Let (xc,yc) be the centre of the circle

Let r be the radius of the circle

Let d be 3-2*r (d for decision)

Let x be 0

Let y be r

Repeat while x is less than y:

Increment x

If d is less than zero

Let d be d + ( 4 * x ) + 6

Else

Decrement y

Let d be d + (( x - y ) * 4 ) + 10

End if

Plot 8 points:

( xc+x, yc+y )

( xc-x, yc+y )

( xc+x, yc-y )

( xc-x, yc-y )

( xc+y, yc+x )

( xc-y, yc+x )

( xc+y, yc-x )

( xc-y, yc-x )

End repeat

what is difference between mid-point and bresenhams circle algorithm what is difference between mid-point and bresenhams circle algorithm bresenhams circle algorithm results in a much more smoother circle,comparred to midpoint circle algorithm..In mid point,decision parameter depends on previous decision parameter and corresponding pixels whereas in bresenham decision parameter only depends on previous decision parameter...

These two algorithms are almost completely different. The only real similarity is that they are each designed to use only integer addition/subtraction and multiplication, avoiding expensive division and floating point operations.

couple of reasons.... if you are drawing and dimensioning with a Why_would_it_be_innapropriate_to_dimension_to_a_feature_on_a_surface_that_is_not_perpendicular_to_the_line_of_sightprogram the dimension will be inaccurate... If it is mechanical drawing then the fabricator would not have enough information to accurately measure the component. ie a circle turned a few degrees away from perp. would appear to be an ellipse. and may actually dimension that way
