Line Drawing
Algorithm
Y
= mx+b (1)
is represent as a line equation where m is the slow and b the y intersects at the line.
tan θ = y/x
m = 〖y_2-y〗_1/(x_2-x_1 ) (2)
so,
m = 〖y_2-y〗_1/(x_2-x_1 )
from the equation 1 and 2
b = y1-x1m (3)
if the interval correspondent to y axis is called
del y and del x then
del y = m del x (4)
m = (del y)/(del x) (5)
There are two type of the line algorithm: -
