line, you need two points between which you can draw a line. In the following three algorithms, we refer the one point of line as \$X_{0}, Y_{0}\$ and the second point of line as \$X_{1}, Y_{1}\$.

Which is the DDA algorithm for line generation?

DDA Algorithm Digital Differential Analyzer DDA algorithm is the simple line generation algorithm which is explained step by step here. Step 1 − Get the input of two end points (X0, Y0) and (X1, Y1). Step 2 − Calculate the difference between two end points.

What is the idea of Bresenham’s line generation algorithm?

The idea of Bresenham’s algorithm is to avoid floating point multiplication and addition to compute mx + c, and then computing round value of (mx + c) in every step. In Bresenham’s algorithm, we move across the x-axis in unit intervals.
