As you can see in the previous pages of the site, the marching cubes algorithm is a 3D iso-surface representation technique. In order to explain this technique, we are going to indroduce the marching squares algorithm which uses the same approach in 2D. read more
It's an algorithm for generating 2-dimensional contours: Marching squares. Here's a sample application: SPH Viscoelastic Fluid Simulation - Marching Squares - with mouse interaction - source at: alexnasser.co.uk. read more
Marching squares is a computer graphics algorithm that generates contours for a two-dimensional scalar field (rectangular array of individual numerical values). A similar method can be used to contour 2D triangle meshes. read more
Following the marching squares algorithm we can adapt our approach to the 3D case : this is the marching cubes algorithm. In a 3D space we enumerate 256 different situations for the marching cubes representation. read more
