Ppt computer graphics 5. It is defined by its two end points the slope intercept equation for a line. In the following three alg.

Line drawing on the computer means the computer screen is dividing into two parts rows and columns. But in the case of computer graphics we can not directly join any two coordinate points for that we should calculate intermediate points coordinate and put a pixel for each intermediate point of the desired color with help of functions like putpixelx y k in c where xy is our co. In case we have to draw a line on the computer first of all we need to know which pixels should be on.

How many points will needed to generate such line. View by category toggle navigation. Line generation algorithm a line connects two points.

Dda line drawing algorithm in computer graphics with solved examples. In any 2 dimensional plane if we connect two points x0 y0 and x1 y1 we get a line segment.
