Question

Write this using java 

Write a complete version of the Bresenham Midpoint algorithm to handle ALL slope values.

m = 0

m > 0 

m < 0

m = 1

m  > 1 swap the rolls of x and y

m < 1

m = infinity ( needs special test case)


Include appropriate tests for ‘special case’ conditions. Instead
of “WritePixel” write to the screen the coordinates of the pixel that would be drawn. 

 

Please provide photos that it works and so I can understand the code better

Bresenham's Midpoint All Integer Line Scan Algorithm
WritePixel(x0,y0)
x=x0; y=y0
dx=x1-x0; dy=y1-y0
d=2dy - dx
no
incrE=2dy
incNE=2(dy-dx)
-d<=0
no
yes
d=d+incrNE d-d+incrE
y=y+1
X=X+1
WritePixel(x,y)
-X=X1
