[comp.graphics] Mandelbrot bug squashed

numccann@ndsuvax.UUCP (Lester I. McCann) (08/12/89)

Thanks to pell@isy.liu.se, I discovered why I was having so much trouble
with the Mandelbrot algorithm from Appendix D of The Science of Fractal
Images.  In the routine MDisk, the line listed as

	irad := INT(dist*side)

ought to be

	irad := INT(dist / side * (n-1))

A rather significant change, I'd say.
