DDA and Bresenham’s Line Drawing Algorithm

DDA and Bresenham’s Line Drawing Algorithm

DDA and Bresenham’s Line Drawing Algorithm     DDA (Digital Differential Analyzer) Line Drawing Algorithm: It is a mechanical device for integrating differential equations by simultaneously incrementing x and y in small steps proportional to DX and DY. The line end points are (xa,ya) and (xb,yb).   Step 1:    Compute DX and DY DX=xb-xa DY=yb-ya   Step 2:   Calculate Steps ... Read More »

MidPoint Circle Algorithm

MidPoint Circle Algorithm

MidPoint Circle Algorithm   MidPoint Circle Algorithm: A circle is defined as the set of points that are all at a given distance r from a center position (Xc,Yc). Along the circle section from x=0 to x=y in the first quadrant, the slope of the curve varies from 0 to –1. therefore , we can take unit steps in the ... Read More »
