Custom Shortest Path

This is not a tutorial. It's a hiplc file.

The image that is used to create the effect is NOT included in the package but it works with any image that you want to use. it works best with high contrast portraits with flat white or black background.

You need intermediate knowledge of Houdini and VEX to understand the setup. I'm creating a KD tree from the image first and then using a relatively simple sop solver I'm finding the nearest points that are not connected and grow from there.
