Detailed Description

calculate an image of a section of the mandelbrot set

to demonstrate that vspline's transform routines don't have to use b-splines at all, here's a simple example creating a functor to perform the iteration leading to the mandelbrot set, together with a vspline::domain adapting the coordinates and another functor to do the 'colorization'. The three functors are chained and fed to vspline::transform() to yield the image.

compile with:

./examples.sh mandelbrot.cc

./hwy_mandelbrot_clang++ -2 -1 1 1

( -2 , -1 ) being lower left and ( 1 , 1 ) upper right

the result will be written to 'mandelbrot.tif'
