Marching Cubes
An application of the marching cubes algorithm, a method used in creating 3D shapes, in the Unity Game Engine (https://unity.com/). Here are some examples of what it can produce:
The algorithm works by creating a 3D array of densities (a float within the range [0-1]) and then sampling each density. Depending on whether the density is above or below a surface threshold. Then, a mesh (that can be split up into discrete chunks) is drawn around the surface.
Attached is a more detailed explanation of the implementation: http://paulbourke.net/geometry/polygonise/
