# Mandelbrot
|
|
|
|
An implementation of the the Mandelbrot set exercise from the end of
|
|
chapter two of O'Reilly's
|
|
[*Programming Rust*](http://shop.oreilly.com/product/0636920040385.do).

I have deviated from the original in two ways, one major, one minor.
|
|
|
|
First, I've made the rendering plane, which maps from the cartesian
|
|
(pixel) plane to the complex plane, into a struct, and put all the major
|
|
rendering features into an implementation on that struct. By adding a
|
|
simple method, `subplane()`, I was able to make crossbeam rendering much
|
|
simpler and easier to read by providing horizontal slices of the pixel
|
|
plane, and I was also able to avoid recalculating the relationship
|
|
between the two planes for every pixel. A small performance boost, but
|
|
worthwhile.
|
|
|
|
Second, the output is PNM rather than PNG. I'm a huge PNM partisan, and
|
|
you kids better get off my lawn.
