Wrangle Node Example - Fractals

In 2015 I had created a C++/OpenGL version of Mandelbrot and Julia Sets as seen on
MathForVFX/Fractals.html

If you would like to experiment with this the executable is available here (requires unzipping)

I have also implemented these in a python node in Houdini. If you are learning vex and come from a python background the comparison might be helpful.

Below is a quick version in point wrangle. It is not as fast as the compiled code above, however it is still quite fast.

Loving point wrangle nodes.

The essential elements of code appear below. These were generated with radius 4, 1000 iterations, xmin -1.5, ymin -1.0 and width, height 2.0.

One wrangle node for calculation (pointwrangleCalculate code pictured below) and one wrangle node for color (pointwrangleColor - uses a ramp)

And for fun, manipulating the equations slightly:
