100% pen. This project uses a modified version of an algorithm called "Marching Cubes". The algorithm allows you to render the surfaces of 3d objects using triangles. It's often used in games, and allows smooth editable terrain to be made with relatively little processing power. However, this version that I made is 2D, not 3D, and since it contains no cubes, it is marching squares. If you want more information on the algorithm, Sebastian Lague has a great youtube video on the subject, I'd highly suggest looking it up.
